With advanced technology and strict quality control, Hengde chillers have a good reputation in the market and are widely used in many scenarios such as industrial production and scientific research experiments, providing reliable refrigeration support for customers' production and operation. However, to ensure the safe and efficient operation of the industrial chiller, correct operation and maintenance are of utmost importance. The following are the precautions and warnings for Hengde chillers.   I. Operating Precautions for Chillers 1. The chilled water pump of the chiller must not operate when there is no water in the water tank. 2. Try to avoid continuous switching of the operation switch. 3. When the chilled water temperature of the chiller reaches the set temperature, the compressor will automatically stop running. This is a normal phenomenon. 4. The temperature switch should be set above 5°C to prevent the evaporator from freezing (except for low - temperature units). 5.To ensure the best cooling effect and keep the chiller in optimal condition, regularly clean the condenser, evaporator, and water filter of the industrial chiller.   II. Electrical Precautions 1. Only after the unit is shut down and the power is turned off can the industrial chiller be cleaned. Otherwise, there may be a risk of electric shock or injury. 2. Do not directly rinse the chiller with water, and do not perform maintenance when the chiller is in operation. 3. Do not use steel wire or copper wire to replace the circuit breaker. Use the correct - specification fuse to avoid damaging the industrial chiller. 4. If a fault alarm occurs, immediately shut down the unit. Restart it only after the fault is eliminated, or promptly notify the maintenance personnel for handling. Continuing to use the chiller in this situation may cause electric shock or fire accidents. 5. Warranty work can only be carried out by professionals. Before removing the electrical wiring device, all power sources must be cut off.   III. Warnings 1. Never twist or pull the wires of the controller to avoid damaging the controller and causing malfunctions. 2. Never wipe the controller with benzene, thinners, or chemicals. Otherwise, it may cause discoloration or component malfunctions. To clean it, first soak a cloth in water containing a neutral detergent, wring out the water, wipe the controller, and then dry it with a dry cloth. 3. Never apply excessive force to the operation screen or connection parts to avoid color changes.   Hengde Company always pays attention to the customer - use experience.

For many manufacturers around the world, China has become one of the leading sources of industrial cooling equipment. Competitive pricing, strong manufacturing capabilities, and flexible customization make Chinese suppliers an attractive option.   However, importing an industrial chiller is very different from buying a standard product online. Cooling capacity, electrical specifications, shipping methods, customs documentation, and after-sales support all influence whether the project runs smoothly.   If you're planning to purchase an industrial chiller from China for the first time, this guide covers the most important things to consider before placing an order.   Start by Choosing the Right Industrial Chiller Before comparing suppliers, make sure you've selected the right type of equipment. Many buyers begin by asking for a quotation based only on cooling capacity. In reality, cooling capacity alone is not enough to determine the correct model.   A professional supplier will usually ask questions such as: 1）How many cooling capacity do you need?  Such as 15kw, 20kw... Or how many m³ of water/solution need to be cooled? 2）What's the orginal temperature ?  3）What's the chilled temperature required ? 4）How long you want to cool down ? Like one houre less or more 5）What's your power supply ?   6）Where is the chiller applied ? 7)  Air Cooled Chiller or Water Cooled Chiller? If you don't know, that's okay; the manufacturer will give you professional advice. 8）How many sets ? The more complete the information you provide, the more accurate the equipment selection will be.   Hengde Insight：The fastest quotation is not always the best quotation. If a supplier recommends a model without asking technical questions, there's a higher chance the equipment won't match your actual application.   Choose Between Air-Cooled Chillers and Water-Cooled Chillers One of the first technical decisions is the cooling method. Air-cooled industrial chillers are easier to install because they do not require cooling towers. They are suitable for factories with limited installation space or locations where water resources are limited.   Water-cooled industrial chillers usually provide higher efficiency for medium and large cooling loads. However, they must operate together with a cooling tower.   The choice should depend on your production conditions rather than equipment price alone. For more：Choosing Between Air Cooled And Water Cooled Chillers: Which One Is Right For You?   Don't Focus Only on the Price Price is naturally important, but it shouldn't be the only factor. Industrial chillers are long-term production equipment. Compressor brands, pump quality, electrical components, control systems, and heat exchangers all influence reliability and maintenance costs.   A lower purchase price may result in higher operating costs over the equipment's lifetime.   Hengde Insight：Many experienced buyers evaluate the total cost of ownership instead of the purchase price alone. Downtime is often far more expensive than the difference between two quotations.   