Rugged Construction Elements — Sturdy 0.475"
diameter INCOLOY® sheath tubular elements are
mounted to a heavy 1/4 or 3/8" thick steel flange.
Element fasteners allow for easy replacement.

Corrosion-Resistant Terminal Enclosure —The
element terminal enclosure is made of 16 gauge
high-temperature, corrosion-resistant steel and
includes 1" thick high-temperature insulation to
minimize temperatures in the wiring area.

Wiring Box — The 16 gauge wiring box encloses
individual terminal blocks for each circuit. Threaded
stud type terminals are provided to permit quick
positive attachment of circuit wiring conductors.

All Heaters can be mounted in any position; top, side
or bottom entry. In high ambient temperature opera­tions, least corrosive action and least oxidation to
the terminals will occur if heaters are mounted with
terminals in the coolest possible ambient, usually on
bottom or side of duct. Minimum duct size is A or L

dimension plus 3/8" and B dimension plus 1-5/8"

Application & Selection Guidelines

Maximum Work Temperatures —Type ADH heat-
ers can generally be used at the following maximum
temperatures, provided the minimum air velocity is
maintained uniformly through the heater.

Air Velocity

(Ft./Sec.) Max. Outlet Air Temp. (°F)

4 - 36 800

Note — Maximum temperatures are based on 30

2

W/In

. If elements have a lower watt density, work
temperature may be increased; if watt density is
higher, work temperature should be lower.

Note — An airflow type switch or other device is

recommended to protect against loss of airflow.

Note — See Allowable Watt Density & Heater Selec-

tion Graphs in the Technical section of this catalog.
