Krueger Announces DOAS Unit:

The Krueger DOAS fan powered terminal unit uses a non-condensing cooling coil that is located on the induced air inlet of a series fan powered VAV terminal unit, with the primary air inlet sized for the zone ventilation requirements supplied from the DOAS unit.

  • Easily Applied to a Chilled Beam Specification - Krueger’s DOAS fan powered terminal unit uses the same primary pipes and ducting as a Chilled Beam system.
  • Minimum Static Pressure (Ps) Requirements - Active Chilled beams use induction nozzles to move air across the cooling coils, often requiring 1” Ps or more. The DOAS fan powered terminal unit has minimal inlet pressure requirements, less than 0.1” Ps.
  • Assures Minimum Ventilation Rates - By providing up to 4 settings of ventilation air utilizing a self contained pressure independent air volume controller, The DOAS fan powered terminal unit assures the proper amount of ventilation air at all times.
  • Earn “Green”/LEED Points - Using Krueger’s DOAS unit will earn you “green” points by its flexible design. Whether the occupant space expands or changes, the system can easily adapt.
  • Optional MERV 8 Filter - Earn a LEED point for providing the optional MERV 8 filter on the non-condensing cooling coil.
  • Lower First-Cost Compared to Chilled Beams – A Chilled Beam unit is installed over every occupied space, often costing several times what a ducted DOAS fan powered terminal unit will cost, with a single unit supplying several areas.
  • Energy Efficiency - ECM motors are utilized for optimum energy use and control.
  • Optional Reheat Capabilities – Optional hot water or electric heating allows for effective standard overhead heating eliminating the need for a secondary system.
  • Conventional Installation - Using standard diffusers, contractors will be able to install the complete system with no training or difficulty
