Controlled-Atmosphere Rooms
CA rooms that slow ripening and extend shelf life for apples, avocados, berries, and more — with precise O₂, CO₂, temperature, and humidity control.
- ✓ Gas-tight panel envelope
- ✓ O₂ / CO₂ / N₂ control
- ✓ Precision sensors
- ✓ Shelf life in months
Engineered for your application
CA rooms that slow ripening and extend shelf life for apples, avocados, berries, and more — with precise O₂, CO₂, temperature, and humidity control.
Gas-tight construction
Aluminum-faced panels with sealed joints and specialized door systems keep O₂ and CO₂ levels exactly where your crop needs them.
Precision atmosphere control
N₂ generators, CO₂ scrubbers, and oxygen control systems hold target atmospheres within tight tolerances, 24/7.
Crop-specific programming
Storage regimes tuned per crop — from high-CO₂ berry storage to low-oxygen apple rooms — with full data logging.
Long-term storage economics
Sell into better market windows: CA storage can extend fresh fruit life by 4–9 months versus conventional cold storage.

Frequently Asked Questions
Which products benefit from CA storage? +
Apples, pears, avocados, kiwifruit, berries, stone fruit, and many vegetables keep for months in the right atmosphere, versus weeks in conventional cold rooms.
How tight is the gas control? +
We hold O₂ within ±0.2% and CO₂ within ±0.3% of setpoint using redundant sensors and automated N₂/scrubber control.
Can an existing cold room be converted to CA? +
Often yes — the room needs a gas-tight envelope, sealed door, and atmosphere equipment. We can assess your existing room and quote the conversion.
