Howden American Fan Company has introduced its new ventilation concept for underground parking garages, which includes two alternative options — the Jet Thrust Fan and the Induction Thrust Fan. The company says the new system lowers the required parking garage height by about 4 ft, reducing excavation and cement costs and lowering overall construction costs.
Automated Logic Corporation has made enhancements to its flagship product, the WebCTRL® building automation system. The web-based building automation platform now features optimized trend reporting, new visualization tools, mobile support capability, and Open Automated Demand Response (ADR) to further help manage building energy conservation measures, identify key operational problems, and analyze the end results.
Marley Engineered Products introduced its Artisan SmartSeries® Architectural Digital Wall Heater. The new wall heater automatically adjusts wattage output and blower speed resulting in quiet operation and energy efficiencies. The unit features 5 day/2 day programmability with four daily program periods to respond to a variety of environment needs.
SPX Cooling Technologies has announced additions to the Cube™ Evaporative Condenser product line. An ideal option for industrial refrigeration applications that require safe design, installation, and operation with ammonia and other refrigerants, Cube Evaporative Condensers are available in both forced draft/blow through (BTC) and induced draft/draw through (DTC) models. New DTC models are now available in 8.5-ft nominal widths.
The Sensaphone® Airflow Sensor measures the rate of airflow and alerts data center managers when conditions fall outside the ideal range. The sensor monitors the presence or absence of cool moving air and provides relative airflow as a percentage from 0 to 100.
Webster Combustion Technology LLC has introduced the model JBE(X).
