BOGE DT refrigerant dryer series

The BOGE DT refrigerant dryer series have been designed for sustainability. Models in the range keep a constant dewpoint of 3°C at a free air delivery of between 0.4 and 14 m3/min and the products come with an ‘all-in-one’ aluminium heat exchanger operated in a reverse flow process and containing an air/air heat exchanger, evaporator and condensate drain. The R-513A refrigerant used means the models are compliant with Regulation EU 517/2014 on fluorinated greenhouse gases. The range’s refrigerant circuits are hermetically sealed.

As hot air is injected below a specific temperature, there is no chance of ice forming in the evaporator. The refrigerant dryer’s condensers are amply dimensioned, delivering good operation even for compressed air at an inlet temperature of 70°C. The large fan is mounted directly on the condenser for high cooling air flow.

The CCD 10 condensate drain has electronic level adjustment, so condensate that might form can be drained without pressure losses once a defined level has been reached. If the dewpoint is reached in partial-load operation, the control unit automatically switches off the compressor. The condensate in the heat exchanger then cools the compressed air until the dewpoint once again reaches the target value, allowing the cooling compressor to come back on.

The refrigerant dryer’s control system enables continuous monitoring of the pressure and temperature. The pressure dewpoint can be checked with the help of the LED status light. The models come with a Modbus RTU/RS 485 interface, allowing users to detect alarm thresholds and display other parameters and these data can be forwarded to an interlocking control device or master display for further use.
