Ambient air pumped in by a compressor always contains water vapour to some degree, depending on temperature and relative humidity. When this air is compressed, the volume reduces proportionally, but all the water vapour content remains. When the temperature falls to a value where the air becomes saturated, the humidity starts to condense; this is known as the dew point. With an effective final refrigeration stage, which causes a significant lowering of the temperature of the air delivered by the compressor, around 60-70% of the water content condenses out. The remaining 30-40% can be eliminated by installing a FRIULAIR dryer.
A complete range of refrigeration compressed air dryers covering flow rate from small to very large. -> Select Series Series AMD Series ACT Series PLS Series DFE Series TDF Makes the most of manufacturing and functional advantages of brazed plate heat exchangers, which are more suitable for high pressure working conditions. Two different refrigeration dryers with integral aftercoolers. -> Select Series Series AHT Series ADE Are dedicated to specific manufacturing divisions, where it is necessary a compressed air temperature equal to DewPoint, as injection moulding industry or food cold pressing process, etc. Compact heatless dryers with pressure DewPoint of down -70°C. Three different ranges with each with four filtration grades with drain and pressure drop indicator options. -> Select Series Series FT Series LF Series FW Airblast aftercoolers supplied with centrifugal condensate separators to pre-cool compressed air and remove some moisture. High efficiency centrifugal separators without moving parts for condensate removal from compressed air streams. Timed solenoid, float operated or intelligent zero loss drains to suit all applications. -> Select Series Timed Float Electronic level
