DESCRIPTION OF THE VALVE
It is heated, mechanically operated valve, with two water tight mobile flaps, allowing air flow in either direction.

The mobile flaps seat heated by an independent heating cord. The heating cords require a supply of 220 V with earth connection and a power of approximately 160 Watts.
The connection is made outside the cooling chamber, directly into a composite box.
Two thermal contacts control the temperature of the tube and the mobile flaps seat and are suitable to connect to an alarm device.

Working utilisation: -40°C to +30°C.
