The UV-Com™ Control Panel from UV Resources provides a means of monitoring multiple Ultraviolet “C” (UV-C) fixtures installed in individual air handling units (AHUs). According to the manufacturer, the UV-Com easily automates the conventional means of “manually checking” that lamps and ballasts are operational and communicates this lamp status to most BAS and BMS. A single UV-Com control panel can simultaneously monitor up to eight separate UV-C fixtures. Multiple UV-Com panels can be linked together in a daisy-chain sequence in order to monitor as many individual UV-C fixtures as necessary.
Cummins Power Generation has developed a new line of all-diesel generator sets to help small businesses such as gas stations, grocery stores, health clinics, telecommunication facilities, and more remain open and operational even during extended power outages and in extreme weather.
NexRev Inc. says it has developed a new solution to deliver operational cost savings to multisite facility owners. DrivePak Applied combines NexRev’s DrivePak variable flow retrofit technology with its Freedom energy management and control system. The company uses these tools to implement strategies that improve operating efficiency on an expanded range of applied HVAC equipment including chillers, cooling towers, pumps, and air handling units. According to NexRev, customers can realize an attractive ROI with guaranteed results, and flexible procurement options are available to get projects funded, deployed and saving money as soon as possible.
The new EconomizerPro™ HVAC Monitoring Systems can record data from commercial rooftop units to find out if they are wasting energy. The system is simply added on to the unit. According to the manufacturer, it then uploads operational data to the cloud, where data is analyzed by sophisticated algorithms, identifying about $3,000 per year, per unit in wasted energy.
MovinCool®, a brand of DENSO Corporation, unveiled a new Climate Pro™ 18 portable heat pump, which combines both cooling and heating capabilities in a single, self-contained unit. The company says the compact system is 13% smaller and 22% lighter than other comparable heat pumps, yet it offers significantly higher performance. The Climate Pro 18’s cooling capacity is 14,600 Btu/h, the heating capacity is 13,700 Btu/h, and the minimum operating temperature with plenum is 24ºF.
Baldor Electric Company says it has introduced a new adjustable speed direct drive cooling tower system that improves reliability, reduces maintenance, runs quieter, and saves energy. By combining the technologies of the laminated finned frame Baldor-Reliance® RPM AC motor with a high-performance permanent magnet rotor design, this power-dense motor and power-matched adjustable speed drive replaces the right-angle gearbox and jack shaft installation found in many conventional industrial process cooling towers.
B&K Precision launched its latest multi-range DC power supply, the model 9111, expanding its 9110 multi-range supply offering. With constant voltage (CV) and constant current (CC) modes, the 9111 automatically recalculates voltage and current limits for each setting to deliver any combination of its 60 V/8 A output range within 180 W. The new DC power supply is suitable for a wide variety of uses in electronics manufacturing, service and repair, and engineering labs.
US EPA Tier 4 Final certified mobile generator sets with 150 kW to 275 kW power outputs are now available from Cummins Power Generation for the rental market. Cummins officials said the company conducted extensive field research to develop a reliable product to meet the latest emissions regulations. The mobile generators have been validated and are now available to rental operators and customers.
Berner International Corp. has introduced a patented Venturi-style heater design, which the company says will offer a more aerodynamic, electric heated air curtain with improved air performance efficiency by up 40% The VTH electric heater combines a hemispherical heating element array with an innovative mounting strategy at the blower inlet. The patented design uses the Venturi effect to draw air through the heating element via the blower inlet before it enters the discharge airstream. The discharge airstream velocity remains unobstructed in a near 100% efficient heat transfer, full laminar pattern for an optimum aerodynamic performance. Company officials said that this creates a near perfect environment-separating air seal across any open doorway while providing auxiliary heat, as needed.
Danfoss says it has developed the new TU with F-charge TXV to help OEMs meet the new U.S. Department of Energy commercial refrigeration energy efficiency standards. The new F-bulb charge delivers low superheat in low- and medium-temperature refrigeration ranges, includes asymmetric ballast material that is proven to deliver more stable temperature control and, like all Danfoss TXV bulb charges, is HCFC-22 free.
From a missing pipe hanger three floors down to steam traps past their prime, these stories show how steam system problems can originate inside the boiler room or far beyond it. Read more in February issue.
