Overview

SolutionAir AW-D units use ultra-efficient direct-fired burners allowing better control over discharge temperature. This method eliminates the use of a heat exchanger by burning the combustible directly in the airstream, achieving 100% combustion efficiency and a 92% overall thermal efficiency (8% of the total heat goes into the latent heat of water formed by combustion).
AW-Ds can provide a fully modulating 30:1 turn down ratio. Providing this high of turndown and a fully modulating system, the unit will provide precise temperature control to the space which results in the highest quality IAQ and comfort. This smooth operation also maximizes the life of the equipment in lieu of constantly staging valves and stopping and starting fans.

In the USA, our direct fired equipment can be 100% outdoor air or use a mixing box to allow up to 80% recirculated air for better energy savings in certain applications. In Canada, direct fired equipment must be 100% outdoor air, and mixing boxes are not allowed.
