Sigma Refrigeration

Backed by our vast industrial acquaintance of this realm, we are involved in presenting of Plate Type Condenser. We provide this product at reasonable prices.

Creating optimum conditions in the coldstore to preserve the fruit longer so that the consumer can enjoy fresh fruit with a great taste all year round.

In simple terms a ULO storage is a gastight coldstore constructed from high quality insulated panels.Lowering the oxygen level and raising the CO2 value is called controlled atmosphere storage. Storage at an extremely low oxygen level is called ULO storage. During storage fruit 'breathes' using oxygen & producing ethyleen or carbon dioxide.The situation in the ULO cell depends on the type and variety of fruit and can be as follows:
refrigeration with temperatures ranging from -2ºC to 5ºC

Physical dangers and safety measures for ULO cells
Dangers:
Danger of suffocation
Danger of falling from the top of the ULO cell through the inspection hatch
Safety measures:
Clear warning sticker in several languages
Light signals
Barred openings behind gastight inspection hatches
Special locks on the gastight entrance doors

Do you have renovation or building plans for a ULO cell?

The basis for optimum condition in a ULO cell is the objective of 100% gastightness of the cell.Sigma Projects has developed the gastight building concept for this purpose.For applying this concept Sigma uses high quality insulated panels to build the coldstore.The precise fitting of the insulated panels & vapour-proof construction details guarantee a vapour-proof construction with optimally fitting joints.We give the coldstore a vapour-proof finish on the ‘warm’ outside.Careful sealing and gastight coating on the inside of the joints profiles ducts for pipes and finishes of the corners in walls and ceilings take care of the rest.
