How the refrigeration dryer works
Utilizing a closed refrigeration cycle with eco-friendly refrigerant R513A, the dryer cools the air to condense and extract moisture. Delivers a pressure dew point of +3 °C (ISO 8573-1:2010 Class 4).

Step-by-Step Process:

1. Compressed Air Intake Moisture-laden compressed air enters the dryer directly from the compressor.

2. Pre-Cooling via Heat Exchanger Incoming warm air is initially cooled by exchanging heat with already dried, cooler outgoing air. This increases overall efficiency.

3. Refrigeration Cooling Cycle The air then enters the refrigeration unit, where it is chilled using the eco-friendly refrigerant R513A. Lowering the temperature causes water vapor in the air to condense into liquid.

4. Moisture Separation & Drainage Condensate is collected by an integrated separator and discharged using an intelligent no-loss electronic drain, minimizing air loss, or timed drain (TD models)

5. Reheating Before Exit Before exiting, the air is reheated via the heat exchanger to prevent condensation and corrosion in downstream piping.

6. Smart Control System A programmable control panel regulates fan speed and monitors dew point, temperature, freeze prevention, and alarms — ensuring optimal performance and avoiding icing or faults.
