Hydronic Heating
Increased Air Throw Capacity
The Air Flow Induction Optimizer increases the throw for Reznor Models WS.
This increased ow results in energy savings and better environmental control.
The unique shape of the deecting louvers which create layers of hot air at the
unit outlet. The space created between layers causes air around the front of the
unit to be drawn into the air stream and mixed with the heated air. The result is
a signicant increase in the air throw.
