Availability of different types of actuators opens the possibility to implement various additional capabilities. Quick damper positioning can be chosen as well as safety opening or closing trip after power supply interruption.

Galvanized steel

The AV unit housing of the OPTIMA-R-PC...BM as well as the control damper blade is made from galvanized sheet steel making it tough and durable.

OPTIMA-R-PC...BM is a variable pressure controller with or without an insulation. It is commonly used to control the air pressure in a ventilation system and is available in different sizes. The units are ideal for single zone pressure control in supply or return operation mode. OPTIMA-R-PC...BM is commonly installed in spaces with requirement to keep certain air pressure conditions like e.g. laboratories, industrial plants and health care premises.

VAV unit housing is made from galvanised sheet steel. The factory adjusted operation parameters on the controller can be re-adjusted on site via analog or binary signals as well as via bus communication.
