4000-Series Air Handling Systems Cooling, Energy Recovery .

4000-SeriesAir Handling SystemsCooling, Energy Recovery, Heating & PressurizationImproved indoor air quality – Helps diluteairborne contaminants helping exhaustsystems operate more efficiently.Superior ventilation - System can be designedto automatically modulate outdoor air volumefrom 20% to 100% to help meet ventilationrequirements in cold weather and decrease heatbuildup in warm weather.More consistent temperatures and lessstratification – Free ventilation cooling effectivelyhelps reduce indoor air temperatures to help keeppeople and processes productive.Improved efficiency and quiet operationfrom airfoil style fans.Customization - Broad range of sizes and options.Ease of management and control – Computerbased Intelligent Controls provide systeminformation easily and effectively.Cost savings – Heating systems deliver up to100% of the heat generated into the buildingresulting in energy savings.Installation flexibility and convenience - Heatingsystems require little to no ductwork. Theevaporative cooling systems do not requirecondensers, chillers, water towers or distributionpiping.Design flexibility with a variety of heating options Direct-fired burner, electric, hot water or : 100% OUTSIDE AIR ONLY

Features and Benefits of the CustomizableRAPID 4000-Series Air HandlerInlet HoodInlet hoods help minimize water entrainment into the air handler. Incoming airenters the air handler via an angled facecovered with birdscreen.An inlet plenum may be used in placeof an inlet hood.Inlet PlenumInlet plenums help minimize water entrainment into the air handler. Incoming air entersthe inlet plenum through three sides coveredwith moisture limiter media or optional metallouvers. With a sloped floor, the inlet plenumis equipped with drain outlets to the roof orpad for water removal.Filter SectionThe filter section cleans the outside air before itis delivered to the conditioned space. Variousfilters are available, including pleated, polyester,aluminum mesh, bag and cartridge.Instead of a filter section, a filteredmix box section may be used.Filtered Mix Box SectionTreating both outside and return air, filtered mixbox sections help clean the incoming air beforeit is delivered to the conditioned space. Variousfilters are available, including pleated, polyester,aluminum mesh, bag and cartridge. Damper options include manual positioning, summer ventilation economizer and automatic positioningbased on building pressure.

Mix and Match various combinations of optional sections to meetspecific design requirements. Create one of the greenest air handlersavailable today by combining filtration, energy recovery, a direct-firedburner and the standard backward inclined airfoil fan.Cooling CoilsA variety of mechanical cooling care available, including: Direct Expansion (DX) Coils - CoRow quantity, fin spacing, circuitfit the specific application. Chilled Water - Well suited for 1coil sizes and materials are availa Many other options, including aEvaporative cooling can be uinstead of cooling coils.Energy RecoveryStandard energy recovery modules are available for air flows up to 60,000 CFM (largercustom sizes also available). When the air handler is heating, an energy recovery moduleunit can help greatly reduce fuel consumption by using warm exhaust air to pre-heat theincoming outdoor air. During summer ventilation, during the use of a mechanical coolingsection or when defrost is required, face and bypass dampers may be used to divert outsideair around the energy recovery module. With a plate-style energy recovery module, exhaustair and incoming air pass each other in a cross-flow pattern, divided by thin metal plates.Sensible energy is transmitted from the exhaust air to the incoming air via conduction.There are several benefits of the plate-style exchanger over other types of energy recovery,including minimal wear and long life because there are no moving parts. In addition, theexhaust air will not cross-contaminate the supply air.Exterior Finish (Paint)Three standard colors are available for equipment exterior finish. Each color is representedbelow (actual color may vary due to print quality vs. product application). Colors areavailable for enamel or epoxy paint. The final external coating incorporates a high glosssolvent borne acrylic modified alkyd enamel.

An inletcone is used to streamline air flow into the fanwheel to help ensure full and even loading ofthe fan blades. Fan bearings have a minimumAmerican Bearing Manufacturers Association(ABMA) rating of L10 at 100,000 hours for longlife. Each fan is driven by multiple V-belt drivesconnected to the motor. Five discharge openings are available (top, bottom, left, right, end)for flexibility.In place of, or in addition to the directfired burner, electric, hot water or steamcoils can be used. Coils are factoryinstalled with the appropriate safetydevices.
