Watlow Electric RAYMAX 1525 - Manual (Page 2)

Hairpin Element
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
housing to permit operating in a hose-down area or exposure
to weather. The cast aluminum housing has a
1 ⁄
2
inch NPT
conduit fitting. The box is 2 13 ⁄
16
inches x 3 3 ⁄
8
inches x 5 1 ⁄
4
inches
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 ⁄
2
inch (13 mm) diameter quartz tube
provides strength and long resistance wire life.
