The PDP model series expands on the size range of the HD/HDB model series providing product that is certified for commercial and industrial applications in sizes from 150 through 400MBH.

The Greenhouse Power Vented Unit Heaters are perfect for horticultural, commercial, industrial and agricultural uses.

Designed to utilize the smallest-diameter vent pipe possible.
PDP models are designed to operate against 0.5 inches of external static pressure.
"Wing" screws so that the bottom pan can be dropped without a screwdriver or nut driver.
A level hanging mechanism for easy field adjustments after adding accessories that may change the unit’s center of gravity.
