January 22, 2014 - Jaga’s new Freedom radiator boasts a compact, contemporary design and efficiency comparable to units twice its size. Designed for small and sustainably constructed spaces, the unit received its name from its “extensive flexibility” and ability to be “integrated into any climate control dynamic”. Also suitable for condensing and non-condensing cooling, all Freedom radiators are fitted with a condensation drain.
January 13, 2014 - Leviton has introduced its new humidity sensor and fan control device, featuring digital sensing technology to help control ventilation in humid or damp areas in the home. It offers single pole for control of a ventilation fan or fan/light combination and is compatible with incandescent, LED, CFL and fluorescent lighting loads and ventilation fans up to 1/6 HP. According to the company, regular use of the device reduces energy usage by automatically operating the fan only when needed and minimizing unnecessary and continuous use.
December 18, 2013 - Lennox Industries says it will expand its portfolio in 2014 to offer the North American commercial HVAC market variable refrigerant flow (VRF) technology.
December 17, 2013 - Schneider Electric’s Powerbus 400A/600V busway claims to replace traditional centralized cable distribution runs with a more flexible method of power distribution above data centre equipment, enabling energy monitoring, reduced energy losses, and improved flexibility for equipment moves, adds and changes in the facility. The incoming power feed units offer isolated metering compartments, improved cable entry and new metering voltage options, while the plug-in units offer Powerlogic power metering options to simplify monitoring of energy usage at row level and the rack and branch circuit levels, says the company. The product boasts the highest plug-in unit density on the market, with up to 20 openings every 10 ft, and is listed to UL 857 for Safety for Busways. WATCH the video below.
November 21, 2013 - Schneider Electric has launched the Altivar 212 mobile programming application and drive to iPad converter cable, which allow users to perform all Altivar 212 and S-Flex drives programming through Apple iPads. The app enables an iPad to function as a drive keypad for set up using pre-loaded common default parameters for HVAC fan and pump applications, significantly streamlining the configuration process, says Schneider. Entire job close-out files can be loaded on an iPad and presented to a building owner for retention. Motor data for each fan or pump is also stored inside the app should it be required to reset the drive to the original settings loaded by the service technician during building commissioning.
October 26, 2013 - Schneider Electric unveiled an HVAC/R machine retrofit solution—Condenser Fan Pak—designed to improve both new and existing air-conditioning and refrigeration equipment.
August 26, 2013 - The CCLP low voltage relay panel from Cristal Controls is now BTL certified, promising full compatibility with most Building Management Systems (BMS) that use BACnet technology. The relay panel series can be supplied in a custom form or with seven standard models. “We are pleased to be one of the only option for relay panels with BTL certification and that means any of the big integrators in the market are now able to work with our systems without having to worry about compatibility issues” said Pierre Chaput, company president and founder.
August 26, 2013 - Johnson Controls has added ductless mini-split air conditioners and heat pumps to its York Affinity series and LX series product lines to provide more heating and cooling options to homeowners and commercial building operators.These units deliver cooling or heating to structures without installing air handlers and ductwork, and can be used to condition computer-server rooms where temperatures must be maintained. The systems combine smaller outdoor units with wall-mounted indoor units, linked by a conduit requiring a 3-in. to 4-in. opening. Single-zone mini-splits provide individualized temperature settings in a single room, while multi-zone models connect a single outdoor unit to as many as five indoor units.
July 30, 2013 - GE Energy says its ecomagination-qualified eBoost software provides data centres and IT organizations a way to reduce energy consumption and cost without sacrificing reliability, boasting increased efficiency of about 92-99% for GE’s 225-750 kVA SG series uninterrupted power supply (UPS) modules. eBoost software continuously monitors utility power quality and activates double conversion mode only when utility power quality falls outside of data centre power quality requirements, reducing the amount of time spent in a less efficient traditional “double conversion” mode, says GE. According to the company, the software also increases reliability and redundancy by enabling up to six UPS modules in parallel operation and by eliminating single points of failure.
July 24, 2013 - The new iPhone, Android and BlackBerry mobile application from ecobee allows customers to monitor and control ecobee EMS and EMS Si wireless thermostats in multiple locations. According to the company, app users can be more responsive to their tenants, employees and customers, identify and address heating and cooling problems quickly, decrease the number of unnecessary and expensive on-site service calls, and increase overall energy efficiency. With the ecobee EMS App, customers can create a custom Watch List of thermostats to keep tabs on priority spaces and locations with repeat issues, while enabling users to adjust the temperature on the thermostats remotely, based on occupancy levels.
July 3, 2013 - Available through Nirvana Chauffe-Piscine, the Silensor pump and the Nirvana pool heater claim to maximize swimming comfort while significantly reducing energy consumption and the resulting electricity bill. The Silensor pump heats the swimming pool water by recovering and distributing the heat it produces. According to the company, the pool heater will reach the desired temperature in a shorter amount of time, as the heat generated by the pump will be transmitted directly to the pool water rather than remaining inactive and unproductive in the ambient air. Annual savings are estimated at more than 35%.
June 26, 2013 - StacoVAR mini by Staco Energy Products is an automatic power factor correction bank, including a microprocessor-based controller, which automatically adjusts to system load. StacoVAR mini extended kvar range was designed for industrial and commercial environments which rely on inherently inefficient motors for air conditioning/heating and air movement, pumps, manufacturing or warehousing equipment and more. These motors typically produce poor power factor, which can manifest itself in higher utility bills due to penalties and surcharges for poor power factor, says the company. Models are available from 11.5 kvar to 28 kvar at 208V, 15 kvar to 37.5 kvar at 240V, and 28 kvar to 75 kvar at 480V.
June 17, 2013 - GE says its new TLE series Uninterruptible Power Supply (UPS) with three-level converter technology provides mission-critical facilities with reliable power, while achieving up to 96.5% efficiency. According to GE, the TLE series features an ultra-high efficiency in double-conversion mode which provides significant life cycle cost savings for the data centre industry. For a typical enterprise-class data centre with a 6MW load, the TLE series UPS has the ability to reduce annual energy consumption by more than 2 million kWh, predicts the company.
