Air Dryers

BURAN Refrigeration Compressed Air Dryers

Complete compressed air drying system with electronic level controlled condensate drain, dew point indicator, metal housing, power plug. The aluminum heat exchanger includes three functions in one: air-to-air heat exchanger, air-to-refrigerant heat exchanger and water separator.

DC 0020 AB - DC 0850 AB

The compressed air is being fed into the dryer and being pre-cooled in the air-to-air heat exchanger by the outgoing cold compressed air. The pre-cooled air then passes through the refrigerant-to-air heat exchanger where it is being further cooled down to the required pressure dew point. The moisture in the compressed air condenses out and gathers and discharges automatically. Finally, the cold discharged air is being reheated by the incoming compressed air. This saves energy and prevents any moisture forming beyond the dryer in the compressed air system. The cooling capacity of the refrigerat ion cycle is being control led by a hot gas bypass which assures the dryer functionabilty for partial loads, too.

Features

• Aluminum heat exchanger
• High overload capacity to a pressure dew point of approximate +20°C
• Electronic level controlled condensate drain
• All dryer in metal cabinet construction
• Lightweight & compact design
• Potential free alarm signal
  

Benefits

• No corrosion inside the heat exchanger due to contact with wet compressed air
• In case of overload, the dryer will only switch off at a dew point above than approximate +20°C
• No compressed air losses due to condesate removal, therefore reduction of operating costs
• Optimum protection against mechanical damage and against dirt
• Minimum space requirement (on stock, for transport and for the installation in the compressed air network)
• Economical operation and safe system installation in the compressed air network
