Chiller

In the current market environment, with the continuous expansion of the chiller/refrigerator market, numerous small and micro chiller manufacturers have emerged. However, some of these manufacturers are limited by their scale and R & D and production capabilities, resulting in poor overall quality of the chillers they produce. These chillers often fail to meet the actual needs of enterprises, manifested in issues such as insufficient cooling capacity, frequent equipment malfunctions, high maintenance costs, and lack of after - sales support.   For enterprises making their first chiller purchase, it is crucial to clarify their procurement goals and understand the industry situation. They should strive to obtain chillers with high cost - effectiveness at the lowest possible budget. Based on years of experience in serving customers, Hengde offers the following strategies for enterprises in the industry to control chiller procurement costs.   I. Look Beyond Price: Focus on Cost - Effectiveness Cost - effectiveness is also a key consideration in the procurement of industrial equipment. Although price to some extent reflects product quality, a high price does not necessarily mean high value. When enterprises purchase chillers, they need to carefully review the price plans and component configuration lists provided by suppliers. Take the chiller compressor as an example. In addition to paying attention to its configuration and industry ranking, the overall supporting scheme of the entire unit should be comprehensively considered. Even if the compressor has excellent configuration, if inferior materials are used for the water pump and condenser, the overall scheme may seem high - end and expensive, but in actual use, it may still cause many problems. Therefore, enterprises should make professional selections based on their actual needs and pursue the maximum cost - effectiveness.   II. Attach Importance to the Selection of Key Components such as Compressors As the core component of a chiller unit, the compressor's performance directly affects the operation of the unit. Improper selection may lead to problems such as unstable cooling and excessive noise, seriously disrupting enterprise production. Some chiller manufacturers use inferior or refurbished products for key components like compressors to reduce costs. This not only reduces the unit's efficiency but also significantly increases energy consumption. Hengde brand chillers always adhere to the principle of quality first. They use high - quality imported brand compressors such as Bitzer, Panasonic, and Hanbell, and are equipped with electronic control systems from well - known brands like Siemens, ensuring the quality of core components from the source.   III. Customize Procurement Plans Based on the Enterprise's Actual Situation Currently, chillers are developing towards personalization and non - standardization. Enterprises should select chillers based on environmental factors such as climate, temperature, humidity, and dust in the region where they are located. For example, when purchasing in arid regions, local special climate conditions need to be fully considered. In addition, the operating environment is also an important consideration. For chillers operating in a humid environment, products with stainless - steel shells can be preferentially selected; for scenarios with special working medium requirements, evaporators and condensers with anti - corrosion functions should be used. Through customized selection, enterprises can obtain chiller equipment that best meets their needs.   In conclusion, when enterprises purchase chillers, they should comprehensively consider multiple factors such as cost - effectiveness, the quality of core components, regional environment, and usage scenarios. Hengde suggests that enterprises fully compare the plans of different suppliers during the procurement process, make decisions based on their actual situation, and actively communicate with industry experts to obtain the optimal industrial chiller solution.   Choose Hengde, Choose Perfect Chillers!

