Cambridge Engineering Announces New Ultra High Efficiency Space Heater

An Addition to the SA-Series, the SA350 is Designed to Deliver Energy Efficiency to Medium-Sized Commercial and Industrial Applications

ST. LOUIS – Expanding its new line of SA-Series space heaters, Cambridge Engineering has added the SA350, capable of delivering 350 MBH (350,000 BTUs per hour) for commercial and industrial applications.

Introduced in 2013, the Cambridge SA-Series uses the same proven technology as the larger ultra high efficiency Cambridge S-Series, but is sized for efficient heating and ventilation of smaller spaces. Randy Niederer, Director of Marketing for Cambridge, noted, "the addition of the SA350 allows for greater end-user flexibility in an 'off-the-shelf' heater for spaces larger than the SA250 serves, but smaller than those served by our S-Series."

Designed to deliver the highest energy efficiency available on the market, Cambridge Engineering's patented Blow-Thru® Direct Gas-Fired SpaceHeaters are built to efficiently and safely heat commercial and industrial facilities. The flagship S-Series is documented to achieve 40-70% energy savings over other unit heaters or traditional boiler applications. In their first year on the market, SA-Series units have achieved similar savings, providing a quick payback on equipment and installation costs. The SA-Series unit's optional year-round ventilation capability allows it to cycle between providing 100% fresh, outside air and ultra-high efficiency heat for additional seasonal savings.

"We call the SA-Series the Unit Heater Beater™," adds Niederer, "because it overcomes the stratification and energy- wasting issues associated with traditional unit heaters.  The new SA350 demonstrates Cambridge Engineering's commitment to provide customers with the most energy-efficient heaters available on the market."  The SA-Series space heaters have already made inroads into broad applications including aircraft hangars, auto service areas, greenhouses, farm buildings and garages, fire stations, loading docks, manufacturing and maintenance areas, retail stores, small warehouses, and sporting facilities.

The apparent simplicity of the SA-Series heaters hides the fact that they incorporate several patented and proprietary technologies, to provide legendary Cambridge dependability.   The SA-Series units are designed for efficiency, dependability, safety, adaptability in installation, and, ease of use.  They offer the flexibility of being mounted thru-wall, under roof, or on rooftop, potentially providing more useable interior space. As with other Cambridge heaters, the stainless steel burners are supported with the longest warranty in the industry (five full years), with all other components warranted for two years.
