R407C refrigerant gas is a zeotropic HFC blend specifically engineered as a direct, high-performance replacement for R22 in existing air conditioning and refrigeration systems. Our premium R407C gas comes in a T-PED and EN 13322-1 certified refillable steel cylinder, providing the reliability and efficiency required for professional HVAC service.

Overview of R407C refrigerant gas

R407C is composed of a blend of R32, R125, and R134a, offering thermodynamic properties that closely match R22. It is the preferred choice for retrofitting older installations in commercial and residential split AC systems and heat pumps. Our cylinder options ensure you have the right volume for your maintenance tasks, from small top-ups to complete system overhauls.

Key technical features

• R22 Replacement: Optimized for retrofitting existing systems with minimal modification.
• Consistent Performance: Reliable thermal efficiency for both AC and heat pump applications.
• Certified Safety: Fully T-PED, CE, and EN 13322-1 certified for transport and storage.
• Refillable Design: Durable steel cylinders designed for controlled and eco-friendly refilling.

Technical Specifications

Professional R407C maintenance

When transitioning from R22 to R407C refrigerant gas, it is crucial to perform a complete system flush and ensure all seals and expansion valves are compatible. R407C is a zeotropic blend, meaning it should always be charged from the liquid phase to prevent fractionation of the components, which can affect system cooling performance.

Safety and handling guidelines

While R407C is non-flammable (Safety Class A1), standard safety precautions remain essential. Handle cylinders with care, store them upright in cool and dry areas, and always follow manufacturer guidelines for pressure limits and charging volumes. Proper training in F-GAS procedures is mandatory for handling all refrigerants professionally.

Frequently Asked Questions (FAQ)

Is R407C a direct drop-in replacement for R22?

R407C is a direct replacement, but it often requires checking oil compatibility (usually POE oil is needed) and possibly replacing expansion valves to match the operating pressures of R407C.

What makes R407C a zeotropic blend?

It means the different components (R32, R125, R134a) evaporate at different temperatures (temperature glide). Always charge from the liquid phase to maintain the blend consistency.

How is the R407C refrigerant packaged?

We provide professional-grade, refillable steel cylinders that are certified for European transport and storage standards.

Can I mix R407C with other gases?

No. Mixing refrigerants can drastically change pressure profiles and cooling efficiency, and it is strictly prohibited by safety regulations.
