How much longer does CA keep produce than conventional cold storage?

CA can extend storage life for suitable long-hold produce, but the gain depends on cultivar, maturity at harvest and the protocol used. Agree target storage life and gas settings with a postharvest specialist and state them in the RFQ.

What does a CA room cost?

Cost depends on room count and size, envelope and door specification, gas equipment, controls and site works. ColdMatch does not publish a CA price list; use the cold storage cost tools for a framed budget and submit an RFQ so suppliers price the same scope.

Can an existing cold room be converted to CA?

Sometimes. The envelope, doors and floor must be sealed and pass an agreed pressure or leak test. Ask suppliers to survey the room and state the test method and acceptance value in their proposal.

Is ripening the same as CA storage?

No. Ripening rooms add and control ethylene to trigger ripening; CA rooms hold produce in a low-oxygen atmosphere to slow it. Specify them as separate duties.

Controlled Atmosphere

Controlled atmosphere (CA) storage for produce: rooms, gas control and buyer scope

Controlled atmosphere (CA) storage lowers oxygen and controls carbon dioxide in a gas-tight cold room so long-hold produce such as apples, pears and kiwifruit keeps longer than in conventional cold storage. The achievable storage life and gas settings depend on cultivar, maturity and the postharvest protocol, so they are set with a postharvest specialist, not taken from a supplier brochure. ColdMatch reviews CA projects of USD 250,000 and above, contacts suitable suppliers of gas-tight rooms, nitrogen generators, CO₂ scrubbers and controls on your behalf, and presents organized responses.

How matching works

You submit one RFQ. Our team handles the supplier outreach.

There is no direct buyer-to-supplier connection. Your request comes to the ColdMatch team, which contacts suitable suppliers and manufacturers on your behalf. Supplier and manufacturer information on this site is for research only; it is not a contact directory and does not mean a supplier has been vetted.

You build your project and submit an RFQ.
The ColdMatch team validates and organizes the requirements.
We contact suitable suppliers and manufacturers for you.
We present their organized responses to you through ColdMatch.

Supplier and manufacturer information is provided for research only; it is not a directory for direct contact.
