Compact Designed Air Refrigerated Dryers have the feature that the saturated compressed air pre cooled in the pre cooler/ reheated by the out going cooled dry air with out any additional energy requirement and the inlet air is further cooled in the evaporator to the required dew point and ensures that the cold air is then reheated when it passes back through the pre cooler/ re heater. The Dryers has load handling capacity of 0 to 100% without freezing and controls for constant evaporating and condensing temperature. The Dryers have the feature of easy in installation, operation, and low maintenance and easy to service. The Dryers have constant dew point and are eco friendly in nature. The Dryers consumes less energy and are offered in compact design. The Compact Designed Air Refrigerated Dryers are capable of providing non-cyclic operation and can be availed in various air/ water cooled models.
