The Engineered Air DJX Series furnaces redefine heating for the commercial – industrial market place. Our complete line of indirect gas-fired heating products incorporates independent proportional control of combustion air and gas flow. This ability to maintain the proper ratio of combustion air to gas burned is called “linearization”.

With Linearization our DJX Series product maximizes heating efficiency and Energy Savings. DJ models meet or exceed the ASHRAE 90.1 2007 and ASHRAE 189.1 high performance building requirements for (non weatherized) steady state at high fire operation.

The DJX heat exchanger was engineered to operate at nominal 91% efficiency throughout its complete firing rate and with increased efficiency during part load conditions. The DJX Series exceeds standards and optimizes energy performance.
