Air-cooled condenser is mainly used in air-cooled water chillers. It uses air as cooling medium. Because there are often dust or other sundries in the air, some of these dust or sundries will fall on the outside surface of the condenser fins. Over the years, the cooling effect of the condenser will become worse, especially in the bad environment. Therefore, we should clean regularly.The cleaning method of air-cooled water cooler condenser is: pure dust can be washed clean by compressed air or...

Why does the heat transfer oil control system device heat transfer oil coke exist?
In the heat transfer oil control system device, the heat transfer oil is used for the cooling and heating temperature control. If it is not the same as the LNEYA, the use of the fully closed circuit can affect the formation of certain coking, resulting in failure. In the heat transfer oil control system device, three main chemical reactions occur in the heat transfer process: thermal oxidation reaction, thermal cracking and thermal polymerization. Coking occurs from thermal oxidation reaction...

What should I pay attention to when placing high and low temperature closed loop circulators?
There are certain differences in the size and performance of high and low temperature fully enclosed circulators from different manufacturers. Users need to pay attention to the placement position when placing them after purchase. If the placement position is not good, it is not conducive to the operation of high and low temperature fully enclosed circulators. In the installation of high and low temperature fully enclosed circulators, the heat dissipation efficiency of the high and low temper...

Ultra-low temperature bearing cooling equipment Shrink Fit Bearings and Bushings and Pins
For the metallurgical industry, the oil pressure system of precision machine tools must use refrigeration to control the oil temperature to stabilize the oil film viscosity so that the machine tool can work normally. If applied to steel products, steel can be processed at low temperatures to improve its performance, increase its hardness and strength, and extend its use. life. Years ago, cutting tools were cryogenically treated by immersing them in liquid nitrogen. This subjected parts to the...
