  Ensuring the longevity of an industrial air cooled chiller involves a series of diligent maintenance practices designed to maintain optimal performance and prevent premature wear. Regular inspections and upkeep are critical for the efficient operation of these systems. For an   air cooled screw chiller , frequent checks of key components such as the compressor, condenser coils, and evaporator are essential. The compressor should be monitored for any signs of wear or inefficiency, like unusual noises or vibrations, which could indicate potential issues. Keeping the condenser coils clean is equally important, as dirt and debris can obstruct airflow and reduce the system's efficiency. Maintaining proper refrigerant levels is another crucial aspect of prolonging the life of an  industrial air cooled chiller . Low refrigerant levels can cause the system to overheat, potentially damaging the compressor and other components. Regular monitoring and replenishment of refrigerant ...

  Air-Cooled scroll chiller   VS   Air-Cooled Screw Chiller Functionally: The air-cooled screw chiller and the air-cooled scroll chiller have the same cooling function. The cooling, heating and energy are all electric energy. Application industry: are mainly used in industry, medicine, plastic, food, coal, shopping malls and other industries. It can be installed on the roof or outdoor courtyard, without the need for a dedicated machine room and cooling tower. The smallest air-cooled screw chillers are 30HP/30Ton, while air-cooled scroll chillers range from 1HP/1Ton to 60HP/60Ton. The two categories differ on the basis of capacity range. Another difference is that screw chillers do not have a built-in water tank and water pump, while air-cooled scroll chillers have a water tank and water pump. Furthermore, it has a compact design, so it is easy to integrate. Unlike screw chillers with touch screens, air-cooled scroll chillers are equipped with an easy-to-use PID controller...

  The compressor is the heart of the   chiller , and the normal operation of the compressor is the basis for the normal operation of the chiller. Therefore, if we want to understand the chiller, we must first understand the compressor. Today we will talk about the reasons for the internal protection of the semi-hermetic screw compressor. There is a thermal switch inside the screw compressor. The function of this switch is to disconnect the power supply circuit to the motor of the compressor when the temperature of the compressor exceeds the set value, and the compressor can not be turned on until the compressor is cooled down. And compressor Work. This is the internal protection of the compressor. Today we will talk about the reasons and solutions for this situation. 1.The refrigeration system is short of refrigerant. When the refrigerant is insufficient, the refrigerant returning to the compressor will be overheated, causing the compressor to heat up as a whole, causing the t...

 The  air-cooled chiller  is one of the chiller models. It cools the water at room temperature to a certain temperature through the compressor of the chiller to strengthen cooling of the mold or machine. It is used as a stand-alone machine. The heat sink is a built-in fan. There are three main mutual Linked systems: refrigerant circulation system, water circulation system, electrical automatic control system.   The air-cooled chiller is mainly used to cool the heating components of the equipment to ensure the normal operation of the equipment at a constant temperature. The air-cooled chiller is suitable for high-speed spindles, electric spindles, CNC machine tools, coordinate boring machines, grinders, machining centers, laser marking machines, laser engraving machines, laser welding machines, laser coding machines, laser cutting machines and other equipment. It is also widely used in the following industries. Injection rubber process: cast film, composite film, blow...

  It is understood that the   magnetic bearing chiller   is a new type of centrifuge equipment appearing in the international market. Compare to screw chillerIts main characteristics are fast speed, low noise, energy saving, intelligent management, in line with the trend of green development, and the magnetic levitation technology is in the world's leading level. Magnetic levitation  compressor . bearing sensors detect bearings 6 million times per minute . make sure that the maximum offset of the shaft does not exceed 7 microns Automatic control software can compensate vibration error automatically . bearings up to 48000 rpm, smaller size Only 2a-4a starting current has no impact on the power grid Centrifugal compressor, magnetic bearing without lubricating oil, variable frequency drive, integrated digital control. Magnetic compressor 9 characteristics 1.The unit controls the water temperature to an accuracy of ±0.1 °C, and the general unit temperature is ±1 °C. It c...
