RAYMAX

1525 —
Unique Design Allows
Quick Removal and
Replacement of
the Element and
Reflectors

Watlow's RAYMAX®1525 is a rugged radiant heater with a
unique design that allows quick removal and replacement of
the element and reflectors. Instead of dismantling the heater,
the parts are simply removed from the front. Replacing dirty
reflectors often can improve heating efficiency by up to
30 percent.

The RAYMAX 1525 is available with either a fast responding
quartz element or an Incoloy
tubular element. Both are supported by stainless steel
hardware in an extruded aluminum housing.

All stock units come with 1
mounting bolts that slide along the heater's length to
accommodate mounting considerations.

Power Leads

Appropriate power leads come attached to the heating
element(s).

airpin Element

H

A WATROD hairpin-shaped tubular element provides the
convenience of single end wiring and a reduced no-heat area
on the non-terminal end.

Liquid Tight Housing

On this style, the hairpin element terminates in a liquid tight

ousing to permit operating in a hose-down area or exposure

h
to weather. The cast aluminum housing has a
conduit fitting. The box is 2

including conduit hub.

Element Styles

Single and Dual Elements

Straight length WATROD round tubular elements come in
single or dual styles. The dual style produces twice the
wattage of the same length single element. Dual elements can
also be jumpered to per
twice the rated voltage up to 480V

mit single end wiring and operating at

Å(ac).

Quartz Tube Element

Watlow quartz elements provide the advantage of faster heat-up
and cool-down—important when encountering frequent line
stoppages. A standard

1

⁄2 inch (13 mm) diameter quartz tube

provides strength and long resistance wire life.