Confirm Technical Specifications Before Production Once you've selected a supplier, carefully confirm all technical details before manufacturing begins.  Items worth checking include: Cooling capacity Refrigerant type, especially EU countries. Electrical specifications Water connections Pump pressure Controller language Communication interface (if required) Machine dimensions Nameplate information   Making changes after production starts is usually much more expensive than confirming everything in advance.   Ask for Factory Testing Before shipment, most professional manufacturers perform a complete factory test.   Requesting photos or videos of the testing process can help confirm that the industrial chiller operates correctly before it leaves the factory. Some buyers also request: Temperature test reports Electrical test reports Nameplate photos Packing photos These documents can reduce misunderstandings after delivery.   Understand Shipping Options Industrial chillers are usually transported by sea because of their size and weight.   Depending on the equipment dimensions, shipments may be arranged as: LCL (Less than Container Load) FCL (Full Container Load) Open Top Container (for oversized equipment) Flat Rack Container (for special projects) Proper export packing is equally important.   Most manufacturers use wooden crates or steel-frame packaging to protect the equipment during international transportation.   Prepare the Necessary Import Documents Before customs clearance, buyers should confirm which documents are required in their country. Common export documents include: Commercial Invoice Packing List Bill of Lading Certificate of Origin (if required) User Manual Electrical Drawings Test Report (if requested)   Different countries may have additional certification requirements, so it's always worth checking local import regulations before placing an order.   Think Beyond Delivery Receiving the equipment is only the beginning. Before purchasing, ask your supplier about: Installation guidance Wiring diagrams Spare parts availability Online technical support Warranty policy   A supplier that continues to provide technical assistance after delivery is often more valuable than one offering the lowest quotation.   Hengde Insight：The quality of after-sales support is difficult to evaluate before purchase—but it becomes one of the most important factors after the equipment arrives.   Build a Long-Term Partnership Many factories import industrial chillers more than once. As production expands, customers often require additional chillers, spare parts, or customized cooling systems.   Working with a reliable manufacturer who understands your production process can simplify future projects and reduce communication time.   Hengde Insight：The best supplier isn't necessarily the one with the lowest price. It's the one who already understands your factory before you place your second order.   How Hengde Can Help With more than 20 years of manufacturing experience, Hengde supplies industrial chillers to customers in plastics processing, chemical manufacturing, electroplating, food processing, marine engineering, and lithium battery production worldwide.   We offer air cooled chillers, water cooled chillers, screw chillers, scroll chillers, and customized process cooling solutions tailored to each customer's production requirements.   From equipment selection and engineering support to  factory testing, export packing, and after-sales service, Hengde works closely with customers throughout the entire importing process, making it easier to purchase reliable industrial chillers from China with confidence.

When buying an industrial chiller, choosing the right manufacturer can be just as important as choosing the right cooling capacity. For industrial applications, a industrial chiller is not simply a refrigeration machine. It becomes part of the production process and directly affects temperature stability, equipment performance, product quality, and operating costs.   For buyers looking for an OEM industrial chiller manufacturer, the key question is not only “How much does the chiller cost?” but also whether the manufacturer can understand the process, provide the correct configuration, customize the equipment when necessary, and support the project after delivery.   Table of Contents Quick Answer Key Takeaways What Should You Look for in an OEM Industrial Chiller Manufacturer? Industrial Chiller Selection: What Buyers Should Prepare OEM Manufacturer vs Trading Company When Do You Need a Customized Industrial Chiller? Real Experience: Hengde Industrial Chiller Project FAQ Why Choose Hengde?   Quick Answer An experienced OEM industrial chiller manufacturer should be able to do more than assemble standard components. A reliable supplier should help you determine the required cooling capacity, water temperature, flow rate, pump head, condenser type, compressor configuration, power supply, and control requirements.   For standard production lines, an off-the-shelf industrial chiller may be sufficient. However, applications involving high ambient temperatures, low-temperature cooling, corrosive environments, explosion-proof requirements, unusual power supplies, or large flow rates may require a customized solution.   Hengde Insight：In our experience, the cheapest chiller is rarely the cheapest solution over its entire service life. A slightly higher initial investment in the correct configuration can often reduce temperature problems, maintenance work, and unexpected production downtime.   