3/4HP R134a single phase compressor

Its main application is new plants for medium and low refrigeration temperatures. The theoretical cooling capacity is 5% lower than the R-502 at evaporation temperatures equal to -40ºC. The coefficient of performance (COP) is between about 5 and 8% less than with R-502. If overheating increases, the R-404A COP may be higher than that of R-502. In the case of the retrofits of R-502 and its HCFC substitutes (R-408A, DI-44), it is necessary to eliminate 95% of original mineral oil or alkylbenzene, replacing it with an oil based on polyol esters, change the dryer filter, expansion valve, rubber O-rings with plastic ones and in some cases oversize the condenser. If it is used as an R-22 retrofit, it will also be necessary to replace the safety valves and other calibrated elements according to the R-22 pressures.
