Why is this gas usually cheaper per kg than R410A? The EU HFC phase-down caps the quantity of HFCs placed on the market in tonnes of CO₂ equivalent. With a GWP of 675, roughly a third of R410A's, each kilogram uses far less quota. The cap still tightens over time for all HFCs, so prices can move.

R32 technical data
R32 is difluoromethane (CH₂F₂), a pure, single-component HFC rather than a blend. It has no temperature glide: at a given pressure it boils and condenses at one temperature, and a leak does not change the composition of what remains in the circuit.
| Chemical name | Difluoromethane, CH₂F₂ |
|---|---|
| Family | HFC (hydrofluorocarbon), pure single-component fluid |
| Safety class (ISO 817 / ASHRAE 34) | A2L — lower toxicity, mildly flammable |
| Global warming potential (GWP, AR4) | 675 |
| Ozone depletion potential (ODP) | 0 |
| Boiling point (1.013 bar) | approx. −51.7 °C |
| Temperature glide | none (pure fluid) |
| Critical temperature | approx. 78.1 °C |
| Critical pressure | approx. 57.8 bar |
| Compatible oil | POE (polyolester) |
| Transport | UN 3252, ADR class 2.1 (flammable gas) |
| CO₂ equivalent of a 9 kg cylinder | 6.1 t CO₂ eq |
Operating pressures are close to, and slightly above, those of R410A, while compressor discharge temperatures run higher, which is why equipment is designed specifically for this fluid. Saturation pressures for each temperature are listed in the pressure-temperature chart further down this page.
The 6.1 t CO₂ eq figure for a 9 kg cylinder (9 kg × GWP 675) is the one to use when expressing a system charge in tonnes of CO₂ equivalent, the unit behind the F-gas obligations.
What is R32 used for?
R32 is now the standard in most new split air conditioners and in many heat pumps sold across Europe. Compared with R410A it offers better energy efficiency and needs a smaller charge for the same capacity. You will find it in:
- residential and light-commercial split and multi-split air conditioners;
- air-to-water heat pumps, including monobloc units replacing oil or gas boilers;
- air-to-air heat pumps and small commercial systems designed for it.
Our cylinders cover commissioning, additional charge for long pipe runs, servicing and recharging after a leak repair. Only use it in equipment designed for it: the nameplate always decides.
Handling an A2L refrigerant safely
A2L means mildly flammable: hard to ignite, with a slow flame speed, but able to burn at certain concentrations in air when an ignition source is present. Equipment manufacturers allow for this with charge limits and installation rules; on site, a few precautions apply:
- A2L-rated tools: recovery unit, vacuum pump and leak detector suitable for mildly flammable refrigerants.
- Ventilation of the work area, especially in small rooms, basements and plant rooms.
- No ignition sources: no naked flames, sparks or smoking near the circuit; recover the refrigerant and purge with nitrogen before brazing.
- Follow the manufacturer's charge limits relative to room size.
Cylinders travel as a flammable gas, UN 3252, ADR class 2.1: upright and secured in the van, valve cap fitted, in a ventilated load space and out of direct sun.
Who can buy R32? EU F-gas rules
Despite its lower GWP, R32 is still a fluorinated greenhouse gas. In every EU Member State it falls under the F-gas Regulation (EU) 2024/573, which replaced Regulation (EU) No 517/2014, together with national implementing rules.
- F-gas certificate per Member State: technicians and, depending on the country, companies are certified under each Member State's national scheme; certificates issued in one EU country are recognised in the others.
- Leak checks: required from 5 t CO₂ eq, which means from about 7.4 kg of this refrigerant in a circuit, at the frequency set by the Regulation. Many domestic splits stay below that threshold.
- Record keeping: operators keep records for equipment subject to leak checks, and suppliers keep records of sales.
- New equipment: restrictions on placing certain new equipment on the market are phased in by product type and GWP; check the current text before specifying a new installation.
Venting is prohibited: refrigerant must be recovered before a circuit is opened and sent to an approved recycling, reclamation or destruction channel. Local paperwork varies by country, so check your national authority's requirements.
