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.
Flomatic Corp. introduced its new Model 80DICL-VFD, a special patent-pending submersible pump check valve for use with VFD control submersible pumps. According to the company, standard check valves will “chatter” and be noisy when a VFD goes to low flow, causing premature wear and eventual failure.
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.
The HSC Firepak™ from Armstrong features a compact design, which officials describe as a “plug and leave” design. The company also said it features readily available CAD drawings, specifications, dimensions, and pricing data.
Victaulic expanded its Vic®-300 MasterSeal™ butterfly valve line with a completely stainless steel option. The company says the new Series 461 stainless steel butterfly valve provides a cost-competitive option for the HVAC and potable water markets.
RBI has introduced the latest edition to its ultra-high efficiency condensing boilers and water heaters. The Infinite Energy2 (IE2) utilizes a state-of-the-art Radial Variable Circulation (RVC) stainless steel heat exchanger for maximum heat transfer and operating efficiencies of up to 98%.
Greenheck’s industrial dampers are heavy-duty, flanged-style frame dampers with various blade styles and pressure classes designed to control airflow and provide shut-off in HVAC and industrial process control systems.
The ABB Low Voltage Products division is offering a new line of heavy duty safety switches for commercial and industrial applications, meeting the necessary UL98, CSA, and NEMA KS-1 standards. The 600V and 200kA rated switches use the same globally rated bodies as ABB’s rotary-style switches, providing increased performance, reliability, and safety to the heavy duty market segment, according to ABB.
Groschopp Inc. has launched a family of brushless DC motor controls for its entire product line of BLDC motors and gearmotors. Designed to provide commutated power and variable speed control, the company claims these closed loop controls provide excellent speed regulation over a wide range of loads.
