Refrigerant gas R600a
Refrigerant gas R600a suitable for domestic refrigeration is a High purity Isobutane flammable gas replacement for R12.
Isobutane (i-butane), also known as methylpropane, is a chemical compound with molecular formula C4H10 and is an isomer of butane. It is the simplest alkane with a tertiary carbon. Concerns with depletion of the ozone layer by freon gases have led to increased use of isobutane as a gas for refrigeration systems, especially in domestic refrigerators and freezers, and as a propellant in aerosol sprays. When used as a refrigerant or a propellant, isobutane is also known as R-600a.
