Cambridge Engineering was recognized for excellence in product engineering by The Air Conditioning, Heating & Refrigeration NEWS magazine, earning a Silver Award Cambridge’s SA 250 HTHV Direct Fired Heater is a commercial and industrial direct-fired heater that provides heating, ventilation, and destratification – all from one unit. The Silver Award winner is a 92%-efficient, 100% outside air, direct-fired heater that is an energy-efficient way to heat and ventilate a building with high bay ceilings. It allows HVAC contractors to provide customers an energy-efficient alternative to an energy-inefficient unit heater. The SA 250, through a U.S. Department of Energy (DOE) study, saves at least 20% on natural gas heating costs.
