RAVAV-Q

The RAVAV-Q regulator is design for variable air volume ventilation systems and is an important component for optimizing air flow into the indoor premise for energy savings.

 

The regulator casing is made of Z275 galvanized sheet. Optionally, it is possible to use the 1.4301 stainless steel to build the casing. Inside the casing profiled and insulated (mineral wool) damper blade (non-airtight). The actuator is installed on the control unit casing so as to allow for thermal insulation of the system. The regulator is also available in the version insulated housing with 50 mm of mineral wool enclosed in galvanised steel shield. The measuring system based on aluminium impact pressure tubes and pressure relieve stub pipes ensures reliable measuring of the air flow. Sensor, digital control unit and actuator are integrated in one device.

​

The actuator adjusts the damper position, the control unit compares the current air flow rate with the set value and the sensor turns the differential pressure value into electric signal. It is possible to change standard controller to solution with fastrunning actuator, static pressure sensor, etc

Characteristics

• High air flow measurement accuracy

• Casing tightness is class C as per EN-1751:2014-03

• Operating temperature range from 0 to 50 [˚C],

• Differential pressure range measured before and after the regulator 50-1000Pa.

• Possibility to measure current air flow parameters using external micromanometers
