R-407C Refrigerant for AC and Refrigeration Systems

R-407C Refrigerant for AC and refrigeration systems — a reliable R-22 replacement blend

R-407C from REAL GAZ is a zeotropic HFC blend of R-32, R-125 and R-134a (23/25/52 % by weight). Our R-407C Refrigerant for AC and refrigeration systems is widely used to retrofit and service equipment originally designed for R-22.
Each batch is blended gravimetrically and checked against AHRI 700 purity limits for moisture, acidity and non-condensables.

REAL GAZ supplies this refrigerant according to ISO 817, EN 378 and AHRI 700, suitable for commercial and industrial cooling duty.

🏭 Where R-407C Is Used

❄️ Comfort air conditioning — split, VRF and rooftop units with a temperature glide of roughly 5–7 K are charged in the liquid phase to keep the blend composition correct;
🏬 Supermarket cooling — medium-temperature display cases and chilled-food rooms use R-407C where an R-22 plant is being converted;
🏭 Process chillers — water chillers for plastics, printing and food plants rely on the stable capacity of this blend;
🚚 Transport and cold rooms — refrigerated vehicles and small cold stores are serviced with POE-lubricated R-407C systems.

⚙️ Trusted Gas Solutions

Because R-407C is a zeotropic blend, technicians must always charge from the liquid side and should recover and replace the charge after a vapour leak rather than topping it up. The refrigerant is classified A1 under ISO 817 — non-flammable and low toxicity — though its global warming potential is subject to EU F-gas phase-down rules, so records of purchase and use should be kept. Our team can advise on recovery cylinders, leak-check methods and compatible POE oils, and can confirm whether your plant is suitable for an R-407C conversion.

Typical R-407C charges are supplied in 11.3 kg, 13.6 kg and 25 kg class cylinders, and we can discuss other formats on request. When converting an R-22 system, remove the mineral oil as far as practicable, flush where the manufacturer advises, replace the filter-drier and check the expansion valve setting, because the glide changes superheat readings. Pressure–temperature charts for R-407C show separate bubble and dew values, so technicians should use sub-cooling at the liquid line to confirm charge. Finally, label the plant with the new refrigerant name, quantity and date of conversion.
