The purpose of using compensating 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 compensating 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, up to 30 m³, up to 50 m³ and up to 120 m³.
