Description
Overview
SEASON Refrigerant Gas R-407C is a high-performance HFC refrigerant blend designed as an effective and environmentally safer replacement for HCFC R-22. With Zero Ozone Depletion Potential (ODP = 0) and excellent cooling characteristics, R-407C delivers strong thermodynamic performance, smooth compressor operation, and enhanced energy efficiency across residential, commercial, and industrial HVAC systems.
Widely used in split ACs, ducted systems, heat pumps, chillers, and commercial refrigeration equipment, SEASON R-407C is suitable for both new installations and R-22 retrofit applications.
Key Features
- Eco-Friendly: Zero ODP and chlorine-free formulation.
- R-22 Replacement: Designed for systems requiring similar pressure and temperature profiles.
- Stable Operation: Excellent thermodynamic stability and cooling consistency.
- Retrofit Compatible: Suitable for R-22 system conversions (with POE oil change).
- High Purity: ≥ 99.9% moisture-free filling.
- A1 Safety Rating: Non-flammable, low toxicity.
Applications
- Residential split & ducted air-conditioners
- Heat pumps and packaged HVAC units
- Commercial refrigeration systems
- Medium-temperature chillers
- R-22 equipment requiring an environmentally safer alternative

FAQs
1. Is R-407C a direct drop-in for R-22?
No. It requires proper retrofit steps including oil change and system flushing.
2. What oil is required for R-407C?
POE (Polyolester) oil only. Mineral oil is not compatible.
3. Can R-407C be mixed with R-22?
No. Mixing causes system damage and poor cooling performance.
4. What applications use R-407C?
Split ACs, ducted units, packaged systems, chillers, heat pumps, and commercial refrigeration.
5. Does R-407C have temperature glide?
Yes. Approximately 7–8°C — normal for zeotropic blends.
