Removing Moisture Removes Risk

    During the compression process, the compressor turns humidity in the intake air into condensate. ABAC’s range of COOL refrigerant dryers are designed to remove water from any compressed air system and pipework, even at high flow rates, minimizing the risks of corrosion and equipment breakdown. It is crucial that process air is consistent in all applications, all year round. By ensuring an ABAC dryer is correctly matched to your system, you can have peace of mind with low servicing costs, without compromising air quality.

Refrigeration dryers use a refrigerant gas in order to cool the compressed air. As a result the water from the air condenses and can be removed. With this technique we can reach in the COOL range a pressure dew point of 41°F. As a result, the refrigeration technology is by far the most used dryer technology, complying for more than 95% of industrial applications. Refrigerant dryers are commonly used with pneumatic applications and in the general industry (e.g. engineering, steel, paper, tannery, garage).


ABAC COOL dryer with labeled components

1. Capillary Tube in order to considerable reduce the pressure & temperature of the refrigerant, improving the cooling process.

2. Refrigerant Filter in order to protect the capillary from possible dirty particles.

3. Hot Gas By-Pass Valve:

  • Injects hot gas from compressor discharge into suction/liquid separator
  • Keeps refrigeration capacity in all load conditions
  • Maintains constant pressure in the evaporator, avoiding freezing.

 4. Timer Drain ensures a proper drain of the condensate.

5. Control Panel: PDP indicator (green zone) & main on-off switch.

6. Air/Air & Air/Refrigerant Heat Exchange with high thermal exchange and low load losses. Integrated water separator allows a highly efficient water-air separation.

7. Refrigerant compressor driven by an electric motor, cooled using refrigerant fluid and protected against thermal overload.

8. Refrigerant condenser air-cooled and with a large exchange surface for high thermal exchange.
