Cambridge Air Solutions SA-Series


Perfect for spaces with lower BTU requirements

All employees should have the opportunity to operate in comfortable working environments, even if they work in a high-bay facility or a warehouse with frequently-opened dock doors.  

Our SA-Series high efficiency space heaters exhibit an innovative, compact design for commercial and industrial HVAC, offering the flexibility to be used for various building types and applications. It is a highly efficient direct replacement for unit heaters that doesn't have all the complexity of a condensing system. 

When properly applied, our heaters will heat the least amount of fresh air required to address the facility's air infiltration, make-up air and space heating needs. Computer energy modeling has found that Cambridge SA-Series space heaters are 20% to 70% more energy-efficient than all other types of indirect and direct gas-fired systems used to heat and/or ventilate commercial and industrial buildings.

The SA-Series can be installed in new construction projects, as part of a plant expansion, a renovation as part of an HVAC upgrade or a retrofit of an existing building.

High Temperature Heating & Ventilation (HTHV) is a technology class of products established by the Department of Energy with the goal of increasing the energy efficiency of heating equipment throughout the US.  By definition, HTHV technologies are certified to a discharge temperature which is greater than or equal to 150°F and a temperature rise greater than or equal to 140°F and also has the ability to both heat and ventilate commercial and industrial structures.  These energy-saving products provide more than just heating. They also provide Heating, Ventilation, and Temperature Destratification from the same piece of equipment.

HTHV products are among the safest gas-fired space heaters on the market and Cambridge’s HTHV products also have the lowest total cost of Ownership when compared to other heating technologies, especially when compared to standard efficiency unit heaters. Our HTHV products have been proven through a DOE study to save between 20% to 70% on energy depending on the building, location, application, and installation.
