Boreas DV 1260 - DV 2 AB / WB Air cooled / water cooled Refrigeration Dryers PRODUCT DESCRIPTION MA FEATURES & BENEFITS Refrigeration compressed air dryer for safe and economical compressed air drying 17 sizes for nominal flow rates of 1.260 to 21.000 m³/h allow an accurate selection of the appropriate refrigeration compressed air dryer to the respective operating volume flow Hot gas bypass control in conjunction with pressure and temperature monitoring for safe operation and constant pressure dew point under different load conditions Electronic level-controlled condensate drain on the heat exchanger ensure reliable condensate drainage depending on the amount of condensate without loss of compressed air. Includes function monitoring and alarm message The electronic control including display shows the current pressure dewpoint, operating hours as well as service and alarm messages and offers numerous possibilities for individual adjustment Compact und space-saving design with robust steel housing Compression of the refrigerant at high running, low vibration and low noise operation For the energy-conscious user, the new Boreas DV refrigerators are now available. These compressed air dryers are designed for operating pressures up to 14 bar and thus cover a wide range of applications in various industries. The dew point is controlled by a hot gas bypass, which ensures a constant dew point even under different load conditions. The electronic control system in conjunction with pressure Controller Display and temperature sensors continuously monitors the operating conditions in the cooling circuit and indicates any alarm conditions on the control display or activates the potential-free alarm DUSTRIES contact. Both the air cooled and the water cooled version are equipped with an electronic-level-controlled condensate drain on the heat exchanger, which ensures a safe condensate drainage depending on the amount of condensate, without loss of compressed air.

PRODUCT DESCRIPTION Function Description (air cooled version) The warm, moisture-laden compressed air enters the air/ air heat exchanger (1a) and is precooled there by the incoming compressed air. The compressed air then flows into the air/refrigerant heat exchanger (1b). There, it is cooled to approx. 2 C, whereby water vapor is condensed and the liquid water is separated in the water separator (1c) and is discharged from the system via the electronically-controlled condensate drain (21). The cool, saturated compressed air then flows back through the air-to-air heat exchanger (1a) and is heated by the incoming compressed air and thus is under-saturated. The pressure dewpoint achieved depends on the design and operating conditions and is + 3 C at nominal operating conditions. In the refrigeration circuit, the refrigerant is compressed in the refrigerant compressor (6) and then liquefied with the fan (9) in the condenser (8). The liquid refrigerant is expanded via a capillary tube (11) and injected into the air/refrigerant heat exchanger (1b). The warm compressed air evaporates the refrigerant and the pressure is reduced and cooled by this phase change, which also cools the compressed air. The expanded and gaseous refrigerant is returned to the compressor. During those periods when the compressed air load is reduced the excess refrigerant is by-passed automatically back to the compressor via the hot gas by-pass valve (7).
