Technical Data Sheet Page 1 of 3 Aftercooler for compressed air and gases UFK-W, water-cooled The aftercooler UFK-W is designed to cool compressed air, but can be used for other gases as well. Product description: Features: The Aftercooler can be delivered with fixed nest of boiler tubes as well as with moveable nest of boiler tubes. Furthermore all aftercoolers are equipped with a cyclone separator. The coolers consist of enlarged surface insertions made out of copper. The shell, the pipes and the flanges are made of steel. Technical Data Aftercooler: Radiator tube bundel Shell, pipes and flanges Surface finish Polyester resin coating resp. cathodic dip-coating Maximum operating pressure: 0100 - 5000 Maximum operating temperature: Air, inlet: Water, inlet: Separator: with fixed nest of boiler tubes for clean cooling water 0450 Z-10500 Z with moveable nest of boiler tubes for dirty cooling water Annotation: The flow capacity is related to a compressed air volume flow (at 1bar, 20°C) at 7 bar pressure, an air cooler inlet temperature of 120°C and an air cooler outlet temperature which is 10°C higher than the cooling water inlet temperature. F119091_06_2018_ENG The UFK-W as an additional piece of equipment after the compressor supports an efficient and economical purification of compressed air. The cooler works in a counterflow procedure where the hot compressed air is cooled down by eliminating heat over the cooling tubes to the cooling water. The generated condensate will be drained by a cyclone separator. This product series offers 9 different housings ranging from a volume flow of 100 to 5000 m3/h with fixed nest of boiler tubes and 9 different sizes for a volume flow of 450 to 10500 m3/h. with removable nest of boiler tubes (related to 7 bar g).
