Series Energy Saving Cycling Dryers

90-675 SCFM

CCE Series Dryers automatically cycle (on/off) the refrigeration compressor in response to inlet load conditions. As the inlet air load is reduced, the power requirement to dry the air is matched in proportion to the demand resulting in lower power costs.

CCE Series Dryers are built with an energy saving process.

The Drying Process-Compressed Air Circuit

1. Warm, saturated compressed air enters the dryer through the inlet pipe connection.
2. Air travels through the air-to-air heat exchanger and the glycol-to-air heat exchanger. Propylene glycol surrounds the passages and cools the air to the desired pressure dew point.
3. Moisture, solid particulates and oil aerosols are removed by the filter/separator.  A no-air-loss condensate drain discharges contaminants from the system.
4. Dry, filtered air exits the dryer for use.

The Cooling Process-Glycol Circuit

1. Glycol exits the air-to-glycol heat exhanger and then enters the glycol storage tank.
2. A circulation pump continuously moves the thermal medium throughout the circuit.
3. A thermal sensor monitors the glycol temperature and turns the refrigeration compressor off whenever the glycol is cooled to its lowest temperature. The cooling medium continues to dry the air. After the medium warms up, the thermal sensor restarts the refrigeration compressor.
4. The glycol-to-refrigerant heat exhanger chills the thermal media and travels back to the air-to-glycol heat exchanger.