Key Takeaways Cooling capacity should be calculated from the actual process load rather than equipment horsepower alone. The required chilled water temperature and flow rate are critical to chiller selection. Air-cooled chillers are generally easier to install, while water-cooled chillers can be suitable for larger systems when a cooling tower and cooling-water system are available. OEM capability becomes especially important for customized voltage, low-temperature operation, corrosion resistance, explosion-proof requirements, and special control systems. Buyers should evaluate the manufacturer's engineering, testing, spare parts, warranty, and after-sales capabilities—not only the quotation.   What Should You Look for in an OEM Industrial Chiller Manufacturer? Not every company selling industrial chillers is an actual manufacturer. Some companies mainly purchase standard units from other factories and resell them. This can make communication more complicated when the project requires technical modifications.   A genuine OEM manufacturer should normally have its own production, engineering, testing, and quality-control capabilities. It should also be able to explain why a particular compressor, evaporator, condenser, pump, refrigerant, or control configuration is recommended for your application.   For industrial buyers, several areas deserve particular attention: Engineering capability: Can the supplier calculate and recommend the correct configuration? Production capability: Does the company have its own manufacturing facility? Customization: Can voltage, frequency, control systems, water connections, materials, and other requirements be modified? Testing: Is every unit tested before shipment? After-sales support: Can the manufacturer provide troubleshooting assistance, spare parts, and technical support?   Industrial Chiller Selection: What Buyers Should Prepare Before contacting an OEM industrial chiller manufacturer, it is useful to prepare several basic parameters. This makes the quotation more accurate and avoids repeated technical communication. Parameter Why It Matters Cooling capacity Determines the required refrigeration output of the chiller. Water outlet temperature Affects compressor selection and refrigeration system design. Water flow rate Ensures sufficient heat transfer between the chiller and production equipment. Pump head Must match the resistance and distance of the production-line piping. Ambient temperature Important for air-cooled chiller performance and condenser selection. Power supply Voltage, phase, and frequency must match the installation site. Installation environment Special environments may require corrosion-resistant or explosion-proof designs.   Hengde Insight： One common purchasing mistake is to send only the machine model or horsepower to the chiller supplier. For industrial cooling, “20 HP” does not tell the manufacturer enough about the actual process. A good supplier should ask about the process before recommending the model.   OEM Manufacturer vs Trading Company Item OEM Manufacturer Trading Company Technical design Usually handled by an in-house engineering team May depend on an external factory Customization More flexible Depends on the actual manufacturer Production control Direct control of manufacturing Usually indirect Technical communication Direct communication with engineers is possible Information may pass through several parties After-sales support Manufacturer-level technical support Depends on supplier relationship   This does not mean every trading company is unsuitable. A professional trading company can still provide good service. However, for technically demanding industrial chiller projects, direct communication with the manufacturer can reduce misunderstandings and make customization easier.   When Do You Need a Customized Industrial Chiller? Customization does not always mean designing an entirely new chiller. In many projects, relatively small modifications can make the equipment much better suited to the production environment.   Typical requirements may include customized voltage and frequency, special water connections, larger pumps, different temperature ranges, corrosion-resistant materials, special electrical components, PLC control, RS485 communication, explosion-proof electrical configurations, or integration with an existing production line.   For example, Hengde offers different industrial chiller configurations including air-cooled and water-cooled models, scroll and screw chillers, as well as low-temperature units. Its product range covers applications from plastics and rubber to chemicals, electronics, food and beverage, marine, automotive, and surface treatment.   Real Experience: Hengde Industrial Chiller Project Nanjing Hengde Electrical Equipment Co., Ltd. was founded in 2010 and currently operates a 15,000-square-meter manufacturing facility with more than 150 experienced employees. The company provides industrial refrigeration and temperature-control equipment for customers in multiple industries and markets.   Every industrial chiller project has its own challenges. In one of our recent projects, the customer needed a reliable cooling solution for continuous industrial production, but the working conditions were more demanding than a standard chiller application.   The main challenge was to ensure stable cooling performance under long hours of continuous operation while meeting the customer's specific requirements for cooling capacity, water temperature, installation space, and site conditions. A standard off-the-shelf configuration could not fully match the application. Instead of simply recommending a larger chiller, our engineering team reviewed the customer's actual working conditions, including the required cooling temperature, water flow, operating hours, ambient conditions, and available installation space. Based on these details, we adjusted the chiller configuration and selected suitable core components to balance cooling performance, reliability, and operating cost.   