Which manufacturers supply CO₂ (R744) systems?

29 companies in the ColdMatch directory publish CO₂ (R744) refrigeration systems, with the largest concentrations in United States, Germany, Italy, Denmark. Each listing links to the manufacturer's own website so you can verify scope directly.

Is CO₂ (R744) the right refrigerant for my project?

That depends on capacity, temperature, site safety constraints, local regulation and the lifecycle energy cost, not on the refrigerant alone. A structured RFQ that states the duty and constraints — rather than naming a technology up front — usually returns comparable quotes across two or three refrigerant options.

How is the refrigerant facet determined?

It is derived from each manufacturer's own published product and technology information. Where a company publishes nothing about refrigerants, its listing is marked “not published” rather than assigned a value.

Does a listing mean the supplier is recommended by ColdMatch?

No. The directory is research content compiled from manufacturers' own published information. ColdMatch Group is not an automatic marketplace: every project brief is reviewed by our team before any supplier is approached, and suppliers are only introduced once the requirement is understood.

CO₂ (R744) refrigeration system suppliers

CO₂ (R744) systems — transcritical booster racks and NH₃/CO₂ cascades — are the mainstream low-GWP choice for new distribution centres and freezing facilities, particularly under F-Gas phase-down. 29 manufacturers in the ColdMatch directory publish work with this refrigerant, across United States, Germany, Italy, Denmark, Canada, Netherlands and other markets. A refrigerant facet is only shown when the manufacturer states it publicly — nothing here is guessed.

29 listings across 5 regions. Listing is research content, not a recommendation, certification or warranty of any company's performance.

How matching works

ColdMatch helps buyers prepare cold chain RFQs and source suitable suppliers.

Directory pages are for discovery and SEO. ColdMatch is not an automatic marketplace and does not directly connect buyers with refrigeration manufacturers — supplier matching and introductions are managed manually by ColdMatch.

Supplier and manufacturer listings are provided for research, transparency and discovery only. ColdMatch Group does not provide automatic buyer-supplier introductions. Every cold chain project request is reviewed manually by David / ColdMatch Group, and supplier introductions are made only after internal approval.

Refrigerant facets reflect what each manufacturer publishes about its own systems; suppliers with nothing published are shown as “not published” rather than guessed. Equipment lines are derived from each manufacturer’s own published scope, capacity bands and project-size facets are indicative of the project scale that supplier type typically serves, and none of it is a commitment. ColdMatch Group reviews every project brief before any supplier is approached.
