POLAR REFRIGERATED COMPRESSED AIR DRYERS - The inlet-air temperature can reaches 80°C. - The cooling-evaporator adopts the erect-circle spin constructure and a large scale area which make the pressured air stay a long time in the evaporator, ensure heat changing fully, congeal more water and keep a best drying effect. - dew point: 2°C-10°C - The pre-cooling/heat-changing of the system reduces about 50% of the load of the freezing system. - It reclaims the energy of the system by using the heat-changing at the evaporator and the outlet. This may reduce the load of the evaporator, remove the phenomenon of dewing and can ensure the safety of the system. - Provide air compressor from 5HP to 500HP(0.47m3/min-100m3/min).
