Direct-Fired THP-4000
Direct-fired make-up air heaters work well in most types of construction applications, helping to control moisture and air contaminants. These heaters operate similar to a permanent air handler, providing evenly distributed, warm, dry air. Installed either inside or outside, THP-Series heaters draw 100% fresh air through the unit’s intake and discharge tempered air controlled by a remote thermostat.
