Refrigeration Dryers

Buran Refrigeration Compressed Air Dryers

The Buran Refrigeration Compressed Air Dryers are suitable for volume flows up to 1,650 m³/h. They are available in 4 sizes. Sizes I to III represent a compact plug & play solution with integrated pre- and post-filters in a robust metal housing. Filters and condensate drains are more accessible considerably facilitating installation, maintenance and replacement. The flow-optimized pre- and post-filters with condensate drains in combination with the refrigeration compressed air dryer ensure that a compressed air quality of classes 2-4-2 can be achieved according to ISO 8573-1.

The proprietary design of Boreas heat exchangers incorporates large flow channels for low pressure drop, which translates into low operating costs. A built-in cyclone separator with our Ultramat® zero-loss drain valve allows for the removal of condensed water without wasting any compressed air. The space-saving design brings cooling air in the front and out the top, allowing the unit to be placed next to a wall with other equipment on either side. All Boreas dryers utilise environmentally friendly R-134a refrigerant and are available in either air- cooled or water-cooled configurations. Volume flows of 1.800 to 28.500 m³/h are covered by the Boreas series.

Bora DHP High Inlet Pressure Dryers

Bora DHP dryers can accept compressed air at inlet pressures up to 50 bar in ambient temperatures up to 50 ºC. The maximum inlet temperature is 60 °C. They utilize a two-stage heat exchanger for optimal heat transfer in the air-to-air and in the air-refrigerant head exchanger. Power consumption is reduced as less energy is required than conventional heat exchanger designs. Volume flows of 25 to 5.000 m³/h are covered by the Bora series.

Brisa SE High Efficiency Dryers

Brisa SE heat exchangers for compressed air have been optimised for extremely low pressure differentials. The Brisa SE dryers are suitable for volume flows of 10.500 to 50.000 m³/h. All Brisa SE dryers have up to a four-stage capacity control system for the refrigerant compressor and are serially equipped with a microprocessor controlled monitoring system. The overflow operation of the refrigerant vaporiser guarantees for a very good standard characteristic.
