INDUSTRIAL AIR MAKE-UP UNITS
HOW IT WORKS
Air make-up units replace contaminated air exhausted from industrial and commercial buildings or spray booths, with heated outdoor air. AMUs maintain a constant leaving-air temperature regardless of the incoming, outdoor air temperature. Air make-up units replenish equal amounts of fresh air for every cubic foot of air exhausted.
A direct-fired burner with a turndown ratio of 30:1 is 100 percent efficient — all the heat goes directly into the airstream. The high turndown capability allows the flame to adjust to outdoor air temperature swings throughout heating season. For example, a unit with a maximum temperature rise of 90 degrees in the winter can adjust down to as little as a 3 degree temperature rise for milder spring and fall weather.
GFS AMUs use structural G90 galvanized steel for the base and tube frame, along with heavy-duty G90 steel casing. Additional construction features include:
|Interlocked wall seam and roof panels|
|Hinged service doors with flush-mount latches|
|Casing insulation with G90 galvanized steel liners|
|Multiple mounting arrangements:
