PD Series Energy Saving Refrigerated Dryer

PD series refrigerated dryer is a new type of energy-saving refrigerated dryer, which is mainly promoted by Lingyu company. This series of products have the characteristics of environmental protection, clean, energy-saving, etc. It is made of stainless steel or aluminum alloy, which is not easy to rust; the whole series is made of environment-friendly refrigerant; the heat exchange efficiency is better than the traditional shell and tube dryer, and the energy-saving effect is obvious.

Lingyu PD series refrigerated dryer, through forced cooling to reduce the water content of compressed air, to provide users with dry and clean compressed air. The lowest pressure dew point is 2 ℃. It adopts the three in one design of heat exchanger, evaporator and gas-liquid separator, plate-fin structure with high-efficiency heat exchange, microchannel condenser, refrigeration system uses refrigeration compressor with lower energy consumption, and the whole series adopts environmental protection refrigerant, so the whole machine is energy-saving and environmental protection.


Features of the Refrigerated Dryer

A. High-end refrigeration system configuration

  • Adopting Panasonic, Copeland, Danfoss, etc. international well-known brand compressors, which can ensure strong and continuous refrigeration compression capacity under long-term and high-intensity harsh environments.
