Class-Leading Energy Efficiency and Better Ventilation Are Of Key Interest to Building Owners

Ultra High Efficiency SA-Series

Cambridge Ultra High Efficiency SA-Series

The SA-Series provides the commercial and industrial marketplace with an affordable way to retrofit current systems as existing unit heaters fail and need replacement.

Designed with the needs of building owners and tenants in mind, Cambridge Engineering has introduced a new line of Blow-Thru® Direct Gas-Fired Space Heaters built to efficiently and safely heat small commercial and industrial facilities.

The new line of space heaters, called 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. The S-Series is documented to achieve 30-70% energy savings over other unit heaters or traditional boiler applications. Computer modeling shows the SA-Series will achieve similar savings, providing a quick payback on equipment and installation costs. The units are prequalified for EPAct Tax Credits, and may qualify for additional energy rebates through local utility providers.

“We are excited about the response from early adopters who have used SA units to replace or upgrade current unit heaters,” said Marc Braun, EVP for Cambridge Engineering. “These decision makers love the SA250 because of the flexibility and energy savings offered. The SA-Series provides the commercial and industrial marketplace with an affordable way to retrofit current systems as existing unit heaters fail and need replacement.”

The apparent simplicity of the SA-Series heater hides the fact that it incorporates several patented and proprietary technologies, to provide legendary Cambridge dependability and ease-of-use.                                                                                        

The SA-Series was designed for efficiency, dependability, safety, and ease of use. It offers 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 warranted for five full years (the longest warranty in the industry), with all other components warranted for two years.    For more information about the new SA-Series, please visit
