Old customer in Australia, customer inquire about compressor cooler 5.6904 and 5.6911E1 50 units of each. Regardless of whether the cooler adopts air cooling or oil cooler, the working principle is the same. The fins of the air-cooled cooler are easily covered by dust and affect the cooling effect. The exhaust temperature will be too high and cause the machine to jump. Therefore, it is necessary to pay attention to the cleaning of the cooler in the maintenance. When it is blocked, it must be cleaned by a special liquid soaking method to achieve the real effect of removing impurities.The function of the cooler is to ensure that the entire air compressor is not in a high-temperature working state, reduce the temperature of the entire machine, and ensure that the operating temperature of the air compressor tends to a stable range. 

Our AIDA cooling system adopts high-efficiency heat exchanger, which is a special heat exchanger for high temperature and high humidity environment. The heat exchange area is increased by more than 30%, and the well-known brand low-noise cooling fan is selected, which is energy-saving and efficient. This special coolant for air compressors also has the characteristics of low pour point and high viscosity index, and can be used in winter and summer.This customer is the end-user. He has the big demand on the compressor coolers. We produced one unit as sample for him last month. He was satisfied with the compressor cooler performance. So we confirmed the new proforma invoice soon. The goods are under production now.
