F2260

The walls of a cold room are constantly subjected to strains caused by pressure variations, either from inside or from outside.

The valves FERMOD patented allow it to balance internal and external pressures through venting

A - THE MECHANICAL ELEMENT

The outside of the valve is made of a support profile, mobile flaps made of anodized aluminium and positioned by two composite boxes, all this protected by a cover made of shock polystyrene. The two mobile flaps consist of anodized aluminium plates and elastomer to ensure tightness.

This unit is fixed to a tubular crossbar made of anodized aluminium and equipped with a grill on the inside.

B - THE HEATING ELEMENTS

A heating cord wrapped around the crossbar, ensuring it remains frost-free.

An independent heating cord heats the mobile flaps seat. The heating cords require a supply of 220 V with earth connection and a power of approximately 185 Watts.

The connection is made directly into a composite box outside the cooling chamber.

Two thermal contacts control the temperature of the tube and the mobile flaps seat and are suitable to connect to an alarm device.
