Applications

Molds and other heat-transferring metal parts
and air heating applications. Immersion heat­ing with flange, screwplug, threaded fitting or
other means of mounting.

Advantages

Elements with both terminals at one end, in
dies, can simplify wiring in many cases. Use
slim elements to concentrate heat into a con­fined area, taking up less space than a
U-shaped element with terminals at each end.

Features

Construction — Similar to the standard
Chromalox tubular design, except that both
terminals of the embedded resistor wire are
at one end of the element. 10" lead wires have
silicone-impregnated Fiberglas
are attached to the terminals inside a ceramic
terminal bushing.

Sealed End for Immersion Heating on end
opposite terminals is provided on all stock,
single-end elements. When ordering non­stock elements for use as immersion heaters,
specify “sealed end”.

Work Temperatures — See Tubular Heater
Overview section.

Bending — Generally not recommended
for single-end elements.
