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.

Heater Frame — Galvanized for corrosion protection.

Heating Elements — 80/20 Nickel/Chromium open coil or painted steel finned.

Mounting — Insert or flanged designs configured for horizontal airflow.

Control Panel — Integral control panel prewired for easy wiring and installation.

Listed for zero clearance to combustible materials.

Overtemperature Protection — provided with both manual and automatic resets.

Factory Prewired — 48 Amp maximum circuits to meet NEC requirements.

Controls — 24V transformer, magnetic contactors, airflow switch, disconnect switch and overtemperature cutouts allow for thermostat control.

Fusing — Power fusing on heaters above 48 amps.

Easy Wiring access through opening in terminal box.
