Cambridge Engineering Launches New App for Building Owners & Specifying Engineers

Online TruBTU® calculator provides comparison of direct-fired technologies

ST. LOUIS – Cambridge Engineering, the leading manufacturer of high temperature heating and ventilation (HTHV) direct-fired gas products for commercial spaces, launched its new TruBTU® app at January’s International Air-Conditioning, Heating, Refrigerating Exposition (AHR Expo), held in Orlando, Florida. 

The TruBTU® app allows end-users and specifying engineers to compare and contrast the heating capability available from HTHV space heating products with less efficient conventional direct-fired technologies. “Engineers, owners and facility managers are faced with a myriad of decisions in heating and ventilating their properties,” notes Randy Niederer, director of marketing for Cambridge.  “This application helps them determine the best and most efficient means for doing both.”

TruBTU® features comparisons of blow thru, draw thru and recirculating systems with actual available heating output and usable heat under specific operating conditions.  Available at, the application also provides outputs of the results in PDF format for distributing the information.

Sized for the efficient heating and ventilation of commercial spaces, Cambridge Engineering’s direct-fired gas space heaters are documented to achieve 40-70% energy savings over other unit heaters or traditional boiler applications, and use 100% outside air for safe, efficient heating.  In addition to the significant energy savings these products provide, they also qualify for custom and prescriptive rebates from gas utility providers across the nation and may qualify for tax deductions under the EPAct recently extended by the President.

“We chose the AHR Expo to announce the launch of TruBTU® because this app is the perfect tool for engineers who specify commercial heating solutions,” added Niederer, “This forum, held in conjunction with the ASHRAE winter meetings, is a natural platform to announce the availability of an invaluable aid to this audience.  TruBTU® represents the latest effort by Cambridge to provide its clients and customers with the very best in energy efficient products, accessories and services."
