Boge Compressors BOGE DS-2 series refrigerant compressed air dryers

The refrigerant dryers from BOGE’s DS-2 series are designed to be more environmentally friendly than their predecessors. They come with refrigerant R 513 A as standard, which has lower global warming potential than the refrigerants previously used.

The series is also designed to provide economic advantages as the smart control adjusts to the actual demand and reduces power consumption at a constant pressure dewpoint.

For example, 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. 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 new frequency-controlled fan is designed to ensure a stable condensation pressure and reduce energy consumption by up to 25%. Furthermore, the patented design of the heat exchanger, combined with low differential pressures and a low refrigerant requirement, results in lower power consumption. The high-efficiency components reduce pressure losses to a minimum, which prevents over-compression.

With a GWP (global warming potential) of 573, the new devices exceed the requirements of F-Gas Regulation EU 517/2014 which stipulate a significant reduction in emissions of fluorinated greenhouse gases (F-gases) by 2030 to protect the environment. Furthermore, the models of the DS series require a small amount of refrigerant to begin with.

Thanks to the hermetically sealed refrigerant circuit and a CO₂-equivalent less than 10 t, the entire series is exempt from the leak tightness test stipulated in the F-Gas Regulation. So users can save the costs of testing by certified refrigeration technicians.
