Refrigeration dryers with Energy Saving Impulse Technology and Thermal Mass
With the introduction of RF, the new generation of energy-saving refrigeration dryers, BERG not only renews its product offering for the compressed air treatment but also reinterprets the concept of thermal storage operation, that made the international success of the RF dryers. The new Impulse Technology offers important advantages in terms of energy saving, reliability and operating costs as the RF dryer is able to adapt itself to the real needs of the compressed air system. The regulation system of the dryer controls the dryer operation granting the most energetically effective method of compressed air drying, achieving high energy saving and ensuring at the same time an excellent dew point stability also in dynamic conditions.
IMPULSE TECHNOLOGY FOR HIGH/MEDIUM AIR FLOWS
The refrigerant compressor is permanently ON to achieve a perfect control of the dew point. The microprocessor controls through “impulses” the opening and closing of a solenoid valve installed on the suction pipe of the refrigeration compressor, in partial load conditions then only a small portion of the nominal refrigerant flows through a by-pass calibrated orifice of the solenoid valve to the compressor. In partial load conditions the compressor compresses less refrigerant than at peak load and therefore it consumes less energy (refrigerant flow control technology).
THERMAL STORAGE OPERATION FOR LOW AIR FLOWS
The refrigerant compressor cycles ON/OFF for maximum savings and reliability. Since the refrigeration capacity is greater than the load, the excess capacity cools the all-in-one exchanger that acts like a thermal storage.• For high/medium flows, the dryer applies the Impulse Technology to regulate its drying capacity.
• For low air flows, the dryer utilizes the “thermal storage” operation.
