Heating of viscous materials, in large storage
tanks, to pumping temperatures. Maintaining
an entire tank of viscous fluids such as fuel
oil or asphalt at pumping temperatures is very
costly. In many applications it is not practical
or economical because the tanks are located
underground or are not insulated.
Type SHO Suction Oil Heaters are a cost effective
solution to this problem. Suction
heaters are specifically designed to heat only
that amount of material that is to be pumped
from a large storage tank. The outlet nozzle
is attached to the pump suction. The heater
heats the material inside the heater pipe body
which is then drawn through the heater into
the suction side of the pump. This technique
saves substantial energy costs since it is not
necessary to heat the entire contents of the
tank to draw off relatively small amounts of
Complete weather-proof construction makes
these heaters perfect for installation in large
outdoor storage tanks. Large heater inlet provides
smooth, full-flow through the heater.
Terminal Enclosure — SHO circulation heaters are designed to be installed outdoors in
exposed areas. Enclosures are designed to be
Moisture Resistant or Moisture and Explosion
Low Watt Density Elements make the
heaters safe to use on most viscous liquids.
Carbonization is minimized.
Vessel — Pipe body and nozzles are galvanized ASTM A53B carbon steel pipe. Heater
and mounting flanges are ANSI B16.5 150 Lb
galvanized carbon steel. Assembly provided
with thermal insulation and painted sheet
Thermostats and High Limit Controls— SHO
suction heaters should be provided with
temperature controls to control fluid outlet
temperatures and limit internal temperatures
under abnormal or no-flow conditions.
Depending on customer specifications, SHO
heaters may be supplied with factory equipped
AR thermostats, high limit cutouts or other
Control Panels — Integral or remote mounted
control panels with electronic controls and
solid state (SCR) or contactor power controllers
can be provided using virtually any
combination of control devices. Consult the
Controls section for details.
