    With its powerful motor and certified “true” HEPA filtration, the Amana brand AHEPA can enhance the indoor air quality of an entire home, company sources state.

    With an activated carbon pre-filter and optional carbon VOC after-filter, the AHEPA removes lint, unpleasant odors, dust (atmospheric, household and coal), dust mites, insecticides, pollen, mold spores, fungi, bacteria, cooking smoke and grease, pet dander, and tobacco smoke particles — all without creating static pressure in a home's air distribution system.

    A strong motor, it delivers between 245-560 CFM of filtered air. The Amana AHEPA uses a powder-painted, heavy-gauge steel cabinet that can be mounted free-standing, on walls or ceilings. | www.amana-hac.com

    American Standard

    American Standard introduces the AccuClean whole-home air filtration system. Some product highlights include:

    • Removes up to 99.98% of allergens from the filtered air

    • Catches particles down to .1 micron in size

    • Eight times more effective than the best HEPA room appliance

    • 100 times more effective than a standard one-in. throwaway filter or ionic-type room appliance

    • Reusable filter can be cleaned by vacuuming.


    Aprilaire introduced a steam humidifier specifically designed for residential environments where evaporative technology is not practical to employ.

    The Aprilaire steam humidifier will produce the steam necessary on demand and then use the HVAC system's blower to deliver the steam throughout the home.

    For the HVAC Contractor, the Aprilaire Model 800 Steam Humidifier opens up additional market opportunities and combines easy installation and minimal maintenance.

    Special benefits of the Model 800 Steam Humidifier:

    • High capacities of up to 23 gallons per day — A single unit provides capacity for many larger residential applications.

    • Easy and economical to maintain canister/electrode technology. Simply replace the canister, usually on an annual basis.

    • More efficient; provides humidity when you need it — Operates on a call for humidity. Controlling humidity is no longer dependent on a call for heat from the thermostat.


    Danfoss introduces the Performer® VSD, a variable-speed compressor designed for the residential market that integrates power electronics, scroll technology and advanced software.

    The Performer VSD mates the first high-capacity scroll compressor for R-410A refrigerant with a variable-frequency drive to deliver exactly the capacity required for cooling every minute of the day, setting a new performance standard.

    Ideal for all climate zones, the Performer VSD offers exact temperature control with +/-0.2F. Comfort is further enhanced by the unit's low vibration levels and quiet operation, with virtually no cycling noise at night. | www.danfoss.us

    Fieldpiece Instruments introduces the wireless HVAC guide® system analyzer, model HG3 and wireless transmitter, model ET2W. This new system turns any of the Fieldpiece accessory heads into wireless test meters. Technicians now simply attach accessory heads to the test points and collect and analyze all the test data on the HG3. As the tech makes adjustments to the system, the HG3 will continue to collect the data in real time for easy analysis. Up to 12 parameters can be measured wirelessly at one time and sent to the HG3 for live viewing and analysis.

    The Fieldpiece HG3 is a wireless system analyzer that leads technicians step-by-step through critical tests including: Target Evaporator Exit Temp, Target Superheat, Superheat, Subcooling, Combustion, and the CheckMe!® diagnostics program. The HG3 is the third generation HVAC Guide System Analyzer and now includes tests for CFM and Data Logging, and also has a Display switch position to easily read results directly from any accessory head. | www.fieldpiece.com


    The Goodman DMH900 air filtration unit removes, reduces and inhibits allergens, atmospheric dust, odors, biological pollutants and chemical contaminants throughout the entire house — all in a single-unit with reduced installation time, no external ducting required.

    The true HEPA-certified whole-house DMH900 uses three-stage IAQ technology: A MERV 11 filter removes 99.97% of all air contaminants; UVC Germicidal Lights sterilize mold, fungus and bacterial growth; while a CinQuartz® Photo-Catalytic Oxidation (PCO) decomposes organic materials into basic molecules such as carbon dioxide and water.

    Versatile installation options for the Goodman DMH900 air cleaner include duct-mounted, collar-mounted or free-standing. Pre-punched openings and a mounting template ease installation. | www.goodmanmfg.com


    Honeywell introduced TrueEASE, a complete family of evaporative humidifiers that reduce contractor installation time and help improve the profitability of a contractor's business, company sources state. The advanced design and patent-pending features of the TrueEASE™ whole-house humidification system offers maximum versatility and efficiency — all significant features for installers and homeowners alike.

    The patent-pending interchangeable bypass eliminates the need to disassemble and rebuild the humidifier if the bypass direction needs to be changed. The mounting screws located around the perimeter of the humidifier make single-step installation possible rather than mounting a separate frame assembly.

    TrueEASE cycles water and air through the system only when humidity is needed; using up to 50% less water. It also helps save energy by eliminating the constant cycling of air. | www.forwardthinking.honeywell.com

    Lennox Commercial

    The Humiditrol® dehumidification system from Lennox reduces humidity levels, regardless of room temperature, for ideal comfort every day of the year. The system's unique dehumidification-on-demand design removes moisture based on humidity levels, not temperature, for an easy and efficient way to create a better indoor environment. By maintaining relative humidity levels between 30% and 60%, the Humiditrol system helps reduce the spread of allergens, including mold, mildew and dust mites that can lead to absenteeism and long-term health problems such as asthma.

    The Humiditrol system is available for Energence® rooftop units as a factory-installed option, including an advanced system, available for 3- to 5-ton Energence rooftop units, that uses up to 20% less energy while providing the same dehumidification performance as comparable systems. Operation is driven by the Prodigy® unit controller which initiates dehumidification when the room temperature is satisfactory but humidity is above the desired setpoint. The Humiditrol system is also available as a field-installed accessory for S-Class™ and T-Class™ commercial air conditioner and heat pump split systems. | www.lennoxcommercial.com

    Ritchie Engineering

    The Yellow Jacket® Accuprobe UV, by Ritchie Engineering, uses heated sensors or UV technology (or both at the same time) to detect HFC, HCFC and CFC refrigerants, including SNAP approved hydrocarbon blends. The AccuProbe UV features low, normal and high sensitivity levels with visual and audible signals, and a UV light at the tip, which allows technicians to see dye in a system. The audible alert, which can also be muted, increases in frequency and duration as concentration increases. The AccuProbe UV also features a SmartAlarm LED which quickly shows how big or small the leak on a scale of one to nine. Other features include a long life, stable sensor, instantaneous response time, quick clearing from large amounts of refrigerant, automatic calibration and reset to ambient, and a low battery indicator. | www.yellowjacket.com/disb


    The Ruskin MiniVentilator comes in two sizes — nominal 450 and 750 cfm. It includes a low-profile, compact design with 110 volt electrical connection, and can be installed with horizontal or vertical duct configuration. The cabinet is fully insulated and made of durable, powder-painted steel. This product is perfect for use in hospitals, assisted living facilities, classrooms, and small office spaces. The MiniVentilator uses an Airxchange AHRI-certified enthalpy wheel to transfer latent as well as sensible energy from the exhaust air to the incoming outside air. | www.ruskin.com


    Trane introduces the FreshEffects energy recovery ventilator. The unit features:

    • Cleaner, healthier indoor air: Exchanges stale indoor air for an equal amount of fresher outdoor air.
