At the beginning of the 1980’s, the ULO/CA-storage of fruit commenced and the demand for gastight doors arose. For this, Salco developed a gastight refrigeration door with the unique, patented inflatable sealing system.

ULO stands for Ultra Low Oxygen and CA stands for Controlled Atmosphere. With this storage method, an atmosphere with low oxygen content (sometimes lower than 1%), an increased CO2 content, and a temperature and air humidity that depends on the product is created in a gastight refrigeration room. Through this, the ripening is slowed down, as a result of which the storage life is extended. Among other things, Controlled Atmosphere is applied to:

• Long-term storage of fruit

• Storage of vegetables (cabbage) and bulbs

• Controlling insects in cocoa, rice, tobacco, archives and conservation in museums

• Fire prevention

Our doors are in various designs also used for the sealing of biogas tunnels.  Storage and/or treatment takes place in gastight spaces.  The door constitutes a critical component in relation to this.

Prominent in CA doors world-wide

In 35 years, Salco has developed into a well-known name in various industries at home and abroad, in which the fruit industry is our most important export market. We work together with a network of distributors throughout the world. Specialised businesses that know the local market and dispose of an own organisation with sales, installation and service.

The why and wherefore of Salco CA doors

Salco's gastight doors are provided with a unique inflatable seal that guarantees 100% gastightness.  This seal consists of two parts an inflatable, continuous inner tube and a protective, flexible sealing rubber on the outside that presses against the floor and the door frame by pumping up the tube. In this manner, a first-rate seal is created that is unequalled all over the world.

Owing to its air pressure and flexibility, the sealing rubber follows any possible irregularities in the floor and the wall.  Even changes in the floor as a result of driving in and out are intercepted well.  Extra security and still 100% sealed after years of operation.

The seal is not created by squeezing the door shut by great force (as a result of which wear and leakage will soon develop), but by means of steady air pressure in the sealing system. In this manner, point concentrated loads are avoided and the gastightness is ensured for a long time. No vaseline or sealant is necessary for gastight sealing, not even after years of use. Because of this, the room can be opened and sealed gastight in seconds and everything stays clean.

For checking, the air pressure of the seal is readable on the integrated pressure gauge. The 4” thick door is lightweight owing to the use of high quality, seamless polyester, and available in several colours. The door frame and framing are completely free of thermal bridges and executed in anodized aluminum. The doors are available in a horizontal and a vertical design, and as a hinged door.
