BOGE DT refrigerant dryers

BOGE has expanded the DT series of refrigerant dryers with features including a frequency-controlled cooling compressor and speed-controlled fan. The environmentally friendly range is designed to ensure operation is adapted to the actual requirement.

The established refrigerant dryers DT 4 to DT 140, designed for constant dew point of 3°C at a free air delivery of 0.4 to 14 m³/min, are now complemented with new models that provide a free air delivery of 18 to 75 m³/min. They are available as fixed-speed or frequency-controlled models and with water cooling as an option. A key component of the latest generation is the hermetically enclosed cooling scroll compressor which, from a flow rate of 18 m³/min, is also available as a frequency-controlled version (DT 180 F).

The DT series cooling scroll compressor allows operation that is low in vibration and noise. The frequency-controlled version flexibly adjusts energy consumption to the thermal load as well as flow quantity of the refrigerant and requires low start-up currents. Frequency control is designed so that, even when there is little demand, the drying capacity remains suitable and the pressure dew point is stable. Five operating modes allow individual configuration.

The refrigerant dryer also features a large display which shows all values clearly and enables maintenance cycles to be planned effectively.
