1811227 R600a Refrigerant Gas 420g Can, Isobutane Refrigerant for Servicing Domestic Fridges and Freezers

R600a, also known as isobutane, is the refrigerant used in many modern domestic fridges and freezers. Part 1811227 is a 420g can of R600a for technicians recharging sealed systems that were built for it. Only use it where the compressor label or rating plate specifies R600a, and never mix it with other refrigerants. It is classed as dangerous goods, which can affect how it is shipped.

Using R600a refrigerant safely

R600a is a hydrocarbon refrigerant, and it is highly flammable. That is why it is supplied for trained refrigeration technicians rather than for home repairs. A fridge that runs but won't cool, with a warm evaporator and a compressor that never stops, may have lost its charge through a leak. The leak has to be found and repaired and the system evacuated before it is recharged to the weight shown on the rating plate. Work in a well ventilated area, well away from any ignition source.

• 420g can
• Classed as dangerous goods
• For fridges and freezers designed to run on R600a

Who should use this refrigerant

Sealed system work should only be done by a qualified, appropriately licensed refrigeration technician with equipment rated for flammable refrigerants. Unplug the appliance first, and check the refrigerant type and charge weight on the rating plate. Ventilate the work area, keep sparks and flames away, and leak test the system after recharging. Store the can in a cool place out of direct sun.

Questions about this part

Can I regas my own fridge with this?

Not safely. R600a is highly flammable, and recharging needs leak repair, evacuation and an accurate charge by weight. Have the work done by a qualified refrigeration technician who works with hydrocarbon refrigerants.
