How much longer does CA storage hold produce vs conventional cold?

Apples 8–12 months (vs 3–4 months conventional), pears 6–9 months, kiwi 4–6 months, cabbage 5–7 months. ULO (ultra-low O₂ ≤1%) adds another 15–25% shelf life for premium cultivars.

What CAPEX should we plan for a CA room?

Gas-tight CA rooms typically add USD 180–320 / m³ over conventional cold — plus USD 80–180K for N₂ generation, CO₂ scrubbing and ethylene control per room cluster. A 5,000 t apple CA facility usually lands USD 3–7M turnkey.

Can existing cold rooms be retrofitted to CA?

Yes if the envelope can be sealed to ≤1.5% leak/day — usually means new gas-tight doors, sealed panel joints, epoxy floor and a leak test. Retrofit CAPEX runs 40–60% of equivalent new CA build.

Do you handle ripening rooms as well?

Yes — we source ethylene ripening rooms for bananas, avocados, mangoes and stone fruit, including CO₂ scrubbing and pressurized-loading configurations.

Controlled Atmosphere

Controlled atmosphere (CA) & modified atmosphere storage for long-hold produce

CA and ULO rooms extend apple, pear, kiwi, avocado and onion shelf life from weeks to 8–12 months by holding O₂ at 1–3% and CO₂ at 1–5% under tight ±0.2°C control. ColdMatch sources gas-tight rooms, N₂ generators, CO₂ scrubbers, ethylene converters and ripening rooms for exporters, packhouses and cold storage operators. Commercial CA programs USD 250K–40M+.

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.

1. You submit a cold room, cold storage, industrial refrigeration, pharma cold chain, food logistics or mobile cold room request.
2. ColdMatch reviews your request and prepares the project brief — temperature range, product type, country, size, budget and operational needs.
3. Only after the brief is understood, ColdMatch searches for suitable suppliers.
4. David continues with you personally and introduces suppliers only when relevant.

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.
