New PRV coming to the market from Fermod, but what are they?  
Pressure Relief Valves or PRV's are an integral component of any cold store unit. Cold room walls are subjected to the strains caused by variations in pressure, either from inside or outside. This can have an effect on the structure of the room and also make it difficult to open the door.  
 
So what does a PRV do? 
Ensures pressure equalisation  
Help the unit maintain a constant desired air temperature 
 
PRV's can be either wall or ceiling mounted. They should always be installed by a competent person.  
 
The video from Fermod demonstrates the benefits of PRV's and how to use them. Their full range of PRV's can be purchased from S.Tysoe Installations, call one of our sales advisors who will be happy to help on 01530231111
