GAS R404A
Unlike alkyl halide refrigerants that contain bromine or chlorine, R-410A (which contains only fluorine) does not contribute to ozone depletion and is therefore becoming more widely used, as ozone-depleting refrigerants like R-22 are phased out.

THE RECHARGEABLE CYLINDER REMAINS OF YOUR PROPERTY
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 COP of the R-404A may be higher than that of R-502. In the case of 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. In case it is used as a retrofit of the R-22, it will also be necessary to replace the safety valves and other calibrated elements according to the pressures of R-22.
