In recent years, belt-driven blower coils have been the standard for ducted applications that require greater static pressures. However, they require frequent belt tightening, inspection, and replacement. To combat this, in tandem with rising energy costs, International Environmental Corporation (IEC) introduced its new Horizontal and Vertical (HDY/VDY) Direct Drive Blower Coil Series at AHR 2017. Accommodating a variety of applications, these models are equipped with a direct-drive EC motor, eliminating belt-drive slips and other concerns associated with belt-drive systems. The new line offers an alternative that is more reliable and efficient, resulting in increased energy savings, an extended motor life, easier installation and less maintenance.
The HDY/VDY Blower Coil Series, which ranges from 600 to 3,000 cfm, features larger blower wheels and a broader range of performance than conventional ceiling fan coil units. Utilized most often in healthcare, hospitality, education, retail and other commercial mixed-use facilities, the HDY/VDY has significant acoustical benefits, eliminating the mechanical drive noises which are evident in typical belt-drive products. It features a wide range of vertical and horizontal model sizes, chilled and hot water coils and electric heaters, and are designed to work with varying space requirements.
Telkonet, Inc., creator of the EcoSmart platform of intelligent room automation solutions supporting the emerging Internet of Things (IoT), introduced one of the first devices able to control newer variable refrigerant flow (VRF) HVAC systems, the EcoSmart VRF Controller, at the 2017 AHR Expo. The new Controller helps further optimize VRF, VRV and VRP HVAC systems to maximize energy efficiency. To further extend that efficiency, the EcoSmart VRF Controller can be integrated with new VRF, VRV and VRP systems to provide in-room control of heating and air-conditioning. It operates digitally, versus traditional relay, and is compatible with ZigBee® controls.
Danfoss has extended its line of fully-equipped condensing units designed for low-temperature and medium-temperature outdoor applications. This line of high-quality condensing units is manufactured in the United States.
Danfoss has extended its existing line of Optyma™ condensing units for the US market to include the new Optyma™ Slim.
Designed with contractors in mind, Optyma Slim is compact, easy to install, easy to service--and offers reliable performance.
