- Rectangular mechanical automatic controller
- Factory functional testing of each unit
- No on-site calibration required
- Units are essentially ready for commissioning after installation
Constant volume flow regulators facilitate commissioning in constant systems (CVS). The desired air flow is set at an external scale (RN/EN). There is no other complex or time-consuming calibration.
Even air distribution among the multiple air diffusers only occurs with the appropriate duct layout or after adjustment of the throttle dampers. Volume flow limiters for sliding into the air duct at each diffuser make sense, since both commissioning is easier and quicker and exceeding of the design criteria is prevented.