Another challenge came during production. The customer's requirements required several details to be checked and confirmed before shipment. Our sales and engineering teams worked closely throughout the manufacturing process, checking the key parameters step by step and communicating with the customer whenever adjustments were needed.   The final industrial chiller was completed, tested, and prepared for shipment after passing the required performance checks. More importantly, the project showed that successful industrial cooling is not simply about choosing a chiller by horsepower. Understanding the customer's actual working conditions and solving problems during the design and production stages are what make a cooling solution reliable in real-world applications.   This is the kind of experience Hengde has built through years of manufacturing industrial chillers. When standard solutions are not enough, we focus on the application, identify the real problem, and work with the customer to develop a practical solution.   FAQ 1. What is an OEM industrial chiller manufacturer? An OEM industrial chiller manufacturer designs and produces industrial cooling equipment and can normally customize equipment according to a customer's technical requirements. 2. Should I choose an air-cooled or water-cooled industrial chiller? Air-cooled chillers are generally easier to install because they do not require a cooling tower. Water-cooled chillers use cooling water to remove heat from the refrigeration system and normally require a cooling tower, cooling-water pump, and related piping. The better choice depends on the plant environment, cooling load, water availability, and operating conditions. 3. Can an industrial chiller be customized? Yes. Depending on the manufacturer, options can include power supply, temperature range, pump capacity, materials, control system, communication functions, and special environmental requirements. 4. How do I choose the correct industrial chiller size? Start with the actual heat load, required water temperature, water flow rate, process operating schedule, and ambient conditions. Chiller horsepower alone is not a reliable sizing method. 5. What should I ask an industrial chiller manufacturer before ordering? Ask about cooling capacity, operating temperature, water flow, pump head, power supply, compressor brand, heat exchangers, refrigerant, testing procedures, warranty, spare parts, and technical support.   Why Choose Hengde as Your OEM Industrial Chiller Manufacturer?

An industrial chiller that keeps shutting down is more than a maintenance inconvenience. For a production line, repeated shutdowns can interrupt production, affect process temperature stability, and increase the risk of equipment damage.   When a customer tells an after-sales engineer, “The chiller runs for a while and then shuts down,” the first reaction should not be to replace the compressor or add refrigerant. The shutdown is usually a protection response. The more important question is: what condition caused the protection to activate?   This article explains the most common reasons why an industrial chiller keeps shutting down and provides a practical troubleshooting approach for technicians and after-sales teams. Quick Answer An industrial chiller may keep shutting down because of: High refrigerant pressure Low refrigerant pressure Insufficient chilled-water flow High ambient temperature or poor ventilation Condenser fouling or cooling-tower problems Compressor overload Three-phase voltage or phase-sequence problems Water temperature or antifreeze protection Temperature sensor or flow-switch faults Incorrect operating conditions or excessive process load The most efficient way to troubleshoot the problem is to identify the actual alarm first, then check the water circuit, electrical supply, condenser conditions and refrigeration system in a logical order.   Key Takeaways A shutdown alarm does not necessarily mean the compressor has failed. Repeatedly resetting the chiller can hide useful troubleshooting information. Water flow should be checked before making assumptions about the refrigeration circuit. Air-cooled and water-cooled chillers require different troubleshooting methods. Voltage, current, water temperature and flow should be checked while the chiller is actually running. The conditions immediately before shutdown are often more useful than the alarm itself.   Hengde Insight：A industrial chiller alarm tells you what protection was triggered, but not necessarily where the original problem started. This distinction is important. For example, a compressor overload may be the final protection action, while the real cause could be abnormal voltage, high condensing pressure or insufficient cooling-water flow.   Table of Contents Quick Answer Key Takeaways Common Reasons Why a Chiller Keeps Shutting Down High-Pressure Protection Low-Pressure Protection Insufficient Water Flow Electrical and Compressor Protection Ambient Temperature and Installation Conditions A Practical Troubleshooting Method Hengde Industrial Chiller Experience About Hengde FAQ Common Reasons Why a Chiller Keeps Shutting Down Industrial chillers are normally equipped with several protection functions. Depending on the model, these can include high-pressure protection, low-pressure protection, overload protection, flow protection, antifreeze protection, phase-loss protection and phase-sequence protection. These protections are not unnecessary interruptions. They are designed to stop the equipment before an abnormal operating condition causes more serious damage. Therefore, when a chiller repeatedly stops, technicians should avoid treating every shutdown as the same problem. For example, a chiller that stops after 5 seconds requires a different investigation from one that operates normally for two hours and then trips during peak production.   