Description
Refrix R‑407C Refrigerant Gas
Refrix R‑407C is a zeotropic HFC blend that delivers efficient cooling performance and is a popular long-term replacement for R‑22 in both residential and commercial HVAC systems. It closely mimics the thermodynamic properties of R‑22, making it ideal for retrofitting existing systems with minimal modification. With zero ozone depletion potential and good energy efficiency, R‑407C is used widely across air conditioning, heat pumps, and dehumidification systems.
Key Features:
-
✅ Zero Ozone Depletion Potential (ODP = 0)
-
✅ Similar pressure and performance to R‑22
-
✅ ASHRAE A1 Safety Classification (Non-flammable, Low toxicity)
-
✅ Suitable for new systems and R‑22 retrofits
-
✅ Good energy efficiency and cooling capacity
-
✅ Cost-effective long-term solution for HVAC equipment
Applications:
| Sector | Typical Uses |
|---|---|
| Residential AC | Split systems, ducted systems |
| Commercial HVAC | Rooftop units, packaged air conditioners |
| Industrial Cooling | Chillers, process cooling |
| Heat Pumps | Domestic and commercial heating/cooling |
| Dehumidifiers | Industrial moisture control units |
Usage Guidelines:
-
Must be used with POE (Polyolester) oil only
-
Charge the system as a liquid to maintain blend accuracy
-
Being a zeotropic blend, systems may require slight adjustments in expansion devices
-
Not compatible with mineral oil or alkylbenzene lubricants
-
Perform leak tests and ensure proper vacuuming during retrofits

FAQs
1. Is R‑407C a direct drop-in for R‑22 systems?
No, although it mimics R‑22 performance, retrofitting involves replacing the existing lubricant with POE oil and making adjustments to seals and expansion devices.
2. What are the main advantages of R‑407C?
R‑407C is non-ozone depleting, energy efficient, and offers similar pressures and capacities to R‑22, making it ideal for both new installations and retrofits.
3. Can R‑407C be topped up after a leak?
It is not recommended to top up R‑407C after a leak without fully reclaiming and recharging the system. As a zeotropic blend, its components may leak at different rates, affecting performance.