Hengde Company, a renowned leader in the industrial refrigeration sector, offers top - notch Industrial Chillers that are crucial for various industrial processes. To ensure the optimal performance and long - term reliability of these chillers, proper installation is of utmost importance. Before commencing the installation, the following preparations are essential.   Pre - installation Preparations 1. The chiller unit should be installed in a dedicated machine room. Measures must be taken to exhaust the heat generated during the chiller unit's operation from the machine room. The ventilation volume should be sufficient to maintain the room temperature below 40°C.   2. The chiller unit should be installed on a non - deformable rigid base or a concrete foundation. This foundation should have a flat surface and be capable of bearing the weight of the chiller unit during operation.   3. There should be drainage measures such as drainage ditches around the chiller unit's foundation with sufficient discharge capacity. This is to facilitate the discharge of water in the system during seasonal shutdowns or maintenance.   4. The machine room should have enough space for the installation, maintenance, and repair of the chiller unit. There should be sufficient space for tube extraction. Also, no pipelines or wire ducts should be laid above the compressor.   5. To ensure the normal operation of electrical components, do not install the chiller unit in places with dust, dirt, corrosive fumes, or high humidity. If such conditions exist, they must be rectified.   Installation Requirements 1. For water-cooled chillers, select a cooling tower that matches the refrigeration capacity of the chiller. When installing the piping of the chiller, install it according to the diameter of the cooling water pipe. Do not reduce the size of the cooling water pipe, as this will cause high - pressure overload, affect the refrigeration effect, and increase power consumption.   2. For air-cooled chillers, they must be installed in a space more than 1m away from the wall to avoid poor heat dissipation, which can lead to high - pressure overload, affect the refrigeration effect, and increase power consumption.   Notes 1. For power load and grounding parts, please construct according to relevant regulations! 2. The chilled water pipes of newly installed chillers must be insulated!   Hengde Company is committed to providing not only high quality Industrial Chillers but also comprehensive technical support and after - sales services.

With the continuous advancement of technology, industrial chillers have found increasingly widespread applications in various industrial fields. They play a crucial role in ensuring the efficient operation of industrial production and enhancing product quality. However, as mechanical equipment, industrial chillers are inevitably prone to certain issues during long - term operation. One of the common problems is equipment corrosion. To effectively prevent the corrosion of industrial chillers and extend their service life, Hengde Company elaborates on the six major common causes of chiller corrosion and provides corresponding preventive measures.   1. Corrosion Issues Caused by Unreasonable Engineering Construction, Design, and Installation Some factories, especially when selling ordinary industrial chillers, cut corners to reduce costs and neglect essential anti - corrosion and anti - rust treatments. Once customers expose the chiller to the outdoor environment for an extended period, the equipment shell is highly susceptible to corrosion. This corrosion risk resulting from the neglect of anti - corrosion measures in the early construction and installation stages can severely affect the normal operation and service life of the chiller.   Preventive Measures: When purchasing equipment, choose suppliers with good reputations and quality guarantees to ensure that the chiller has undergone comprehensive anti - corrosion and anti - rust treatments before leaving the factory, such as spraying high - quality anti - corrosion paint and using corrosion - resistant materials for the shell. Before installation, assess the installation environment and avoid placing the equipment in humid, dusty, or corrosive gas environments. If outdoor installation is unavoidable, build a protective shed to shield the equipment.   2. System Pipeline Corrosion Caused by Incorrect Installation or Abnormal Operation of the Water Processor In water cooled chillers, the cooling water pipeline is a key passage for cooling water circulation. The quality of the water directly determines whether scale and rust will form in the system pipelines. If the water processor is installed improperly or operates abnormally, it cannot effectively treat the water quality, thereby triggering pipeline rust. This not only reduces the heat exchange efficiency of the chiller but may also lead to pipeline blockages, affecting the stable operation of the entire system.   Preventive Measures: Before installing the water processor, strictly follow the product manual for correct installation and conduct debugging after installation to ensure its normal operation. Regularly maintain and service the water processor, checking whether all its functions, such as filtration, sterilization, and descaling, are normal. Meanwhile, regularly test the cooling water quality and adjust the operating parameters of the water processor or replace consumables like filter elements in a timely manner according to the water quality conditions.   