Packaged rooftop units
RQ Series packaged rooftop units are engineered for high efficiency and energy savings. Double-wall, rigid-polyurethane-foam-insulated cabinet construction and direct-drive backward-curved plenum fans allow quiet, energy-efficient airflow with high static-pressure capabilities. RQ units are available as air-cooled condenser packaged rooftop units, air-source, water-source, or geothermal heat pumps, 100-percent-outside-air units, and chilled-water or non-compressorized air handlers. Heating is available in high-performance hot-water, steam, electric, and gas-heating configurations. They are available in capacities from 2 to 6 tons.

Duct liner
AP Coilflex duct liner is now available in 11/2-in. thickness. The fiber-free, elastomeric-foam duct liner is ideal for air-handling systems, variable-air-volume units, ducts, and other air-system components requiring condensation control and resistance to moisture, damage, or heat gain. AP Coilflex duct liner reduces the noise generated by fans and air movement, making it especially effective for schools, hospitals, and commercial and government buildings where good acoustics are important.

VFD shaft-voltage test kit
The AEGIS Shaft Voltage Test Kit is designed to make measuring and documenting variable-frequency-drive- (VFD-) induced voltages easy. Motors controlled by VFDs are vulnerable to electrical bearing damage. Although specifiers may choose motors that are equipped with shaft-grounding rings, the shaft-voltage test kit may be used in retrofit applications while there still is time to head off damage and downtime. The kit includes a specially tipped probe and a portable oscilloscope.

Pollution-control units
Grease Grabber Triple Play and Power Play pollution-control units are designed to eliminate smoke and grease particles from commercial kitchen exhaust systems, with odor-control modules that eliminate or reduce odors to acceptable levels. The Grease Grabber Triple Play features a three-stage mechanical filter coupled with activated-carbon panels to remove odor molecules prior to discharging the air. The Grease Grabber Power Play’s permanent electrostatic collector section removes grease and smoke particles from an air stream, while its integrated self-cleaning wash sequence allows for low maintenance and constant performance.

Ceiling-mount air conditioner
The CMW30 water-cooled, ceiling-mount air conditioner is designed for computer server rooms and other applications with dense heat loads, but where an air-cooled model cannot be used because of a lack of space. Its cooling capacity is rated at 29,400 Btuh total and 22,000 Btuh sensible. The self-contained CMW30 is only 20-in. high, enabling it to fit above a drop ceiling. No external condensing unit is necessary. The unit features an integrated energy-efficiency ratio of 17.0.

Air and dirt separator
Spirovent is a full-flow combination air eliminator and dirt separator for boiler and chiller systems. It uses a patented coalescing medium to provide unsurpassed efficiencies compared with centrifugal air separators and eliminates the need for side-stream filters. Spirovent eliminates routine maintenance to vent and purge, allows for a review of chemical treatment, and can result in energy reduction through improved heat transfer and reduced pump power. The units are available through 36-in. pipe size and flows of more than 30,000 gpm for both stand-alone and central-plant systems.

Watertight duct smoke detectors
NEMA 4-rated InnovairFlex watertight duct smoke detectors operate in challenging conditions without the need for bulky enclosures. They can operate in airflow speeds from 100 to 4,000 fpm, temperatures from -4°F to 158°F, and humidity from 0 to 95 percent (non-condensing). They feature a watertight, UV-resistant housing that provides protection against falling dirt, rain, windblown dust, and splashing and hose-directed water.

In-floor chilled beams
In-floor Active Chilled Beam, an energy-efficient perimeter heating and cooling solution, combines the benefits of underfloor air distribution (UFAD) with water heating and cooling efficiencies. In-floor beams provide the energy savings and capacity of an overhead chilled beam while avoiding potential damage from leaking water lines and condensation. The beams simplify UFAD design by reducing the amount of equipment under the floor and improve perimeter zone aesthetics by replacing diffusers with a linear grille.
