Description
R-32 (Difluoromethane) is a next-generation single-component HFC refrigerant known for its superior energy efficiency and significantly lower Global Warming Potential (GWP) compared to traditional blends like R-410A. With increasing environmental regulations worldwide, R-32 has become the preferred refrigerant in modern air conditioning systems designed for sustainability and high performance.
Key Features and Benefits:
✅ Low GWP solution: R-32 has a GWP of only 675—approximately 70% lower than R-410A—making it a climate-conscious choice for eco-friendly HVAC systems.
✅ High energy efficiency: Offers excellent heat transfer and refrigeration capacity, leading to lower electricity consumption and improved system performance.
✅ Pure refrigerant: As a single-component refrigerant, R-32 is easier to recover and recycle, with no glide issues compared to multi-blend refrigerants.
✅ Next-gen compatible: Supported by many new high-efficiency air conditioning and heat pump systems; ideal for forward-looking installations and retrofits (where applicable).

Frequently Asked Questions
Everything contractors and facility managers ask before placing a refrigerant order.
Compatibility depends entirely on your equipment. Always verify the system nameplate, manufacturer service manual, and EPA guidelines before charging. R-32 is only for systems specifically designed for it. Using the wrong refrigerant can damage compressors and void warranties.
Under Section 608 of the Clean Air Act, refrigerants sold for appliance servicing can only be purchased by certified technicians. By checking out, you confirm you hold valid EPA Section 608 Type I, II, III, or Universal certification. We reserve the right to request credential verification before shipment.
No. Refrigerants should never be mixed unless the equipment manufacturer explicitly permits it. Mixing refrigerants creates unpredictable pressures, reduces efficiency, contaminates recovery equipment, and violates EPA regulations. If a system has been contaminated, it must be fully recovered, flushed (if applicable), evacuated, and recharged with virgin refrigerant.
Store upright in a cool, dry, well-ventilated area away from direct sunlight, open flames, and heat sources above 52°C (125°F). Keep the protective cap on the valve when not in use.
When stored correctly, sealed refrigerant cylinders have an indefinite shelf life. Once opened, use the contents promptly and reseal the valve tightly after each service call.
Most orders ship within 1 business day and arrive in 4–9 business days via ground transport. Cylinders are classified as hazardous materials (ORM-D / limited quantity) and are packed in compliance with DOT regulations, with protective caps and secure outer packaging to ensure safe delivery.
Contact us within 48 hours of delivery with photos of the packaging and product. We will arrange a replacement or full refund at no cost to you. Due to safety regulations, we cannot accept returns on opened or used refrigerant cylinders.
