April 15, 2013 - The Blue E represents a redesign of Rittal’s Top Therm enclosure air conditioners, focusing on improving the energy efficiency of the units while maintaining cooling effectiveness. There are several elements that contribute to Blue E’s energy efficiency, Rittal says, the first of which is electronically commutated fans, which offer 30% energy savings when compared to AC fans. Blue E cooling units continue to feature nano-coated condenser coils, which allow dirt and debris to pass through without sticking. This, says the company, reduces maintenance intervals and maintains a higher level of performance. The Blue E controller, meantime, actively sample the enclosure’s interior air temperature and, when it is below 25C, it will shut off the internal fan. It will then activate the fan every 10 minutes to circulate the internal enclosure air and take a temperature reading, and repeat the process.

March 27, 2013 - Eaton has released the H-Max Series variable frequency drive (VFD), which claims to increase energy savings, lower utility costs and reduce emissions in commercial buildings. According to Eaton, customers whose HVAC systems do not yet use adjustable frequency drives to control motors can realize energy savings up to 45% over their current control method. Meanwhile, those already using an adjustable frequency drive solution can realize an additional energy and emissions savings of up to 10% by switching to an H-Max drive, it says. The H-Max series features insulated gate bipolar transistors (IGBTs), a real-time clock and calendar, and Active Energy Control, which helps customers design and operate HVAC systems. Users can see additional cost savings by tapering system requirements during off hours, weekends, and holidays.
February 22, 2013 - Tekmar Control Systems (Vernon, B.C.)—a Watts Water Technologies company—says its Boiler Control 284 is designed to operate up to four boilers to accurately maintain a target water temperature. The 284 operates both condensing and non-condensing boilers that are either modulating, single- or two-stage, and communicates with building automation systems (BASs). The system can be remotely monitored and adjusted through BACnet or Modbus communication. This connection makes it possible for installers and building managers to monitor boiler operation, plant and vent temperatures, system pressure, flow rates and pump operation using the BAS system interface. When no BAS connection is required, remote monitoring can be provided through TekmarNet Gateways. Tekmar says the 284 is designed to prolong the lifespan of the equipment; primary pump sequencing prevents downtime by automatically operating a second pump when a failure is detected. Other reliability features include pump exercising, equal run-time rotation, and boiler minimum and maximum temperature settings.
February 21, 2013 - ATCO Emissions Management has added heat recovery steam generators (HRSGs) to its line of gas turbine auxiliary equipment for the power, oil and gas, and cogeneration markets. The new HRSG product, an energy recovery heat exchanger that recovers heat from a hot gas stream, will initially serve organizations with gas turbines up to 100MW. By implementing the HRSG system, ATCO says companies will be able to create cost savings through recovered waste heat or renewable energy sources.
February 5, 2013 - Viessmann says it has added several economical options to its line of indirect-fired domestic hot water (DHW) storage tanks with Vitocell 100-VH/BH series. Single-coil (Vitocell 100-VH) and dual-coil (Vitocell 100-BH) tanks are available in 79 and 119 USG (300 L and 450 L) sizes. All Vitocell 100-VH/BH models feature a large heat exchanger coil reaching to the cylinder floor “to maximize energy transfer”, utilize full tank capacity and promise fast recovery rates. The 100-BH tank includes a second coil to allow the integration of a solar thermal system and heating boiler for shared DHW production (solar heat is transferred through the lower coil, while the boiler provides supplementary heating through the upper coil). An optional 220V electric heating element adds further DHW heating flexibility to Vitocell 100-VH/BH tanks, eliminating boiler run-time in the summer, says Viessmann, or providing a permanent auxiliary heat source when solar heating is in short supply. Two inches of CFC-free foam insulation and a fitted nylon insulation jacket minimize standby losses and help contribute to operating cost savings of up to 50%, says the company, when compared to conventional direct-fired tanks. The tanks are available through Viessmann wholesale partners across Canada (excluding British Columbia and The Yukon).
