•The purpose of using decompression valves at cold rooms is to maintain the internal and external pressure balanced. The pressure variations periodically occur during the different defrosting phases and during the opening & closing of the cold room door.
•The lack of a decompression valve installation may cause the following problems: quick door opening resulting in deterioration of the stored products and crackings in coincidence of the panel connections and consequent frosting.
•The valves are supplied in three different models depending of the internal volume (V) of the cold room – small (from 30 up to 50 m³), medium (from 50 up to 100 m³) and large (from 100 and up to 800 m³).
