1 I Fan Powered Terminal Unit VARIABLE VOLUME PARALLEL FLOW

2 Fan Powered Terminal Unit Variable volume parallel flow Product Overview Variable Volume/Parallel Flow Fan Powered Terminal Units Honeywell parallel fan-powered terminal units are designed to provide superior comfort by intermittent parallel fan operation.conditioned primary air is varied during cooling while the fan cycles on during heating. Parallel fan-powered terminal units allows for recovery of waste heat from the return plenum and a potential reduction in central fan energy, thereby lowering operating costs. In the heating mode with fan energized parallel fan-powered terminal units improve air circulation through better diffuser performance. Benefits of Variable volume Fan Powered Terminal Units The primary air valve is sized for cooling demand similar to single duct terminal design requirements. The recirculating air section is typically sized at 50% of the maximum primary air valve demand which results in lower noise, lower unit cost and reduced energy when compared to constant volume terminals. Construction Compact, durable zinc-coated steel casing means reduced ceiling plenum space requirements and protection from corrosion. Terminal casing is internally lined with fiberglass insulation. The insulation s high density skin provides erosion resistance while effectively attenuating noise. Insulation meets requirements of UL181 and NFPA-90A Proven reliable primary air section with heavy gauge damper and low leakage blade seal. Honeywell terminals come standard with SCR fan speed control for efficient, quiet adjustment of fan capacity. Electric motors are specially designed to operate with SCR controls ensuring reliable maintenance free operation. Fan motor is isolated from the blower housing to reduce noise. Additional vibration isolators and heavy duty motor mounts are provided on large unit sizes. Energy efficient, fan motor is designed to meet consistent torque specifications providing reliable and repeatable performance. ECM - Elecrtonically Commutated Motors are available as an option. Large removable bottom access panel provides access to the interior of the unit for cleaning, inspection and service. Quality Assurance Each Price fan powered terminal unit receives a full operational check before shipment and arrives factory calibrated in accordance with project specifications. This means costly labor and setup delays are avoided. Options: ECM energy efficient motor option Discharge attenuator section (DAS) for reduction of discharge noise Inlet attenuator section (IAS) for reduction of radiated noise Merv 8 and 13 filter bank for enhanced filtration of recirculated air Hanger brackets and spring isolation
