Larson Electronics released an explosion proof portable air chiller with a 34-gallon water tank. The EPF-AC-30 from Larson Electronics is a hazardous location cooler that combines a fan and dry mist technology to cool Class 1 Division 1 work areas that do not have access to traditional air conditioning.
Weil-McLain says it is now offering its most advanced high-efficiency condensing boiler. The new 95% AFUE Evergreen boiler is designed with simple controls and flexible functionality for multiple applications.
Johnson Controls introduced its Coleman® Outfitter™ Ultra High Efficiency Packaged Unit. The company says the unit delivers the highest AHRI-listed efficiencies in the industry — up to 18.1 SEER and 14.35 EER — due to the combination of the unit’s two-stage compressor, variable-frequency drive, high-efficiency indoor/outdoor coil, and premium-efficiency indoor/outdoor motor. A common footprint allows for easy installation on a curb, slab, roof rack, or frame.
Johnson Controls launched the new York® Prestige™ rooftop units, which match the footprints of other manufacturers’ units. The new design reduces installation complexities and saves contractors time by eliminating the need for a curb adapter, which is typically required when a new unit does not identically match the existing unit footprint.
Cambridge Engineering has introduced a new line of Blow-Thru® Direct Gas-Fired Space Heaters designed to efficiently and safely heat smaller commercial and industrial facilities. The new line of space heaters, called the Cambridge SA-Series, uses the same technology as the larger ultra high-efficiency Cambridge S-Series, but is sized for smaller applications.
Leaning on experience and data from various K-12 cities and projects, the author pursues some less conventional design approaches. They may revolve around radiant heating and/or cooling, but depending on school size and other factors, the smart use of heat recovery, DOAS, and improved central plants could also put a project on the HVAC honor roll.
