MINUS30-4.5KG Genuine HyChill Minus 30 Refrigerant 4.5kg, R436 Type Replacement for R12 and R134a, Formerly HR12

HyChill Minus 30 is an R436 type refrigerant made as a replacement for R12 and R134a, and MINUS30-4.5KG is the 4.5kg size. Older paperwork and labels may still call it HR12, the name HyChill used before the change. It's supplied for licensed refrigeration and air conditioning technicians who service or convert systems that were built for those older gases.

Using Minus 30 in place of R12 or R134a

R12 has long been phased out and R134a is being phased down, so technicians working on older fridges and freezers need another option. Minus 30 fills that gap for systems that suit a hydrocarbon. R436 type blends are hydrocarbons, so this gas is flammable, and the system, the work area and the service gear all need to suit flammable refrigerants. The correct charge weight for a hydrocarbon differs from the R12 or R134a figure stamped on the rating plate, so charge by HyChill's guidance and not by the plate. Label the appliance clearly after converting it.

Safe handling

Handling refrigerant in Australia requires the right licence, and flammable refrigerants call for extra training and care. Store and use the cylinder upright, in a well ventilated spot away from flames, sparks and direct sun. Confirm the appliance and your recovery and charging equipment suit hydrocarbons before you start, and fit a flammable refrigerant label to any system you convert.

Questions about this part

Is Minus 30 the same as HR12?

Yes. HyChill sold this refrigerant as HR12 before renaming it Minus 30. If your records or an older system label mention HR12, Minus 30 is the current name for that same R436 type product.
