Insulated saddles and clevis-hanger covers
New CoolDry insulated saddles and matching Wraparoos clevis-hanger covers provide water- and moisture-resistant insulation and jacketing. The chlorofluorocarbon- and hydrochlorofluorocarbon-free phenolic-foam insulation has excellent compressive strength (3.75 PCF and 5 PCF) and meets rigid 25/50 flame/smoke ratings, while the vapor-barrier jacketing with self-sealing tape is zero-permeance-rated. A unique partial-bottom ribbed saddle secures the CoolDry system, while the bright-white polyvinyl-chloride Wraparoos clevis-hanger cover protects the saddle and cleans easily with a damp cloth.

The new Eon 42 motor is an energy-efficient alternative to the standard permanent-split-capacitor motor found in many fan coils and blower-deck applications. The motor saves up to 56 percent of the electricity consumed by the motor. It is easily installed and is available in a wide range of horsepower ratings, voltages, and mechanical features. Its benefits include:
- Efficiencies exceeding 78 percent
- Low-voltage AC or DC thermostat inputs allowing use of existing system controls.
- Ability to be retrofitted into variable-speed applications.
The motors are designed for direct-drive blower applications 120V or 208/240/277V AC single-phase input, 50/60Hz. They are available in 1/15 hp (low speed only) as well as 1/8 hp and 1/4 hp (high and low speed).

Light-commercial rooftop units
AAON RQ series rooftop units (2 to 6 tons) feature double-wall rigid-polyurethane-foam insulated cabinet construction and direct-drive backward-curved plenum fans allowing for quiet, energy-efficient airflow with high-static-pressure capabilities. Standard RQ series features include stainless-steel piano hinges, color-coded wiring diagrams, labeled components, and isolated controls and compressor compartments for ease of maintenance. Available options include single-zone VAV, high-efficiency variable-speed fans, variable-capacity compressors, energy-recovery wheels, and economizers. RQ series units are available with efficiencies of up to 19 SEER; as air-cooled or water-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. Visit http://aaon.com/product.aspx?id=1 for more information.

Digital temperature interlock
Greenheck’s new digital temperature interlock is designed to automatically start kitchen-hood exhaust fans and keep them running while heat is being generated from cooking appliances. Acting as a backup to a manual control, the interlock will override the switch and start the fans once heat is detected, ensuring safety in the event an operator fails to manually turn on the fans. The interlock enables quick and accurate temperature adjustment via a digital controller with an LED display that can be remote mounted, allowing easy access and accurate control when making seasonal adjustments to the temperature setting. The interlock complies with International Mechanical Code 2009 section 507.2.1.1, which requires interlock between exhaust fans and cooking equipment.