1. High-Pressure Protection High-pressure protection is a common reason for industrial chiller shutdowns, particularly during hot weather or when heat rejection is insufficient. For an air-cooled chiller, check: Condenser fins for dust and dirt Condenser fan operation Air inlet and outlet clearance Workshop ventilation Hot air recirculation Ambient temperature For a water-cooled chiller, the investigation should focus on the condenser-water side: Cooling-tower operation Condenser-water temperature Cooling-water flow Condenser fouling Cooling-water pump operation Water valves and piping A water-cooled chiller relies on the cooling-water system to remove heat from the refrigeration cycle. If the cooling tower or condenser-water circulation is not working correctly, the chiller may eventually shut down on high pressure even though the compressor itself is functioning normally.   Hengde Insight：When a high-pressure alarm occurs, don't only ask, “Is the condenser dirty?” A better question is: “Where is the refrigerant heat supposed to go, and is that heat actually being removed?” This approach helps technicians look at the complete heat-rejection system rather than one component.   2. Low-Pressure Protection Low-pressure protection requires a different troubleshooting direction. Possible causes include insufficient refrigerant, refrigerant leakage, low water temperature, restricted refrigerant flow, expansion valve problems, a blocked filter-drier or insufficient evaporator-side flow. If a technician suspects low refrigerant, simply adding refrigerant should not be considered the final solution. If a leak exists, the chiller may operate normally for a short period after refrigerant is added and then develop the same problem again. The better approach is to confirm the operating pressure, inspect the refrigeration circuit and determine whether the refrigerant charge is actually insufficient.   3. Insufficient Water Flow Water circulation problems are sometimes overlooked because technicians naturally focus on the refrigeration system when a chiller stops. However, insufficient water flow can trigger flow protection or create abnormal evaporator conditions. Check the following: Is the circulation pump operating normally? Is the water tank level sufficient? Is the filter blocked? Are valves fully open? Is there air trapped inside the piping? Is the actual flow rate sufficient? Has the process piping been modified recently? It is also useful to record the chilled-water inlet and outlet temperatures. If the temperature difference suddenly becomes abnormal, the problem may be related to water circulation or process load rather than the refrigeration compressor.   4. Electrical and Compressor Protection A compressor overload alarm does not automatically mean that the compressor is damaged. Before considering compressor replacement, check the electrical conditions while the chiller is operating: Three-phase voltage Voltage imbalance Phase loss Phase sequence Running current Electrical terminals Contactor condition Overload protection setting Loose or oxidized electrical terminals can also create intermittent problems. This is especially worth checking on older equipment or machines operating under continuous vibration and high-temperature conditions. If the chiller operates normally for 30 minutes and then trips, technicians should record the current and voltage before the shutdown whenever possible. Checking only after the machine has stopped may miss the abnormal condition.   5. Ambient Temperature and Installation Conditions The installation environment can have a direct effect on chiller performance. For air-cooled industrial chillers, insufficient ventilation or hot-air recirculation can increase condensing temperature and cause high-pressure protection. For example, a chiller may operate normally during the morning but shut down repeatedly during the hottest part of the afternoon. In this situation, ambient temperature should be recorded together with the alarm time. Also check whether the chiller has enough space for air intake and hot-air discharge. Installing several air-cooled chillers in a small enclosed room can create a local high-temperature environment even when the general workshop temperature appears acceptable.   Hengde Insight：The time of the shutdown is useful diagnostic information. If a chiller consistently trips only during peak production or the hottest period of the day, the operating condition may be more important than the chiller's basic design.   A Practical Troubleshooting Method for Technicians When an after-sales engineer receives a report that an industrial chiller “keeps shutting down,” the following sequence can make troubleshooting faster. Check the alarm first Record the alarm code or protection condition before resetting the machine. If possible, take a photo of the controller display. Check the basic conditions Confirm the power supply, water level, pump operation, valves and basic controller status. Check water flow and temperatures Measure chilled-water inlet and outlet temperatures and confirm the actual circulation condition. Check the condenser side For air-cooled units, inspect the condenser and fans. For water-cooled units, check cooling-tower performance, condenser-water temperature and flow. Check electrical parameters Measure voltage and running current under operating conditions. Do not rely only on a measurement taken after the chiller has already stopped. Check the refrigeration circuit Only after the basic conditions have been confirmed should the technician move deeper into refrigerant pressure, expansion components, filter-drier condition and other refrigeration components. This order prevents a common service mistake: replacing an expensive component before confirming whether the actual problem is caused by water flow, power supply or installation conditions.   