Consulting-Specifying Engineer - April 2008 - (Page 68) New Products Low-torque actuators Consider Siemens Building Technologies’ OpenAir GQD Series as an energy-efficient actuator. Suitable for commercial dampers, economizer equipment, and VAV installations, these low-torque actuators will return to the fail-safe position upon power failure to protect equipment. The device is designed as a direct-coupled, spring-return electronic actuator for modulating, two position, or floating control of building HVAC dampers. The units are pre-cabled, plenum-rated, and offer a run time under 30 sec. Running from either AC or DC power, GQD Series actuators operate with a DC backup power supply. www.usa.siemens.com/ buildingtechnologies » INPUT RS# AT WWW.CSEMAG.COM/QUICKRESPONSE » » E-MAIL PRODUCT NEWS TO CSEPRODUCTS@REEDBUSINESS.COM » » » » » » » » » » » » » » » » LIghting fixture Illuminate large indoor or outdoor spaces, such as airports, sporting facilities, natatoriums, atriums, and other multi-story environments with the Ametrix XL Extra Large asymmetric fixture series from Cooper Lighting.
