R407C Refrigerant Air Conditioning Cylinder 10kg

R407C is an established HFC refrigerant blend designed for air conditioning systems, heat pumps, and commercial refrigeration applications, offering dependable R22-comparable performance. Supplied in a rechargeable 10kg cylinder with a standard 1/4" connection, it delivers an effective and proven retrofit solution for existing R22 installations as well as new commercial setups.

Featuring zero ozone depletion potential and an A1 non-flammable safety classification, this ternary blend ensures broad system compatibility across split systems, VRF units, and residential or commercial heat pumps. Its reliable formulation provides efficient cooling capacity and stable operating characteristics when properly charged in the liquid phase.

Key Features

Highlights

• Zero ozone depletion potential (ODP = 0) with an A1 non-flammable safety rating
• Direct retrofit capability for R22 air conditioning and heat pump systems
• Supplied in a durable, rechargeable 10kg cylinder with a 1/4" valve connection
• Ternary HFC formulation (R32/R125/R134a) engineered for medium-temperature applications

Compatibility

Compatible with split systems, VRF systems, residential and commercial heat pumps, and cold rooms. Requires polyolester (POE) lubricant when retrofitting systems previously operated with R22 mineral oil.

How to use

R407C as a retrofit solution for R22 systems

R407C was specifically developed for the retrofitting of existing R22 systems. The performance data is similar to R22, which allows for a direct replacement in many systems. Typical procedure:

1. Recover R22 completely.
2. Replace mineral oil with polyolester (POE) in 2–3 cycles, as R407C is not compatible with mineral oil.
3. Replace the filter drier with an HFC/POE-compatible model.
4. Evacuate the system to remove moisture and foreign gases.
5. Charge R407C in liquid form according to the manufacturer's weight – do not mix with R22 residues.
6. Check for leaks as well as superheat/subcooling.

The temperature glide of ~5–7 K is a significant difference compared to pure refrigerants like R32. It influences the design of heat exchangers and expansion valves. Before any retrofit, the system must be professionally inspected. Only refrigerant that complies with the EN 378 and ISO 817 standards must be used.
