  Model QPT - Fan Powered Parallel Air Terminals  
       
 


Model QPTS
Parallel Basic Assembly

Application

  • Parallel type, fan assisted air terminal
  • Maintain space temperature with primary flow control and intermittent fan operation for energy reclamation from warmer ceiling plenum during heating cycles.
  • Control strategies using pneumatic, analog, or direct digital control (DDC) systems
Product Features
  • Efficient, 3 Speed motor (permanent split capacitor) with thermal overload protection allows horsepower change for greatest potential of energy savings. 120 or 277 vac, 1ø
  • Solid state speed controller with factory calibrated minimum voltage setting for precision air flow adjustment.
  • 18 & 20 gauge zinc-coated steel design for rigidity.
  • 1" dual density thermal / acoustic internal insulation (NFPA 90A & UL 181)
  • Easy to install and service – all controls located in one convenient location for single point electrical connection.
  • Swing-down fan access panel
  • Steel control enclosure, screw attached cover. Left hand position is standard.
  • 90º inlet damper & perimeter seal limiting leakage to <1% of max rated flow at 3" w.g. inlet static pressure.
  • Patented Velocity Wing primary flow sensor measures flow to ±5% accuracy regardless of inlet conditions. Highest velocity pressure amplification means high turn down with high accuracy.
  • AHRI 880 certified performance / ETL listed (UL 1995).
  • Accepts flanged discharge duct connection
Options
  • Q5 radiated sound elbow
  • Hinged front control enclosure cover
  • Internal Insulation - 1/2" or 1" foil-faced glass fiber insulation with metal taped edges meeting ASTM C665, double wall construction, Lo-Temp casing construction, 3/8" fiber free closed cell foam insulation, no insulation, see page A-11.
  • Slip & drive cleat discharge collar
  • 1" Throw-away filter & filter rack
  • Unit mounting brackets (field installed)
  • Electrical component options – line voltage disconnect switch, power fusing, 3-speed manual motor selector switch, electric damper actuator (24vac) for use with DDC controls, fan relay for on-off function, 24vac step down transformer
  • Digital, analog, or pneumatic control systems

Model QPTW
Parallel Hot Water Heat

Application

  • Parallel type, fan assisted air terminal with integral hot water heating coil
  • Provide hot water heating to perimeter spaces during occupied periods and night cycling temperature control with central fan systems shut down
Product Features

Same as Model QPTS plus:

  • 1 or 2 row hot water coils
  • 1/2" O.D. copper tubes, .016" wall thickness, mechanically expanded in fins. Manifolds are minimum .028" wall thickness.
  • Aluminum corrugated fins with rippled edges, .0055" thick, 10 per inch.
  • Designed for maximum heat transfer and low water pressure drops using single and multi-circuited designs.
  • Performance data per AHRI Standard 410
  • Factory pressure tested for leaks at 300 psi, burst tested at 450 psi, ambient temperatures.
  • 20 gauge galvanized sheet metal casing with 18 gauge end plates
  • “Slip & Drive” connection provided for metal discharge duct connection
  • Connections are male solder headers.
Options

Same as Model QPTS plus:

  • Right hand or left hand coil connection – factory configured
  • Coil clean-out access door
  • “Steam” construction available. Contact your local Anemostat representative.

Model QPTE
Parallel Electric Heat

Application

  • Parallel type, fan assisted air terminal with integral electric heating coil
  • Provide electric resistance heating to perimeter spaces during occupied periods and night cycling temperature control with central fan systems shut down
Product Features

Same as Model QPTS plus:

  • Integral electric heating coil with nickel-chrome resistance wire
  • Primary, auto reset thermal cutout
  • Fan interlock relay for proof of air flow
  • 24vac Class II transformer (unfused) as required for 24vac control systems
  • PE switches for pneumatic control systems
  • Magnetic de-energizing contactor per step
  • Accepts flanged discharge duct connection
  • Left hand control and heater cabinet position are standard
Options

Same as Model QPTS plus:

  • Door interlocking disconnect switch, non-fused
  • Air flow switch in lieu of fan interlock relay
  • Power fusing (fuses & fuse blocks)
  • Manual reset secondary thermal cutout
  • SSR modulating controller