3. Insufficient Filtration of Fine Impurities by Y - type Filters Currently, the commonly used dirt removers in industrial chillers are mostly Y - type filters. They have the advantages of easy installation and convenient dirt cleaning and can conduct preliminary rough filtration of mechanical impurities, iron filings, and sand grains. However, their filtration effect on tiny impurities is unsatisfactory. As the unit operates for a long time, the condenser is extremely likely to accumulate dirt, sludge, and other impurities. These deposits not only reduce the heat transfer performance of the condenser but may also accelerate the equipment's corrosion process due to the formation of a local corrosion environment.   Preventive Measures: Based on the Y - type filter, add a precision filter to conduct more refined filtration of tiny impurities. Regularly clean and maintain the Y - type filter and the precision filter, and promptly remove the impurities inside the filters. At the same time, regularly clean the condenser. Chemical cleaning or physical cleaning methods can be used to remove the dirt and deposits inside the condenser and maintain its good heat transfer performance.   4. Absence of a Quick Drain Valve in the Chilled Water System The quick drain valve plays an important role in draining in the chiller or chilled water system. It has a simple structure, good sealing performance, small size, and light weight, and is especially suitable for regular draining of the system. It also has the advantages of corrosion resistance, impact resistance, and long service life. However, currently, many industrial chiller end plates in enterprises do not have a quick drain valve installed, which is likely to cause system pipeline corrosion. During the daily operation of the chiller, it is recommended to open and close the drain valve three times a week to ensure smooth system drainage and maintain the good operation of the system.   Preventive Measures: For chilled water systems that have not installed a quick drain valve, install a quick drain valve that meets the system requirements as soon as possible. In daily use, strictly follow the recommended operation frequency to open and close the drain valve to ensure that impurities and dirt in the system are discharged in a timely manner. At the same time, regularly check the sealing performance and working status of the drain valve and replace it promptly if it is damaged.   5. Absence of a Water Meter in the Cooling System Makeup Water Pipeline In the water quality treatment process of the cooling system, chemicals and bactericides are usually used to kill fungi, microorganisms, and remove various dirt inside the pipeline. The dosage of the chemicals needs to be accurately adjusted according to the makeup water volume and the system water volume. If there is no water meter installed in the cooling system makeup water pipeline, it is impossible to accurately measure the makeup water volume, resulting in inaccurate chemical dosing. Excessive dosing may cause chemical corrosion of the pipeline, while insufficient dosing cannot effectively inhibit the growth of microorganisms and the formation of dirt, also triggering system pipeline corrosion problems.   Preventive Measures: Install a water meter with appropriate accuracy in the cooling system makeup water pipeline to accurately measure the makeup water volume. According to the system water volume and makeup water volume, accurately calculate the dosage of the chemicals according to the chemical usage instructions. At the same time, regularly test the water quality of the cooling system and adjust the dosage and type of the chemicals in a timely manner according to the test results to ensure that the water quality is in a good state.   6. Corrosion of the Equipment Surface by Acidic and Alkaline Gases in the Environment During factory production, some special gases, such as acidic and alkaline gases, are inevitably generated. These gases flowing in the environment can cause erosion damage to the equipment surface. Therefore, when selecting a chiller in an environment with such special gases, it is necessary to explain the situation in detail to professionals in advance so that explosion - proof and corrosion - resistant materials are preferentially selected for the production of the electrical control box or evaporator pipeline. This can effectively prevent the equipment from being corroded and damaged by acidic and alkaline gases during the later operation.   Preventive Measures: During the equipment selection stage, fully consider the gas components and concentrations in the working environment and choose chillers with corresponding protection levels and corrosion - resistant properties. For installed equipment, gas purification devices can be set up around the equipment to reduce the concentration of acidic and alkaline gases in the environment. Regularly inspect and maintain the equipment surface. If there are signs of corrosion, promptly carry out repair and protection treatments, such as repainting anti - corrosion paint.     With the rapid development of industry and the continuous emergence of new materials and new processes, the application scenarios of industrial chillers are becoming increasingly diverse, which increases the risk of equipment corrosion. Here, Hengde earnestly reminds industry friends that for industrial chiller equipment, real - time maintenance and customized servicing remain the keys to reducing corrosion and extending the service life. Only through scientific and reasonable maintenance measures can industrial chillers operate continuously and stably in complex industrial environments and provide reliable support for industrial production.
