Equipment Specs

THP-Series

THP-Series 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.

CH-Series

The CH-Series construction heaters are designed for portability and versatility with high discharge temperatures and comparatively lower fan induction ratios. These direct-fired heaters work well in loose enclosures such as under concrete deck pours, masonry enclosures, and spot heat situations. This series is ideal for sites where only 115V power is available.
