10.0 Winter seal damper assembly
The new Brivis Iceberg Cooler has a new and unique mechanism, which is adjustable louver
constructed in the top of the Acoustic Cooling Chamber. The can be driven closed and prevents
heat loss from the building when the unit is not in use.
An electric motor drives the louver blade to the open and close position pending if the unit is in
or not in use.
The motor that drives the winter seal damper assembly is 240 Volts controlled through a geared
cam shaft and switch.
The motor is powered to open on one switch circuit, and powered to close on another.
The cam shaft causes the switch contacts to open, stopping the motor and mechanism at the
correct position, whether the motor is to be driven forward or in reverse.
