Refrigeration dryer DRYBERG RF39 , 2340 Nm3/h
How DRYBERG RF Works
Hot moist compressed air enters the Air-to-Air heat exchanger (1) where it is precooled by the dry air leaving the dryer. The refrigerant compressor (3) compresses the refrigerant gas and push it through the condenser (4) where it is condensed in high-pressure liquid. The refrigerant liquid then passes through a capillary/calibrated orifice (5) that meters it into the evaporator (2) as a low-pressure liquid. The microprocessor adapts the working cycle to the real working conditions by controlling through “impulses” the opening and closing of the solenoid valve (6). In partial load conditions only a small portion of the refrigerant flows through the calibrated orifice of the solenoid valve (7) to the compressor that therefore consumes less energy.
The precooled air enters the evaporator (2) where it is cooled to the required dew pointy the incoming refrigerant liquid that changes phase and becomes a low-pressure gas suitable to continue the process as it returns to the suction side of the refrigerant compressor (3). The cold dry compressed air then returns to the Air-to-Air heat exchanger (1) where it is reheated by the incoming air, to prevent sweating in your plant.
