Compressed Air Dryers

A microprocessor based control device is an advanced solution for drying compressed air. Compressed air is fed into the dryer and precooled in the air-to-air heat exchanger by the cold compressed air. The pre-cooled air passes through the refrigerant-to-air heat exchanger where it is further cooled to the required pressure dew point. The moisture in the compressed air condenses and is collected and discharged automatically. Finally, the cold discharged air is re-warmed by the incoming compressed air. This saves energy and prevents any moisture from forming downstream of the dryer in the compressed air system.

Advantages at a glance :

• Multi-functional display
• Load controlled energy consumption; reduction down to 10% of nominal energy consumption
• Load controlled drain
• Low voltage monitoring
• Optional dry contact for alarm signal and analog signal 0-10 V for dew point temperature
• Maximum operation parameters: inlet temperature 60° C, ambient temperature 50° C for the whole series
• One component refrigerant R 134a, ozone factor zero
• Compact and easy to install cabinets

Purifying compressed air on demand, free of particles and condensate, helps decrease running costs. Equipment consisting of integrated pre- and after-filters and an electronically level-controlled drain ensure pure, dry and oil-free compressed air with no loss of compressed air from condensate drainage. Economical drying is guaranteed by an integrated microprocessor, which controls the adsorption and regeneration cycles. Heat regenerative driers can be offered with the following options:

• Explosion proof version
• Pressure dew points of -70° C
• Steam regeneration systems and dryers for higher pressures and higher flow rates
• All functions, sequences, operating states and faults are displayed by LEDs on flow charts and they are monitored continuously
• Control of the air recovery temperature
