Description

COMPACT VAV SOLUTION FOR LOW AIRFLOW VELOCITIES

Circular air terminal units for variable air volume systems with low airflow velocities, suitable even with unfavorable 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 100 – 2550 ft/min
  • 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

Application

  • Circular VAV terminal units for use in ventilation and air conditioning systems
  • For virtually all control, inductor and shut-off tasks in the supply air or extract air area
  • Also for unfavorable upstream conditions at low airflow velocities
  • Closed-loop volume flow control using an external power supply
  • For variable or constant volume flow systems
  • Shut-off via override control by others

Special features

  • High effective pressure signal at a small angle of attack
  • Factory set-up or programming and aerodynamic function testing
  • Volume flow rate can be measured and subsequently adjusted on site; additional adjustment tool may be necessary (depending on the variant of the control component)
  • Effective pressure monitoring tubeless via damper blade
  • Effective pressure transmission through effective pressure channel in shaft
  • Any direction of flow with dynamic transducer
  • Any installation orientation, even with static transducers
  • Suitable for airflow velocity of 100 – 2550 ft/min
  • Compact dimensions for use in confined ceiling areas

Nominal Sizes
