Controlled‑atmosphere (CA) cold storage builds upon standard refrigerated cold rooms by adding air‑tight enclosure and gas‑regulation systems. It precisely controls temperature, humidity, oxygen (O₂), carbon dioxide (CO₂) and ethylene levels to place fresh produce into a near‑dormant state. It is a proven high‑end storage solution for long‑term fruit and vegetable preservation.
One recent client planned a CA cold storage facility for local fruits and vegetables, targeting off‑season sales to boost product profit margins.
Project parameters:
- Floor area: 2500 m²
- Total volume: 16250 m³
- Internal height: 6.5 m
- Layout: 6 separate chambers, around 400 m² per chamber
Compared with ordinary fresh cold rooms, CA cold storage requires additional gas‑control equipment and special air‑tight CA‑rated doors, leading to higher overall investment.
This project features high ceiling and multiple independent chambers, equipped with Bitzer refrigeration compressors and 100 mm double‑sided color‑steel polyurethane insulation panels. These specifications raise total project cost by approximately 1%‑3% versus basic CA cold‑storage configurations.
Preliminary budget reference:
Complete CA controlled‑atmosphere cold storage: $620,000 ‑ $690,000 USD
Comparable standard fresh cold room (without CA gas system): $345,000 ‑ $485,000 USD
All figures are for preliminary budget reference only, not formal commercial quotation. Final price varies with local tax, freight, site condition and project scope.

FAQ
Q1: What main extra equipment does a CA cold storage need compared with a regular fruit cold room?
A: CA cold storage adds gas‑tight structural treatment, special CA airtight doors, gas generators, CO₂ scrubbers, ethylene removal units and real‑time gas composition monitoring sensors.
Q2: Why do multiple separate chambers increase CA cold‑storage project cost?
A: Each independent chamber needs separate air‑tight sealing, individual gas‑control hardware and dedicated doors. More chambers mean higher material and engineering workload.
Q3: What information should I prepare for CA cold‑storage quotation?
A: Please share floor area or total volume, planned chamber quantity, target stored fruits & vegetables, expected storage duration, site drawings and photographs of your land.
