Boge DS-2 series refrigerant dryers

Boge says its DS-2 series refrigerant dryers are more environmentally friendly than their predecessors. They come with refrigerant R 513 A as standard, which has a lower global warming potential than the refrigerants previously used. They are also said to offer economic advantages, with a smart control system that adjusts to demand and reduces power consumption at a constant pressure dewpoint.

The smart control automatically switches off the cooling compressor at partial load as soon as the required dewpoint has been reached. The cooling temperature is stored in the heat exchanger, and this cold reserve cools the incoming compressed air until the dewpoint rises again. The cooling compressor only starts up again to maintain the required temperature level, and thus only begins consuming energy at this point. This principle allows energy savings of up to 79% compared to a dryer in continuous operation. The frequency-controlled fan provides a stable condensation pressure and reduces energy consumption by up to 25%. Additionally, the design of the heat exchanger combined with low differential pressures and a low refrigerant requirement results in lower power consumption.

The systems can be easily incorporated into an existing infrastructure due to various interfaces. Communication takes place by Modbus RTU, USB ports or optionally by Modbus TCP/IP.