How to charge an R32 system
Because it is a pure fluid, it can be charged as vapour or as liquid without affecting its composition, unlike blends.
- Vapour suits small, slow top-ups; liquid suits larger charges, throttled on the low-pressure side to protect the compressor.
- Weigh the charge with a refrigerant scale: nameplate quantity plus any additional charge per metre of pipework.
- Pull a deep vacuum and confirm it with a micron gauge: POE oil is highly hygroscopic.
- Use a manifold and hoses rated for the pressures involved and suitable for A2L.
- Check superheat and subcooling against the pressure-temperature chart (bar gauge and absolute, in °C).
Topping up after a small leak is technically possible with a pure fluid, but good practice is still to find and fix the leak first.
R32 vs R410A vs R454B: which do you need?
R32 is not a drop-in replacement for R410A. A system built for R410A must be recharged with R410A, and an R32 unit only with R32.
| Refrigerant | GWP | Safety class | Main use |
|---|---|---|---|
| R32 | 675 | A2L | New split air conditioners and heat pumps |
| R410A | 2,088 | A1 | Servicing the installed base |
| R454B | 466 | A2L | Some new equipment designed for this blend |
R410A is itself half difluoromethane, but its R125 content makes it non-flammable and changes its behaviour. Switching refrigerant on existing equipment is only acceptable where the manufacturer explicitly approves it.

Frequently asked questions about R32
Is R32 flammable?
Mildly. It is classified A2L: difficult to ignite, with a low flame speed. Work with A2L-rated tools, ventilate the area, keep ignition sources away and only use it in equipment designed for it.
Can R32 replace R410A in an existing system?
No. It is not a drop-in replacement: pressures, discharge temperatures and safety requirements differ. An R410A system must be recharged with R410A unless the manufacturer approves otherwise in writing.
How much does R32 cost per kg?
It depends on the cylinder size. The price table at the top of this page shows the final price incl. VAT and the price per kg for 5, 9 and 30 kg cylinders. The refillable cylinder is included with no deposit, and delivery is free.
Who can buy R32 in the EU?
Under Regulation (EU) 2024/573, only businesses holding the relevant F-gas certificate issued in an EU Member State, or distributors. You can order straight away: we ask for a copy of your certificate after the order, before dispatch.
Which oil does an R32 system use?
Polyolester (POE) oil, of the grade specified by the compressor manufacturer. POE is highly hygroscopic, so keep containers sealed and pull a deep vacuum before charging.
Should R32 be charged as liquid or vapour?
Either. As a pure fluid with no glide, its composition does not change. Vapour suits small top-ups; liquid suits larger charges, throttled on the low-pressure side. Always charge by weight.
What is the difference between R32, R410A and R454B?
R32 is a pure A2L HFC with a GWP of 675, used in most new splits. R410A is an A1 blend with a GWP of 2,088 for servicing existing systems. R454B is an A2L blend with a GWP of 466 used in some new equipment. They are not interchangeable.
Where can I find an R32 pressure-temperature chart?
On this page, just above the FAQ: it lists saturation pressures in bar, gauge and absolute, at each temperature in °C.
How do I pay, and how fast is delivery?
By bank transfer: you receive our SEPA details and reference as soon as you order. Once the funds arrive and your certificate is checked, the cylinder ships free within 3–5 working days by an ADR carrier, with tracking.
What do I do with the empty R32 cylinder?
It is included in the price and becomes yours, with no deposit. Keep it for refilling or hand it to an approved take-back channel. Never vent residual gas or put the cylinder in general waste.
Does an R32 system need leak checks?
Periodic leak checks apply from 5 tonnes of CO2 equivalent, which is about 7.4 kg of R32 in a circuit. Many domestic split systems stay below that threshold.
Also working with R410A?
R410A has replaced R32 in most new air conditioners and heat pumps. We supply it too, in refillable cylinders and on the same terms: payment by bank transfer, dispatch within 3–5 working days. The two refrigerants are not interchangeable: a R32 system is only recharged with R32, a R410A unit only with R410A.
