Twin Tower Engineering RDH compressed air refrigerated dyers are designed to handle high inlet air temperatures (up to 210°F). Easy to install, these all-inone units eliminate the need for a separate aftercooler, moisture separator, and particulate filter.
INLET AIR TREATMENT Due to the geometric configuration of the heat exchanger, a filter of at least 1.0 micron is required. This will prevent fouling from rust, scale or other solid particulates pollutants, resulting in prolonged life of the RDH heat exchanger module.
“HOT GAS” BY-PASS VALVE An innovative design, new to the industry utilizes a thermostatic bulb to control suction pressure. This ensures dryer performance regardless of load conditions and eliminates freeze-up at low loads. Calibrated at the factory, the valve never needs adjustment in the field, resulting in simpler maintenance.
Maximum heat transfer is achieved in the air-to-air heat exchangers cross-flow design. The large surface areas coupled with the cross-flow of the refrigerant gases in the air-to-refrigerant exchanger ensure no liquid is returned to the refrigeration compressor.
Refrigerant Discharge
Refrigerant Inlet The maintenance free separator is located in the heat exchanger module. The highly efficient coalescing separator provides superior moisture separation. The large cross-section flow channel results in low velocities, producing low-pressure drop and reduced energy costs.
