HFC R32 Products

LG R32 A2L (MILDLY FLAMMABLE) refrigerant range of Splits, Multi & Commercial AC Equipment (Up to 12kW)


WHY R32? is it Flammable? is it Permanent? is it covered by HSE?


GWP 2088


High Global Warming Potential  IF LEAKED BUT Non-FLAMMABLE



Current refrigerant for all systems (Splits, Multi Split and VRF ) since 2004. All in accordance with current F-Gas regulations and Health & Safety regulations (HSE). No bans (except split systems with a total charge of less than 3kg by 2025 with 4year extension if there are technical or safety issues ) or end of the line for any equipment containing more than 3kg charge or availability for service.


GWP 675 


Low Global Warming Potential IF LEAKED BUT FLAMMABLE


R32 refrigerants require special risk assessment as it is considered by HSE (Health & Safety Executive) as highly flammableIt falls under DSEAR (Dangerous Substances and Explosive Atmospheres Regulation) UK Regulations. or Europe ATEX. BSEN 60079-10-1:2015


Important:  F-Gas Regulations CANNOT cover any competence on SAFETY as it is primarily an Environmental qualification ensuring environmentally safe handling, NOT PERSONAL SAFETY.

For installer Personal Safety you need:  City & Guilds 6187-21 or equal and approved.


Installers carry the ultimate responsibility and must
inform end-users of the Flammability Risks.

See advisory documents by 

R32 can only be used in small applications (Max 12kW or less than 3kg charge per systems - outdoor, indoor and pipe works), (see F-Gas equipment sale ban by 2025 - NOT use)  See F-gas Bans and LG Recommendations

It is the responsibility of the installer to ensure equipment have clear labeling and warning and are transparent to end-users, and emergency services. Building owners must ensure that their insurance providers are aware of the risks associated with flammable refrigerants.

This course covers all Hydrocarbon refrigerants, including handling of A3 hydrocarbons including R1270 Propylene, R290 Propane and R600a Isobutane. It is also suitable for engineers working with flammable HFO’s and HFC’s including R1234yf, R1234ze and R32

Protocols & Progress

- R32 is an HFC refrigerant Class A2L  (A2L not Used in Large (greater than 3 kg system charge) Splits, Multi splits, VRF or Chiller systems ). It is not a long-term refrigerant, cannot be dropped in, requires Specific Risk Assesment unders DSEAR, require extra training (installer safety) to handle flammables e.g. City & Guilds 6187-21 and require specific guidelines (see LG installation recommendations).

R410A or R134a or R407C  are HFC refrigerants (common Air Conditioning refrigerants which are A1classified (non Flammable), used in Splits, Multi, Commercial, VRF, Chillers, Roof Tops ) - (See F-Gas 2014 Regulations Specifically point 3 (new HFC ban)

the final solution? :

There two regulations that affect the reduction of current HFC refrigerants with high GWP.

The  European F-Gas and the Kigali Amendments to Montreal Protocole.

None of them is legally binding and there is no phase-out, and both rely on the future innovation of new Lo GWP refrigerants and equipment manufacturers ensuring no waste and better control on leakage (40 % of refrigerants used in AC/ Refrigeration is used in servicing). see links to both.
