Rapport 2414173 - October 2007 __________________________________________________________________ The RKX26/31 semihermetic compressor takes advantage of a new design with 6 radial pistons. This enable a slimmer version than the HGX2 series. The motor is gas cooled in 2 or 4- pole version (3000/1500 rpm – maximum speed of 3600 rpm). With a swept volume of 31 cc, it enables a displacement volume of 2.60 m3/hr to 6.70 m3/h. This compressor can be mounted both in horizontal and vertical positions. It uses Bock C120E (Synthetic Oil), has an integrated oil separator and HP/LP safety valves. Danfoss offers small displacement volume compressors (see Figure 23), with capacity ranging from about 500 W to 2 kW. Figure 24 shows the claimed performance for the product range. The size is about the same as those used in domestic refrigerators, i.e. from 1 to 3 cc displacement volume. These compressors are used in some of the Coca Cola vending machines refrigeration cassettes.
