Coolerado has launched its M50 Downflow air conditioning unit delivering an Energy Efficiency Ratio (EER) above 40 when used as stand-alone and above 21 when working in concert with DX Roof Top Units (RTU). The company claims the M50 Downflow line was designed for easy installation on commercial roof curbs.
The new Serco ATEC™ HVLS fan features advanced technology and design elements to distribute more air with less energy consumption than other big fans in the market, according to company officials. The Serco Advanced Technology for Environmental Control HVLS fan, or the ATEC HVLS fan, features an optimized five-blade profile, which translates to more airflow while conserving energy. The ATEC’s refined airfoil shape results in less drag, which in turn, equates to greater circulation and employee comfort.
Lennox has expanded its light commercial Raider® rooftop unit line to include new 7.5- to 12.5-ton models, adding to its existing offering of 3- to 5-ton units. Designed for compatibility with many replacement installations, Raider units are built to fit the most curb sizes virtually eliminating the need for an adaptor curb on many replacement jobs. Available in gas/electric and electric/electric models, 3- to 12.5-ton units offer efficiency levels of up to 13 SEER, 11.5 EER, and 13.2 IEER.
