REFRIGERANT GAS R600A (6.5KG/CAN) GENERIC BRAND
Quantity: In Stock
As a refrigerant, isobutane poses a fire and explosion risk in addition to the hazards associated with non-flammable CFC refrigerants. Substitution of this refrigerant for motor vehicle air conditioning systems not originally designed for isobutane is widely prohibited or discouraged. R600a (isobutane) is refrigerant grade isobutane used as a replacement for R12 and R134a in a variety of high-temperature refrigeration applications.
R600a (isobutane) is a hydrocarbon that is becoming increasingly popular due to its low Global Warming Potential (GWP). It is the refrigerant of choice for domestic and light commercial refrigeration units, including fridges and freezers, drink dispensers and standalone display units.
