Airflow Control - VAV and CAV

Circular air terminal units for variable air volume systems with low airflow velocities, suitable even with unfavourable upstream conditions

• Effective pressure measurement not with a tube, but by means of the damper blade
• Effective pressure transmission through effective pressure channel in the shaft
• Terminals with protective cover, no junction box required
• Any airflow direction if dynamic transducer is used
• Suitable for airflow velocities of 0.5 – 13 m/s
• Compact dimensions allow for use in restricted spaces
• Plug-and-play solution in conjunction with X-AIRCONTROL room control
• Exact measurement even with low airflow velocities
• Any installation orientation even with static transducer
• Closed blade air leakage to EN 1751, at least class 3
• Casing air leakage to EN 1751, class C
• Volume flow rate range 1:25

Optional equipment and accessories

• Acoustic cladding for the reduction of case-radiated noise

• Secondary silencer CA (for Germany and Switzerland), CAH (for EMEA) or CF for the reduction of air-regenerated noise
• Hot water heat exchanger WL and electric air heater EL for reheating the airflow

Circular, mechanical self-powered controllers for insertion into ducting, for the quick and easy balancing of constant volume flow rates in ventilation and air conditioning systems

• Unique damper blade edge for acoustic optimisation
• Simple and quick commissioning on site
• Range of volume flow rate setpoints for each nominal size
• Precise and simple setting of volume flow rates using a scale
• Best accuracy among controllers for insertion
• Suitable for low airflow velocities from 0.8 m/s
• Any installation orientation; maintenance-free

Adjustment devices for the service and commissioning of VAV terminal units. To display current values and parameters and for functional testing.

• Display of actual and setpoint values
• Display and changing of parameters and operating modes
• Simple connection to the service socket of the controller or to a terminal in theswitch cabinet
  
• Easy operation
• Portable devices for use on site
  

Circular self-powered volume flow controllers for the control of supply air or extract air in constant air volume systems

• Volume flow rate can be set using an external scale, no tools required
