AFX AEROFLO FEATURES

The floating, heavy gauge,stainless steel combustion chamber is designed to withstand contraction and expansion cycles to ensure long, trouble-free operation.The original Counterflo combustion chamber was introduced over forty years ago.This time-tested reliability and proven performance assures the extended life of the Aeroflo chamber.

In the AFX Series Aeroflo heater design, the combustion products flow internally four times across the path of the air to be heated. The first two passes are within the primary heat exchanger, a stainless steel combustion chamber where the flame and hot gases release 75% of their total heat through contact with the entire chamber surface. The third and fourth passes are made in the secondary heat exchanger through two staggered economizer tube sections. The net result is a compact and highly efficient heat exchange unit.

AIR COOLED RADIATION SHIELD

An internal, air cooled radiation shield is provided to ensure minimum radiation and transmission losses, less than 2%, and cool cabinet surfaces.

Integral tubular steel structural members provide maximum cabinet rigidity. Reinforced steel surfaces are cleaned and painted with heat and corrosion resistant industrial enamel.

The combustion gas exhaust system includes a heavy-duty exhaust fan, three phase motor, V-belt, or direct drive and heat slinger to yield low ambient temperature motor operating conditions.

Heavy-duty, turbine-bladed propeller fans provide high air flow at low velocity for minimum fan horsepower and quiet operation. All fans are tested in accordance with AMCA standards and driven by V-belts safely enclosed within the air intake section.