Hengde Industrial Chiller Experience Hengde manufactures air cooled chillers and water cooled chillers for applications including plastics and rubber, chemical processing, electronics, automotive, die casting, surface treatment, marine and other industrial processes. The company's product range includes scroll, screw and low-temperature chillers. One example of the importance of looking at the complete system is the Hengde HC-20W water cooled chiller. Parameter HC-20W Cooling Capacity 60 kW / 20 HP / 15 ton Compressor 7.5 kW × 2 Pump Power 2.25 kW Cooling Air Flow 20000 m³/h Frozen Water Flow 10.3 / 12.11 m³/h Pump Power 2.25 Kw Maximum Pump Head 20 m Protection High/low pressure, overload, over-temperature, phase loss, phase sequence and other protections These specifications illustrate why chiller troubleshooting should not focus only on compressor power. Pump capacity, water flow, heat exchange and protection settings are all part of reliable operation. The HC-20W is also available with customization options depending on application requirements.    For larger industrial applications, Hengde also manufactures water-cooled screw chillers. The HC-600WD, for example, has a rated cooling capacity of 600 kW / 200 HP / 160 ton and uses two 75 kW semi-hermetic screw compressors. Its published specifications include 155 m³/h cooling-water flow and 110 m³/h chilled-water flow, together with multiple protection functions.    These examples show an important engineering principle: the chiller should be evaluated as a complete cooling system, not simply by its compressor size. About Hengde: Industrial Chiller Manufacturer Nanjing Hengde Electrical Equipment Co., Ltd. was founded in 2010 and specializes in the design, manufacturing, sales and service of industrial refrigeration and temperature-control equipment. The company has a 15,000-square-meter facility and more than 150 experienced employees, with dedicated R&D, manufacturing, testing, sales and service functions.  Hengde manufactures air-cooled chillers, water-cooled chillers, screw chillers, scroll chillers, low-temperature chillers, marine chillers, mold temperature controllers and heating & cooling integrated units.   The company reports ISO9001, CE and SGS certifications and states that its products are supplied to customers in Europe, North America, the Middle East and Southeast Asia. For a new industrial chiller project, Hengde normally needs information such as the application, required cooling capacity, inlet and outlet water temperatures, ambient temperature, voltage, flow and pressure requirements. This information helps engineers select the chiller based on the actual process instead of simply matching horsepower.   FAQ: Industrial Chiller Shutdown Problems 1. Why does my industrial chiller keep shutting down? The most common causes include high or low refrigerant pressure, insufficient water flow, compressor overload, electrical problems, high ambient temperature, condenser problems and protection triggered by abnormal operating conditions.   2. Why does my chiller restart after I reset it? A reset may temporarily clear the protection condition. If the underlying problem remains, the same protection will normally activate again when the abnormal condition returns.   3. Can low water flow cause an industrial chiller to shut down? Yes. Insufficient water flow can activate flow protection and may also cause abnormal evaporator operating conditions. Check the pump, filter, valves, piping and actual flow before assuming a refrigeration fault.   4. Why does my air-cooled chiller shut down on hot days? High ambient temperature, dirty condenser fins, poor ventilation, condenser fan problems or hot-air recirculation can increase condensing temperature and cause high-pressure protection.   5. Why does a water-cooled chiller keep shutting down? Check the cooling tower, condenser-water pump, condenser-water temperature, water flow and condenser cleanliness. The problem may be in the cooling-water system rather than the chiller itself.   6. Should I replace the compressor if the chiller has an overload alarm? Not immediately. Check three-phase voltage, current, phase balance, electrical connections, condenser conditions and operating pressure first. Compressor replacement should be considered only after the cause has been properly confirmed.   Conclusion A chiller that keeps shutting down is usually responding to an abnormal condition rather than simply “breaking down.” The fastest way to solve the problem is to identify the protection, record the operating conditions and work systematically through water flow, heat rejection, electrical supply and refrigeration performance. For technical and after-sales teams, this approach reduces unnecessary component replacement and helps identify whether the problem is actually inside the chiller or somewhere in the surrounding cooling system. The goal is not simply to restart the chiller. The goal is to understand why it stopped.   If you are selecting a new industrial chiller or experiencing repeated shutdowns on an existing cooling system, Hengde can evaluate the application based on cooling capacity, water temperature, flow, pressure, ambient conditions and other project requirements.
