1 R407C compressors Semi-hermetic compressors for air-conditioning applications with R407C New: Now up to 35 bar high pressure, 74 C condensing temp. possible

2 Compressors for R407C 35 bar - At a glance At a glance Based on our currents semi-hermetic product range, with its outstanding advantages and features, there is now a compressor series available for the use with the refrigerant R407C with expanded fields of application. Those compressors are especially suited for the application in mobile air-conditioning systems, such as railway air-conditioning. The refrigerant R407C Besides R407C, R40A is also considered a long-term replacement refrigerant for R22. In addition, it is an alternative to R34a. Suitable refrigeration oils are ester oils, such as e.g. Fuchs Reniso SE55. Condensing pressures of up to 35 bar possible (approx. 74 C condensing temperature). Available models Displacement 50 Hz (.450 rpm) Special features To ensure the reliable operation of the refrigerant R407C in countries with high ambient temperatures of up to 50 C, Bock compressors for R407C are approved for a maximum operating pressure of 35 bar. This corresponds to a condensing temperature of approx. 74 C and opens up completely new possibilities for the use of this refrigerant.

Compressor application limits should not be chosen for design purposes or continuous operation. Restrictions to the operating limits may occur when using frequency converters. For further information see mobile catalogue. erformance data The performance data for R407C are based on the european standard EN 2900 at 50 Hz supply frequency. This signifies: 20 C suction gas temperature without liquid subcooling. Evaporation and condensing temperatures are based on the dew point values (saturated vapour conditions). This results in significant differences compared to specifications with liquid undercooling and/or suction-gas temperatures. Conversion factor for 60 Hz =,2 erformance data for other operating points, see Bock software. I 3
