The characteristics determined by the partial pressure of water vapor in compressed air and the temperature of compressed air are used for cooling, dehydration and drying. While keeping the compressed air pressure basically unchanged, lowering the temperature of the compressed air can reduce the water content in the compressed air, and the excess water vapor will condense into liquid. The refrigerated dryer uses this principle to dry compressed air using refrigeration technology, so the refrigerated dryer has a refrigeration system. CMN has such perfect refrigerated air dryers for sale. CMN refrigerated air dryers for air compressor are not only efficient in the working process but also cost-effective. Please CONTACT US.
The high-pressure micro oil screw air compressor crafted by CMN has an air supply pressure of 20 to 45 kg. The air end is lubricated with high-quality lubricating oil and has two stages screw compression air end, which can be adapted to most high-pressure compressed air supplies.
CMN oilless scroll-style air compressor has an air supply pressure of 2 to 12 bar, a gas production volume of 255 to 1660L/min, and an ultra-quiet design. As one of the best oil free compressor suppliers, CMN oilless scroll style compressor is suitable for various processes with small gas consumption but high cleanliness requirements. The main components of the unit are a high-precision square air end, permanent magnet motor, frequency converter, and stainless steel gas storage tank.
The working principle of the pure oil-free screw compressor is the same as that of the normal pressure oil-free screw air compressor. The difference is that the low-pressure screw air compressor is equipped with a low-pressure stainless steel air end with a compression ratio of 1.2 to 4, and the air supply pressure of the unit is 1.2 to 4 bar. The unit has good stability and low energy consumption.
