Controlled Atmosphere storage requires more than just low temperatures.

It demands a sealed environment where oxygen levels, humidity, and gas concentrations are carefully regulated to preserve the freshness of perishable goods.

Polarspec CA Doors are engineered specifically for these environments—where small refrigeration cells must be accessed frequently without compromising the sealed integrity of the room.

Our inflatable gasket design ensures a 100% gas-tight closure, even when walls and floors aren’t perfectly aligned. Whether you’re storing berries, bananas, or potatoes, Polarspec CA doors preserve product quality with every open and close.
