Application
Pressure changes either inside or outside a low temperature coldroom will cause large forces to act on wall and roof panels.

Pressure decrease occurs as the room is brought down to working temperature. Panels can be deflected inwards and doors may be difficult if not impossible to open.

Pressure increase occurs as evaporator fans switch on after defrost or produce is loaded. Panels can be deflected outwards and doors forced open.

The Loheat PRV75 Pressure Relief Valve equalises internal and external pressures to reduce the possibility of these problems occurring.
