This unit was designed to introduce 45,000 CFM of fresh air for both very cold winter days, with 3 stages of steam heating, or mild summer days, with the electric heater when the steam plant is shut down.

Frost control in the steam coil is provided with 3 installed coils in series. The 2 first stages are on/off and the last stage will modulate its capacity to maintain the desired supply temperature.

Heating is 5,103MBH at 150 psig steam pressure and 500KW electric heater. Steam piping was done at our factory to include modulating, manual and automatic valves.

Filtration is done with MERV 8 (2’’) in a face-loading filter bank built above a 3-sloped drain pan with catwalk.
