Cambridge Product Line

When it comes to determining they types of Cambridge Engineering units that you would need to heat and ventilate your facility the answer is not always easy. You might have a small building with just basic heating needs. Or you might have a large facility that has mechanical exhaust and you need equipment that provides both exhaust replenishment and heating. Either way, knowing which products you need to provide the best indoor air quality for your facility is not always cut and dry.

M-Series makeup air units (MUAs) by Cambridge are on the cutting edge of Makeup Air technology and boast many unique features other Makeup Air Heaters on the market cannot duplicate. Makeup air is designed to “make up” air in your interior space when you have exhausted all that is available. This type of HVAC solution pulls in fresh, tempered air from outside your building to replace existing air that cannot be recirculated.



Cambridge HTHV Space Heating Systems are designed to meet a building's heat and air load requirements. Our unique blow-thru design, with 160°F maximum temperature rise and discharge temperature, delivers more usable heat and thermal comfort with minimal temperature variation throughout the heated space. This commercial space heater is 40% to 70% more energy efficient than all other types of indirect and direct gas-fired systems used to heat large commercial and industrial buildings.


SA-Series High Efficiency Space Heaters exhibit an innovative, compact design for commercial HVAC, offering flexibility to be used for various building types and applications. It is a highly efficient direct replacement for standard and condensing unit heaters without the complexity of a condensing system.  When properly applied, our highly efficient space heaters will heat the least amount of fresh air required to address the facility's air infiltration and space heating needs.
