REFRIGERANT GAS MAXREF R‑410A

Mexref R-410A has established itself as the industry benchmark refrigerant for new air-conditioning and heat pump systems worldwide. Since its introduction as a replacement for ozone-depleting R-22, R-410A has been widely adopted by manufacturers for use in residential split systems, commercial rooftop units, ducted AC, and advanced VRF/VRV HVAC systems.

As a near-azeotropic blend of R-32 and R-125 (50/50), Mexref R-410A provides exceptional cooling capacity, high Seasonal Energy Efficiency Ratio (SEER) ratings, and stable operating characteristics with no temperature glide issues. It is completely ozone-safe (ODP = 0), though it carries a relatively high Global Warming Potential (GWP ~2088), which is why it is being phased down in some regions in favor of lower-GWP alternatives.

Despite ongoing regulatory changes, Mexref R-410A continues to be the most widely used refrigerant in HVAC today, thanks to its proven performance, reliability, and broad OEM acceptance.

Key Features:

• High Cooling Capacity – Delivers greater system output compared to R-22 and many other refrigerants.

• Excellent Energy Efficiency – Supports high SEER and EER ratings, reducing long-term operating costs.

• Environmentally Safer Alternative to R-22 – Zero Ozone Depletion Potential (ODP = 0).

• Stable Azeotropic Blend – No temperature glide, ensuring consistent performance and easy servicing.

• OEM Global Standard – Recognized and adopted by leading HVAC manufacturers around the world.

• Compatible with Modern System Designs – Suitable for advanced VRF, VRV, ducted, and split unit applications.

Applications:

• Residential Split Systems – Wall-mounted, ducted, and multi-split AC units.

• Commercial Rooftop & Packaged Systems – Widely used in large-scale cooling.

• VRF / VRV Systems – Advanced modular HVAC applications requiring efficiency and flexibility.

• Chillers & Heat Pumps – Systems designed for high-efficiency cooling and heating cycles.

Usage:

• System Compatibility – Only use with equipment designed for R-410A; not suitable for retrofitting older R-22 units.

• High-Pressure Handling – Requires POE lubricant and service tools rated for R-410A’s higher operating pressures.

• Installation & Maintenance – Must be installed, charged, and serviced by trained technicians following OEM and SAE/ASHRAE standards.

• Leak Management – Ensure proper leak detection and recovery due to the refrigerant’s high GWP.

Benefits at a Glance:

• Global industry standard refrigerant for HVAC

• High efficiency = reduced energy consumption

• Zero ozone depletion, environmentally safer than legacy HCFCs

• Strong OEM and aftermarket availability

• Reliable performance with stable blend properties

FAQs:

Can R-410A replace R-22?
No. R-410A operates at significantly higher pressures and requires different compressors, lubricants, and system components. Direct retrofit is not possible.

Is R-410A being phased down?
Yes. Due to its high GWP (~2088), many regions (EU, US, Japan, etc.) are gradually replacing R-410A with lower-GWP refrigerants such as R-32, R-452B, and R-454B. However, it remains dominant in the market today.

Is R-410A safe for residential use?
Yes. R-410A is non-toxic, non-flammable (ASHRAE A1 classification), and has been the standard refrigerant for modern HVAC systems for over two decades. Safe installation and servicing are essential.

What oil is required for R-410A systems?
All R-410A systems must use POE (Polyol Ester) oil, which provides proper lubrication under high-pressure conditions.
