MS Series

Indoor Indirect Fired Separated Combustion Make-Up Air

MS Series are designed to be installed in dusty, dirty and mildly corrosive environments or where local codes require outside air to be used for combustion.

Sterling MS Series separated combustion indoor make-up air systems are similar to the ME unit except a separated combustion type duct furnace is utilized. Separated combustion units are designed to be installed in dusty, dirty and mildly corrosive environments or where local codes require outside air to be used for combustion. Heating capacities range from 100 to 1,200 MBH with airflows from 900 to 14,800 CFM.
