What Is R32 Refrigerant for OEM?
R32 is the successor to the previous refrigerant R410A. This refrigerant is considered the one with the least negative environmental impact compared to its predecessors. Some manufacturers are already stopping production with R410A and switching to R32. Even so, R410A still exists in a number of maritime and legacy industrial applications.
In the HVAC manufacturing industry, R32 refrigerant has been widely evaluated and adopted by OEMs producing air conditioners and heat pump systems for international markets. Its application is based on real-world manufacturing experience, regulatory compliance, and performance testing conducted by HVAC engineers and production specialists.
A number of OEMs must focus on meeting R32 production quotas. This will help them prove to the public that this refrigerant in a heat pump is able to reduce carbon emissions. Manufacturers are active in producing R32 considering that its Ozone Depletion Potential (ODP) is zero. In terms of Global Warming Potential (GWP), R32 refrigerant is only 675, which is significantly lower than the GWP of R410A at 2,088. This difference directly affects system efficiency and the overall environmental footprint of the installed product, and also helps reduce operating and maintenance costs over the product lifecycle. For a deeper look at how R32 specifically reduces GWP in heat pump applications, you can read our article on R32 heat pumps and GWP reduction.
The adoption of R32 refrigerant aligns with global environmental regulations and international HVAC standards, including ISO 817 and regional safety classifications such as A2L. These standards are commonly referenced by manufacturers, compliance teams, and regulatory bodies to ensure safe and efficient refrigerant usage across residential and commercial systems.
R32 refrigerant is a single-component refrigerant, which means it can be easily recycled after use. Factories can recover and reprocess it without the blend-separation issues that affect mixed refrigerants like R410A, making it a cleaner choice across the full product lifecycle.

What Is R32 Refrigerant Safety Standard?
Technicians know that R32 is a mildly flammable refrigerant. However, the potential for burning is quite low, so it is safe as complementary heat pump equipment for cooling systems in homes or offices. Technicians need to take appropriate safety measures when carrying out the transport, storage, and installation of this refrigerant.
They must understand what R32 refrigerant requires from its environment so that the gas does not come into contact with ignition sources that can start a fire. Technicians must also ensure R32 does not combust or emit toxic substances such as hydrogen fluoride and carbon dioxide.
There are several things technicians need to do to address safety issues when working with R32 refrigerants.
Pay Attention to Flammable Refrigerant Safety Guides
Manufacturers and suppliers should include additional safety information in the manual so that technicians who install or service air conditioning units with R32 refrigerant can carry out their work efficiently and safely. Clear documentation is the first line of defense against installation errors that could create flammability risks.
Safety and Health Institutions
Technicians should already possess information regarding material safety from Safety and Health institutions in the country where they work. This knowledge is crucial as it represents a specialized form of protection during the installation of R32. For instance, in Australia, the Australian Standard AS/NZS ISO 817:2016 categorizes R32 as A2L, indicating lower flammability.
Technicians must adopt specific safety measures for the proper transport, storage, and handling of this mildly flammable gas, ensuring that it remains shielded from open flames or other potential ignition sources. Combustion of R32, similar to all fluorinated refrigerants, generates toxic substances including hydrogen fluoride and carbon dioxide. This creates a risk of asphyxiation and freeze burns. It is strongly recommended that technicians use appropriate personal protective equipment (PPE) such as safety goggles, gloves, and a face mask.
Pay Attention to the Use of Dry Nitrogen
Technicians should understand the importance of using dry nitrogen when carrying out the brazing process. This substance can prevent oxidation on the inside of the pipe, thereby preventing concentration levels that could cause fire risk during installation.
Pay Attention to the Size of the Room
The technician can advise the property owner if more space is needed to install the indoor unit. This is particularly important when a gas leak occurs in the unit, as more space provides additional time before the leaked refrigerant reaches a concentration level at which it could ignite.
Installing a Split System AC
A split system air conditioning installation requires attention to refrigerant concentration levels in line with the duct system. Providing an adequate duct system ensures that the R32 refrigerant charge maintains its safety parameters during and after installation.
