Heated pressure relief valve:
The pressure relief valve allows a balance of pressures between the inside and the outside of the freezer which makes
it easier to open the door.
Frequent doors opening favours the introdution of moisture in the freezer and may induce frost formation after the air
intake tube where the valve is attached. A calibrated foam is placed into the air intake tube to limit this phenomenon.
Froilabo freezers are equipped with a heated pressure relief valve allowing a quick return to the ambient pressure inside
the enclosure, either after a door opening or after the injection of CO
2
or LN
2
, and without ice formation in the valve well.
In normal operation, this valve does not require any maintenance.
The heating element of the valve starts to heat when the temperature inside the freezer reaches -15 ° C.
However, check regularly (depending on use) that the pressure relief valve (located on the side of the device) and the
calibrated foam are working properly. Reposition it properly after cleaning.
