CO2 (R744) is a natural refrigerant with a GWP of just 1. It's fast becoming the refrigerant of choice for supermarkets and industrial plant, with real environmental benefits and efficient operation.

CO2 systems run at much higher pressures than traditional plant, so they need engineers who know them. We commission, service and repair both transcritical and DX CO2 systems.

What we do

Transcritical CO2 plant commissioning: testing, charging and programming
DX CO2 plant servicing, including oil changes and system flushing
Controller set-up and programming (for example RDM)
Front-end and monitoring set-up
Breakdown repair and planned maintenance

Records and compliance

CO2 isn't a fluorinated gas, so F-Gas leak-check rules don't apply to it, but high-pressure systems still need careful maintenance and records.

How it works

Call or message. Ring 07932 647581 any time, or request a quote.
We diagnose and quote. You get a clear explanation and price before any major work.
Done, with a written record. We test everything and leave you the paperwork.

Questions about CO2 refrigeration

Why CO2?

It's a natural refrigerant with a GWP of 1. That means it's not affected by the F-Gas phase-down and bans hitting high-GWP gases like R404A.

Do you work on transcritical systems?

Yes. We've commissioned transcritical CO2 plant: tested, charged, programmed and running on RDM controls, with the site set up on the front end.

Can you service a CO2 system someone else installed?

Yes. For example, we've serviced DX CO2 plant with an oil change and system flush.

Is CO2 suitable for my business?

It depends on the size and type of your system. We'll give you an honest view of CO2 against the other low-GWP options.
