MINUS50-9KG HyChill Minus 50 Hydrocarbon Refrigerant 9kg, Replacement for R22, R404A and R502 Systems, Licensed Technicians Only

MINUS50-9KG is HyChill Minus 50 refrigerant in a 9kg size, the larger pack for workshop and trade use. Minus 50 is offered as the replacement for R22, R404A, R502 and other similar f-gases, which covers plenty of commercial refrigeration and older air conditioning plant. It's intended for licensed refrigeration technicians working on equipment that suits a hydrocarbon charge.

Where HyChill Minus 50 fits in

R22 and R502 are ozone depleting gases that have been phased out of new equipment, and R404A carries a very high global warming impact, so many technicians look for an alternative when a system needs regassing or conversion. HyChill Minus 50 is a hydrocarbon refrigerant offered for that job. Hydrocarbons are flammable, which changes how a system must be assessed, charged, labelled and serviced. Charge weights are usually far lower than for the gas being replaced, so follow HyChill's charging data rather than the original nameplate. Fix any leaks and evacuate the system properly before charging.

Handling and charging safely

Only a licensed refrigeration technician should charge a system with Minus 50, following the rules in their state for flammable refrigerants. Isolate power to the equipment before opening it up, ventilate the work area and keep ignition sources well away. Use gauges, recovery gear and leak detectors rated for hydrocarbons. Store the cylinder upright in a cool spot, out of direct sun.

Questions about this part

Can I put Minus 50 straight into an R22 or R404A system?

Not without an assessment. The system must be checked as suitable for a flammable hydrocarbon refrigerant, the old gas recovered, leaks repaired and the system evacuated, then charged to HyChill's figures and relabelled. This is work for a licensed refrigeration technician.
