Compatible applications
R-22 retrofits
Approved conversions where the manufacturer publishes a procedure.
Air conditioning
Comfort cooling equipment originally designed for R-407C.
Medium-temp refrigeration
Coolers and process systems in the medium-temperature band.
Before you order
R-407C has roughly 13 °F of temperature glide. Take superheat and subcooling from a pressure-temperature chart that lists dew and bubble points separately, or your readings will be wrong.
Retrofitting from R-22 requires an oil change to POE. Mineral oil will not circulate reliably with this blend.
Safe handling
- Verify the equipment nameplate specifies R-407C and note the approved charge before connecting.
- This system requires POE (polyol ester). Mixing incompatible lubricants causes compressor failure.
- Charge in the liquid phase only — vapour charging shifts the composition of a blend.
- Use gauges, hoses and recovery equipment rated for this refrigerant’s operating pressures.
- Store upright and secured, in a cool, dry, ventilated area away from heat, sparks and open flame.
- Recover refrigerant — knowingly venting is a violation of Clean Air Act Section 608.
Shipping
Service cylinder. High-glide zeotropic blend. Charge liquid only and use dew/bubble point P-T data. Follow the cylinder label, safety data sheet and equipment manufacturer instructions.
