Type DH duct heaters are pre-engineered,
factory assembled units consisting of a
standard frame section, heating elements and
a prewired control panel. They are available
in a wide range of standard frame sizes, with
various heating capacities and heating stages
operating on AC voltage ratings of 120 to
600V.
The standard duct heater is designed to be
inserted in a rectangular opening cut in the
side of a horizontal or vertical duct. For larger
ducts or where it may be more desirable to
attach the duct directly to the heater, a frame
may be added to the heater.
