Hengde Chiller

Choosing a chiller that suits your needs requires considering multiple factors. Here are some suggestions for purchasing a chiller:   1. Determine the cooling capacity of the chiller Determine the cooling capacity of the required chiller based on actual needs. For example, factories, hospitals, etc. have high requirements for cooling capacity and need to choose chillers with larger cooling capacity, such as 200kw chillers, 500kw chillers, 1000kw chillers, 1500kw chillers, etc.; while some small injection molding equipment need to choose chillers with smaller cooling capacity. Such as 5ton chillers, 8ton chillers, 10ton chillers, etc. If you don’t know or are not sure how big an industrial chiller to buy, you can tell the application industry, equipment flow, inlet and outlet water temperature, ambient temperature, refrigerant type, voltage and other special requirements, such as pump flow, pressure requirements, explosion-proof requirements, etc. Hengde Company will recommend an industrial chiller that suits your company’s needs based on all your requirements.   2.Consider the brand and after-sales service of the chiller  The quality and after-sales service of well-known brands of chillers are better, which can ensure the long-term and stable operation of the equipment. At the same time, you should also understand the warranty period and maintenance policy of the chiller. Hengde Company has more than 15 years of experience in the chiller industry, passed ISO9001, CE, SGS and other certificates, and obtained 8 patent certificates. At the same time, Hengde Company has a complete pre-sales and after-sales system, providing 24-hour customer service. Free pre-sales consultation, technical and operation training, and on-site guidance on the installation and commissioning of the chiller according to the actual needs of customers, so that you have no worries.   3.Consider the installation conditions of the chiller According to the place of use and environment, choose suitable chiller installation conditions, such as power supply, water source, ventilation conditions, etc. For some places with limited space or inconvenient water source, you can choose air-cooled chillers, which are easy to install and occupy a small area. For places with sufficient water source and high cooling requirements, you can choose water-cooled chillers, which generate relatively less noise during operation.   4.Consider the price of the chiller When purchasing a chiller, price is an important consideration. You need to choose a cost-effective device based on your budget and actual needs. But price is not the only factor. The cost-effectiveness of the chiller needs to be comprehensively evaluated based on product quality, technical support and after-sales service.   5. Safety performance and maintenance convenience Check whether the chiller has complete safety protection measures, such as high and low voltage protection, overload protection, leakage protection, etc. High and low voltage protection can prevent the compressor from being damaged under abnormal pressure, overload protection can prevent the motor from burning due to long-term overload, and leakage protection ensures the safety of the operator. Choose a chiller that is easy to maintain. For example, the structural design of the equipment should be easy to disassemble and overhaul, and key components (such as compressors, water pumps, etc.) should be easily accessible. At the same time, the manufacturer should provide detailed maintenance manuals and technical support to facilitate users to perform daily maintenance and troubleshooting.   In short, when purchasing an industrial chiller, you need to consider the above factors comprehensively according to your actual needs and situation and choose the equipment that suits you. At the same time, pay attention to the maintenance and care of the equipment to ensure its long-term stable operation.   Choose Hengde, Choose Perfect Industrial Chillers!

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.

As a leading enterprise in the industry, Hengde Company relies on the Industrial chiller to play a crucial role in various industrial production processes. It can precisely control the temperature and ensure the stable operation of production equipment, which is a key link in ensuring production efficiency and product quality. However, during long - term use, the compressor of the industrial chiller may issue some fault alarms, which not only affect the normal operation of the equipment but may also lead to production stagnation. To help you solve problems quickly and effectively, the following details the common high pressure alarm and low pressure alarm faults of the Industrial chiller compressors of Hengde Company and the corresponding solutions.     High - Pressure Alarm of Industrial chiller Compressor 1. The condenser is dirty and blocked. Solution: Clean the condenser, keep the air temperature below 40°C / keep the cooling water below 35°C.   2. The high - pressure switch trips. Solution: Press the reset button of the high - pressure switch and restart the compressor.   3. Over - charging of refrigerant. Solution: Check whether the refrigerant charging amount is excessive.   4. Cooling water pump failure. Solution: Repair or replace the water pump.   Low - Pressure Alarm of Industrial chiller Compressor 1. Insufficient refrigerant or refrigerant system leakage. Solution: Check whether the system lacks refrigerant or whether there is leakage in the system pipelines.   2. Insufficient water flow or system shortage causes the evaporator to freeze. Solution: Check whether the water tank is short of water and whether the valve is fully opened. If the evaporator freezes, drain the water completely and then add warm water to melt it. Do not knock the ice with hard objects, as piercing the copper tube will damage the compressor!   3. Chilled water pump failure or pipeline blockage. Solution: Check the chilled water pump and pipeline system.   Hengde Company has always been committed to providing customers with high quality Industrial chiller equipment and complete after - sales services.

