Modine Separated Combustion Heaters

Separated Unit Heaters are recommended when working in environments with a harsh atmosphere. For example, rooms with chemicals, high humidity, or negative pressure. These units pull the combustion air from outside the heated area, either from outside air or an adjacent room. This process prevents the risk of using toxic indoor air for combustion. If you do not have harsh chemicals in your heating room, check our selection of standard shop and garage heaters.
