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 promotes the introdution of moisture in the freezer and may induce frost formation after the air
intake tube to which 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 that without ice formation in
the valve well.
In normal operation, this vlave 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 properly after cleaning.
After stopping the freezer completely, remove the valve foam to dry. Before restarting the freezer, replace the dry foam.
After CO2 or LN2 injection, it is necessary to dismantle the decompression valve and reposition the inner circular silicone
membrane properly in order to ensure the correct sealing inside of the valve.
Heating door seal :
Froilabo freezers are equipped with a
heating door seal
to prevent the formation of ice and thus maintain an optimal
seal of the freezer.
Refer to the "Maintenance, cleaning and decontamination" section for cleaning the door seal
.
Air filter :
In order to maintain the cooling performance of the device and to preserve the compressors lifespan, an air filter is
placed in front of the condenser.
It is necessary to dust or wash this filter as frequently as necessary.
A device must never operate without a filter.
Clamping handle :
The device has a progressive tightening handle. Its double-action makes it easier to open and close the door. The
freezer door can be locked thanks to the key lock located on the side of tha handle.
