  What are the main types of air-cooled chillers? Air cooled chillers  are divided into four main types according to their compressors, as follows: 1. Scroll air-cooled chillers. 2. Screw-type air cooled chiller. 3. Centrifugal air-cooled chiller. 4. Piston type air-cooled chiller. How to replace the air filter of the air-to-chiller? 1. Turn off the air cooled chiller. 2. Determine the exact location of the air filter. 3. Check its size with a new one. 4. Remove the access panel. 5. Remove the old air filter. 6. Insert the new air filter following the arrow guide. 7. Close the access panel and turn on the air-cooled chiller. Do air-cooled chillers need a cooling tower? No, it does not require a cooling tower. In air, a chiller dissipates heat into the surrounding air, so it is used in areas where heat is not an issue. What is the difference between an air-cooled chiller and a heat exchanger? Both are pretty much used to provide cooling, but are slightly different in design. Ai...

  Industrial chillers  consume a lot of energy, especially in hot weather, and they have to work harder to maintain the desired temperature. In order to achieve the purpose of energy saving, users of various industrial chillers in the enterprise can combine their own actual operating environment to choose a suitable energy-saving solution for industrial chillers to improve the overall operating efficiency. Help enterprises complete all production processes with higher capital. Here are some ways to reduce your industrial chiller’s energy consumption during hot weather: Optimizing Chiller Operating Conditions: Make sure your chiller is running at peak performance by regularly checking set points, temperature differentials, and water flow. Also, make sure the chiller is serviced and maintained regularly to avoid any inefficiencies. Install a Variable Speed Drive (VSD): A VSD can be installed on the chiller's compressor to ensure the chiller is only running at its required capaci...

  Industrial chillers   are assembled from multiple machines and equipment such as condensers, evaporators, compressors, etc. The water chiller is widely used in plastics, electroplating, electronics, chemicals, pharmaceuticals, printing, food processing and other industrial refrigeration processes that require the use of chilled water In this field, the normal operation of the chiller is essential for daily maintenance, so what are the common problems of the chiller? Next, the   H.stars   will answer for you. 1. Insufficient refrigerant Solution: The refrigerant needs to be supplemented until a sufficient amount, and the pressure is maintained at about 0.5MPa during refrigeration. 2. Due to climate reasons, the outdoor temperature is too high in summer, which causes the condensation pressure and temperature of the outdoor unit to be too high. Solution: It is necessary to improve the working environment of the outdoor unit of industrial water chiller, and restart the...

  The importance of traditional industries in our lives is becoming more and more obvious, and the importance of related equipment that assists traditional processing industries is also becoming more and more obvious.  Air-cooled chillers  have become an indispensable presence in the plastics processing industry. An excellent chiller can greatly improve the surface finish of the plastic products we see now, and can also greatly reduce the probability of marks, textures and internal stress on the surface of plastic products, ensuring that the plastic products that reach consumers will not shrink or appear. In the case of deformation, choosing an air-cooled chiller can also help more convenient demoulding and product molding when processing plastic products, which greatly improves the production efficiency and product quality of the industry. Air-cooled chillers have become an indispensable refrigeration auxiliary equipment for manufacturers in the plastics industry. Theref...

  1、   Introduction: With the implementation of the national strategy of developing the ocean, the use of petrochemical devices on my country's offshore platforms has developed rapidly.  Seawater heat exchanger  is an important equipment that is most widely used in offshore platform operations. The heat exchange status of the heat exchanger directly affects the smooth operation of the entire platform and the comprehensive economic indicators, and has a great impact on the safety, stability and long-term operation of production. It plays an important role. The selection of materials is a very important link in the design of seawater heat exchangers. Whether the selection of materials is appropriate has a great impact on the production, safety, maintenance and technical transformation of the device. For the selection of heat exchanger materials, the relevant standards and specifications should be strictly followed, and the best materials should be selected according to...

  Although most of the various   industrial chillers   produced in my country are imported compressors, which have a long service life, but in actual use, if the user does not carefully maintain and maintain the compressors of the industrial chillers, Different degrees of failures will also occur, seriously affecting the performance of the entire industrial chiller. There are several effective measures to prevent industrial chiller compressors from malfunctioning, including: Regular maintenance: Regular maintenance of the compressor, including cleaning and replacing parts, can prevent malfunctioning due to wear and tear.During the use of industrial chillers, it is necessary to pay attention to the noise of the compressor at all times. If the noise increases significantly, according to the experience introduced by the industrial cooler factory, it is necessary to complete the shutdown inspection in a timely and effective manner at this time to ensure normal operation. On t...

  As we all know , the society is urging all enterprises to fulfil their obligation on energy saving to keep the earth green for our next generations.
