Description
Overview
KALTON Refrigerant Gas R-407C is a high-efficiency HFC refrigerant blend designed as a reliable and eco-friendly replacement for HCFC R-22. With a composition of R-32, R-125, and R-134a, R-407C delivers pressure-temperature characteristics similar to R-22, making it the preferred choice for retrofit and upgrade projects. It offers Zero Ozone Depletion Potential (ODP = 0), stable cooling performance, and low toxicity, making it suitable for residential, commercial, and industrial HVAC environments.
Its strong thermodynamic behavior and energy-efficient operation ensure long-term reliability for split ACs, heat pumps, rooftop units, and medium-temperature refrigeration systems.
Key Features
- Zero ODP: Environmentally safer alternative to R-22.
- R-22 Performance Match: Similar pressure-temperature characteristics facilitate retrofitting.
- Strong Cooling Efficiency: Stable system performance across varied conditions.
- Economical Retrofit: Ideal for converting older R-22 systems.
- A1 Safety Class: Non-flammable, low-toxicity refrigerant.
- High Purity: ≥ 99.9% moisture-free formula.
Applications
- Residential split & window AC retrofits
- Commercial ducted units & rooftop HVAC systems
- Heat pumps
- Medium-temperature refrigeration systems
- R-22 replacement in compatible HVAC equipment

FAQs
1. Is R-407C a direct drop-in replacement for R-22?
No. It requires proper retrofit steps including oil change, line flushing, and liquid charging.
2. What is temperature glide?
A phase-change temperature difference (~7–8°C) that affects evaporator design and superheat settings.
3. Can R-407C be used instead of R-410A?
No. R-407C operates at different pressures and is better suited for R-22 retrofits.
4. What oil is compatible with R-407C?
POE (Polyolester) oil only.
5. Is R-407C safe?
Yes—classified A1, non-flammable and low toxicity.
