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 improveheating efficiency byup to
30 percent.
The RAYMAX 1525 is available with either a fast responding
quartz element or an Incoloy®-sheathed WATROD round
tubular element. Both are supported by stainless steel
hardware in an extruded aluminum housing.
All stock units come with 15⁄8inch long, 3⁄8inch-16 thread
mounting bolts that slide along the heater's length to
accommodate mounting considerations.

Hairpin Element
AWATROD 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
housing to permit operating in a hose-down area or exposure
to weather. The cast aluminum housing has a 1⁄2inch NPT
conduit fitting. The box is 213⁄16 inches x 33⁄8inches x 51⁄4inches
including conduit hub.
Quartz Tube Element
Watlow quartz elements provide the advantage of faster heat-up
and cool-down—important when encountering frequent line
stoppages. A standard 1⁄2inch (13 mm) diameter quartz tube
provides strength and long resistance wire life.
