R-417A is a zeotropic three-component blend, which we recommend, be
transferred from the cylinder in the liquid phase. In any operational
leak scenario, the system may be topped up with R-417A without
significant effect on performance.
R-417A is an effective refrigerant for process cooling. R-417A has
demonstrated its effectiveness at higher temperatures, giving the added
benefit of lower discharge temperatures.
R-417A is a well-suited, proven refrigerant for cold store
applications. R-417A works well from margarine and fruit storage at
around +3ºC, to medium temperature storage at -30ºC. In many instances
lower compressor discharge temperatures have been reported which can be
a bonus where systems are running close to the recommended maximum.
