Chilled Beams and Induction Beams

Induction Beams and Chilled Beams receive a source of primary air at an inlet static pressure ranging from 0.2″ to 0.8” of WC. The beam distributes this air through a bank of specially designed aerodynamic nozzles and discharges the air at a high velocity into a mixing chamber. This creates a differential pressure which enables a draw of room air across a coil. This imparts either cooling or heating to the induced air as it passes over the coil. The primary air and induced air are mixed and discharged through a grille in a Coanda effect air distribution at the ceiling, soffit or low wall. This air circulates throughout the room and is gently drawn back up through the return section of the Induction or Chilled Beam grille. The total room air circulation is created solely by the induction principle within the terminal. This eliminates the need for an electric motor, its power source and the related maintenance. As a result, the Induction or Chilled Beam delivers the primary air to each space, is a very quiet and efficient way to provide superior IAQ and thermal comfort in a space.

Induction Beam Benefits


  • Code compliant Drain Pan can handle latent conditions & provide liability control
  • Capable of sensible only, fully condensing or hybrid systems.
  • Eliminate the fear of condensation forming on the beams coil.
  • System Cooling operates with fewer controls, no condensation sensors, when needed and doesn’t require a condensation switch to turn off the chilled water unlike a conventional chilled beam.
  • Building can have multiple water loops with different water temperatures to handle specific area requirements.
  • Entering water temperatures as low as 42°.
  • Qualifies for LEED points
  • Quiet Systems (NC14 to NC35 sound levels)
  • Made in USA

Lower Maintenance Costs


  • Lower Maintenance Costs
  • No wiring
  • No fans
  • No compressors
  • No moving parts to fail

Lower Construction Costs


  • Less equipment & piping cost due to drain pan
  • Less ductwork required
  • Higher cooling and heating capacities = fewer units
  • Fewer units = less copper piping & ductwork
  • Reduction in the size of the DOAS/AHU
  • Reduction in the size of the chiller/boiler
  • Smaller piping due to less GPM
  • No need for mixing valves or heat exchanger to keep water temperature above the dew point
  • Less controls and less complicated system
  • Reduced Air handler cost – No need for custom DOAS units

Lower Operating Costs


  • Decreased energy consumption at the Air Handler.
  • Air Handler can provide minimum ventilation since induction beams have greater capacity reducing the need to over ventilate to meet space loads
  • Save 25-35% on HVAC costs versus VAV systems.
  • Less GPM = Less pump energy
