Semco Dedicated Outside Air Units

Available in Eastern Michigan, Michigan U.P.

Economically provides high quantities of outdoor air while simultaneously controlling indoor humidity levels. SEMCO accomplishes this by dehumidifying the supply air to very low dew points in an energy-efficient manner, without the use of a regeneration heating source. Outdoor air is continuously delivered to the occupied space while simultaneously controlling humidity levels at the conditions recommended by ASHRAE, even at part-load conditions.
