Design
Heating low viscosity oil —
For better flow, improved
characteristics, and maintenance of
bulk oil at predetermined
temperature levels. Also suitable for
hydrocarbon based coolants and
heat transfer oils where adequate
flow conditions are maintained.
Features rugged construction —
Sturdy heating steel screw plugs
provide superior rigidity and
strength. Heavy duty jumper straps
and terminal posts assure
permanent tightness of connection’s
carrying capacity.

High conductivity elements —
Filled with highest purity blends of
magnesium oxide refractory (MgO)
compacted to a rock hard density to
insure maximum thermal conductivity,
maximum electrical resistance, and
assure long element life.
Heavy coil construction —
Watt density on the heating coil is
designed for low watt density
operation by increasing the coil
diameter and length to give
maximum coil surface area and limit
coil surface temperature, providing
Note: The integral thermostat functions as a
temperature control only. This is not a fail
safe device. An approved pressure and/or
temperature control should be used with
these heaters to assure safe operation. See
the Temperature Section for our selection of
control devices.
