Application
OMEGA® Over-the-Side Immersion
heaters are specifically designed for
heating fluids in tanks. Depending on
the tank shape, size, accessibility and
working area inside the tank, choose a
round or L shaped heater.
Standard sheath materials are Incoloy®
800 and steel with all wetted parts made
with compatible alloys.
Construction
Tubular heating elements are welded
into a liquid-tight junction box. Power
leads for the elements travel up through
the riser pipe and are connected to a
terminal block in a NEMA 4 housing.
Unless otherwise specified, heaters
are wired for three-phase from the
factory but can easily be converted
to single-phase.
A thermowell for a 9.5 mm (³⁄₈") diameter
bulb is standard to accommodate an
optional thermostat. A thermostat can
be field installed to mounting lugs
located in the electrical enclosure.
102 mm (4") sludge legs keep the
elements off the bottom of the tank
and above any deposits that may
accumulate there.
