Options

A full range of factory installed options are available, allowing for the air handler design that best suits each individual application.

Chilled Water Cooling

ARI certified type 5W, W, or WD coils provided with water modulating valve and actuator. Turbulators and various row, fin series, and valve options are available.

Cooling Only/Heating Casings

Cooling Only—Extended casing of solid double wall construction with foam injected insulation throughout the air handler.

Electric Heat—Nickel-chromium electric heating elements in individually fused circuits of 48 amps or less and with all necessary safeties. A full range of sizing options is available.

Natural Gas Heat-Two-Stage— Two-pass stainless steel tubular free floating heat exchanger has industrial type burner and combustion blower. Available with high, medium and low fire and UL and CSA approval.

Natural Gas Heat-Full Modulation—The heat exchanger drum, tubes and front and rear headers are constructed of corrosion resistant stainless steel. Available with high, medium and low fire and UL and CSA approval.

Steam Heat—ARI certified type NS coil with non-freeze steam distribution. Coils are pitched for drainage and are provided with steam modulating valve with actuator. High and low heat options are available.

Hot Water Heat—ARI certified type 5W coil mounted for drainage and provided with hot water modulating valve with actuator. High and low heat options are available.

Blank Sections

Four Foot Blank Section—Solid double wall construction with foam injected insulation. The blank section is located at the airflow discharge. Single point latching, hinged access doors are located on either side of the blank section. Final filter options are available for cooling only units.

Eight Foot Blank Section—Solid double wall construction with foam injected insulation. The blank section is located at the airflow discharge. Single point latching, hinged access doors are located on either side of the blank section. Final filter options are available for all units.

Fan Options

Standard CFM supply exhaust/ return fans—Available to meet standard airflow application needs.

Low CFM exhaust fans— Available to meet low leaving air temperature requirements.

Power Supply

Air Handlers are available with 460 or 575 voltage, 3 phase 60 hertz power supply.

Exhaust

No Exhaust—Air Handlers can be built for makeup air applications with no exhaust. Relief opening is sealed watertight.

100 Percent Modulating Exhaust Fan—A double width, double inlet forward-curved fan can exhaust up to 100 percent supply air. The fan operates when economizer damper is open greater than minimum position. Discharge dampers at fan outlet modulate in response to economizer damper position on Constant Volume (CV) air handlers.

100 Percent Modulating Exhaust Fan with Statitrac™ Control—

For both CV and Variable Air Volume (VAV) air handlers, the 100 percent modulating exhaust discharge dampers are modulated in response to building pressure. A differential pressure control system, Statitrac, uses a differential pressure transducer to compare indoor building pressure to atmospheric pressure. The FC exhaust fan is turned on when required to lower building static pressure to setpoint. The Statitrac control system then modulates the discharge dampers to control the building pressure to within the adjustable, specified deadband that is set at the Human Interface Panel.

100 Percent Modulating Exhaust Fan with Statitrac Control and Variable Frequency Drive— Provided with all the necessary controls to control/maintain building space pressure through a CV or VAV air handler. The Variable Frequency Drive (VFD) modulates the speed of the exhaust fan motor in response to building pressure. A differential pressure control system, Statitrac, uses a differential pressure transducer to compare indoor building pressure to atmospheric pressure. The 0-100% modulating relief dampers modulate in response to a signal from the unit microprocessor, based upon the space static pressure, and causes the damper to modulate open or closed as required to maintain the space pressure within the deadband.

100 Percent Modulating Exhaust Fan with Statitrac Control and Variable Frequency Drive and Bypass—Bypass control provides full nominal airflow in the event of drive failure.

Return

100 Percent Modulating Return Fan—A single width plenum fan with airfoil blade can relieve up