For many shipowners and offshore project contractors, the biggest concern when selecting a cooling system is not the cooling capacity itself — it is whether the equipment can survive the environment.   High salt concentration, humid air, continuous vibration, and 24-hour operation create conditions that are far more demanding than ordinary industrial factories. A standard chiller that performs well indoors may begin showing corrosion, electrical instability, or efficiency loss within a surprisingly short time after being deployed offshore. So, can marine chillers really operate reliably in these conditions?   From our experience at Hengde Chiller, the answer is yes — but only if the system is designed specifically for marine environments rather than simply adapted from a standard industrial chiller.   Salt Air Damages Equipment Faster Than Many Users Expect One thing many first-time marine project buyers underestimate is that salt corrosion does not only affect the external metal casing.   In reality, salt-laden air slowly enters almost every part of the system, including electrical terminals, condenser fins, copper joints, fan motors, and even sensor connections. Over time, this can create oxidation layers that reduce conductivity and cooling efficiency.   In many offshore projects, the earliest failures are often not compressors or refrigerant systems — they are small electrical connection points and terminals that gradually corrode because of moisture mixed with salt particles. This is why professional marine chillers usually place heavy focus on electrical protection, not just refrigeration performance.   At Hengde, marine chillers are typically equipped with: Corrosion-resistant structural materials Protective coatings for metal components Moisture-resistant electrical cabinet design Reinforced piping protection Stable control systems for continuous operation These details may seem minor during purchasing, but they become critical after several months of offshore use.   Humidity Is Sometimes More Dangerous Than Seawater Most people immediately think about seawater corrosion when discussing marine cooling systems. However, in practical operation, humidity itself can become an even bigger hidden risk.   When humid air enters electrical cabinets and meets temperature differences caused by cooling systems, condensation can form inside the equipment. Once moisture accumulates on electrical components, unstable signals and unexpected shutdowns may occur.   In coastal environments, repeated condensation inside electrical cabinets is often more harmful than occasional seawater exposure because operators may not notice the issue until electrical faults begin appearing intermittently. This is one reason marine chillers require better sealing and ventilation design compared with standard industrial chillers.   Humidity Is Sometimes More Dangerous Than Seawater Most people immediately think about seawater corrosion when discussing marine cooling systems.

This is one reason marine chillers require better sealing and ventilation design compared with standard industrial chillers.     Stable Operation Matters More Than Extreme Cooling Capacity Some buyers focus heavily on achieving the lowest possible temperature. But in marine applications, stability is usually more important than extreme cooling performance. A marine chiller running continuously at moderate, stable conditions will generally outperform a system constantly pushed near its maximum operating limit.   For offshore projects, slightly oversized chillers often achieve longer service life because the compressor operates under lower stress during continuous operation. This is especially important on vessels or offshore platforms where maintenance opportunities are limited.   At Hengde, many customers prefer customized marine chillers with operating margins built into the design, especially for tropical coastal regions where ambient temperatures and humidity remain high year-round.   Vibration Is an Overlooked Problem Offshore Unlike factory installations on stable concrete floors, marine chillers often operate under constant vibration caused by engines, waves, and platform movement. Over time, vibration may loosen piping connections, damage support brackets, or increase mechanical wear.   In real marine installations, poor piping support design can sometimes create more long-term reliability problems than the refrigeration system itself. Because of this, marine chillers often require reinforced internal structures and vibration-resistant installation methods.   Common Marine Chiller Applications Today, marine chillers are widely used in: Ship engine cooling systems Offshore drilling platforms Hydraulic equipment cooling Seawater desalination projects Seafood processing plants Coastal chemical facilities Marine battery cooling systems Different projects require different cooling capacities, anti-corrosion levels, and voltage standards, which is why customized solutions are becoming increasingly common in the marine industry.   As a professional manufacturer, Hengde supports OEM and ODM marine chiller solutions based on customer installation space, operating conditions, and environmental requirements.   FAQ FAQ 1: Can marine chillers use seawater directly? Yes, but special materials are usually required. Standard condensers may corrode quickly when exposed directly to seawater. For seawater cooling applications, titanium heat exchangers or specially treated corrosion-resistant condensers are commonly recommended.   FAQ 2: Do marine chillers require more maintenance? Generally, yes. Marine environments are naturally harsher than indoor industrial environments. However, properly designed marine chillers can still maintain long-term stable operation if operators regularly: Clean heat exchangers Check anti-corrosion coatings Inspect electrical connections Remove salt buildup Monitor refrigerant conditions Preventive maintenance is especially important for offshore equipment because emergency repairs at sea are significantly more expensive.   Real Project Case: How Hengde Helped a Maldives Customer Solve Fishing Vessel Cooling Problems Hengde worked with a customer from the Maldives who operated several local fishing vessels. The customer originally used conventional industrial chillers purchased through a local supplier, but after less than a year of operation, multiple problems began appearing.   The biggest issues included: Severe corrosion on condenser fins Frequent electrical alarms during humid weather Unstable cooling performance after continuous operation Rust around piping connections and mounting structures   Because the vessels operated in high-salt seawater environments almost every day, the standard chillers simply could not withstand the local conditions. After discussing the operating environment with the customer, Hengde redesigned the system specifically for marine use. The upgraded solution included: Enhanced anti-corrosion protection More suitable condenser materials for coastal operation Reinforced electrical cabinet sealing Improved vibration resistance for onboard installation More stable temperature control during continuous sailing operations   For marine applications like fishing vessels, space is always extremely limited. In many cases, the design of a marine chiller has to be significantly more compact than land-based industrial chillers. This is not just an aesthetic choice — it is a practical requirement driven by ship layout constraints, where every cubic meter of space directly affects storage capacity and operational efficiency. After the new marine chillers were installed, the customer reported much more stable operation during daily fishing activities, especially during long working hours in tropical weather conditions.   For marine projects, real reliability does not come from having the most complex system. It comes from understanding how offshore environments and vessel limitations gradually affect equipment design — and optimizing the system from the start around those realities.
