The perfect conditions for preserving fruit

The aim is to regulate the concentration of oxygen (O2), carbon dioxide (CO2), and ethylene (C2H4) to keep the fruit in optimum condition. In maintaining this perfect atmosphere, it is important that the fruit cell is and remains gas-tight. This is where CA and ULO preservation technologies play a crucial role.

What is Controlled Atmosphere preservation?

In Controlled Atmosphere (CA) preservation, oxygen concentration is reduced and carbon dioxide concentration is increased to slow down the respiration of the fruit. This delays ripening and preserves fruit quality over a longer period of time. CA preservation is often used for apples, pears and other fruits.

Understanding ''Ultra Low Oxygen'' preservation?

Ultra Low Oxygen (ULO) preservation goes one step further by significantly lowering the oxygen concentration. This allows apples and pears to be stored even longer without loss of quality. This is especially beneficial for exporting fruit over long distances.

What kind of doors are suitable for fruit storage?

After fruit has been picked, the ripening process can therefore be delayed by storing the fruit in the special cold stores. To effectively implement CA and ULO technologies, our gas-tight doors are indispensable. Our doors ensure that the gas-tight cells remain accessible and can be sealed 100% gas-tight using an inflatable rubber and a bicycle pump.

Most cells are fitted with a sliding door, which can be designed to slide both horizontally and vertically. We also supply gas-tight hinged doors, inspection windows and hatches. The gas-tight refrigeration doors are made to measure and are available in large sizes, as a kit if required.

Discover all the benefits of gas-tight doors

Our gas-tight doors offer numerous advantages for the gas-tight storage of various fruits:

100% gas-tight thanks to the unique inflatable seal

You achieve optimum gas-tightness with our innovative inflatable seal. This system adapts to changes in pressure and temperature, keeping your fruit in optimum condition.

Durable and reliable

Our doors are designed to function trouble-free for years, even in situations where there are irregularities in floors and walls. You can count on long-term and consistent gas tightness for optimal fruit preservation.

Elimination of vaseline or sealant requirements

Thanks to our sealing system, you no longer need vaseline or sealant. You save time and minimise potential sources of contamination in your storage cells.

Efficient and smooth operation

Our doors are designed for fast and smooth operation, increasing efficiency in your fruit storage facility. In most cases, the doors are operated manually but the doors can also be automatic with electric operation.

Seamless door leaf and thermal bridge-free frames

Thanks to seamless door leaves and cold-bridge-free frames, our refrigeration doors effortlessly maintain the desired temperature and gas conditions.

Lightweight and customizable

Made of high-quality polyester, our doors are lightweight. They are also available in various colours, making your storage facility both functional and visually appealing.

Available as a kit

We can supply the doors as kits for flexible self-assembly, easy transport and favourable pricing.
