CIRCULATION HEATER
Maltec Circulation
Heaters are
made with stainless steel because of its anti-corrosive qualities. The
application involve using a pump that flows the liquid through a
closed pipe circuit (IE. water or glycol solution) that is reheated. A
major consideration for this application is viscosity. Heat that is generated
by the electric heater allows the liquid to be viscous enough to pass through
the circuit of pipes. Circulation heaters come in a range of watt densities
that are specifically designed for the medium that is heated. The required
wattage to heat the oil or water is highly correlated to the flow
rate (in GPM). The oil or water enters through an inlet (the inlet closest
to the flange heater) and gets heat applied to it as it flows within
a vessel chamber and exits the outlet nozzle (or flange) where it
circulates throughout the piping circuit. Insulation is often required for
vessels in order to preserve the heat to be applied within the vessel.
Efficient heat application can often reduce unnecessary costs through heat
loss. Thermocouple
probes or RTDs, can
be used with the electric heaters to maintain the oil or
water at the preferred temperature.
Other useful features found with electric circulation heaters are drain valves. They can be installed in any location on the vessel and allow for easy maintenance of the heater. The water or oil can be purged through the drain valve allowing for maintenance on the elements. Calcium deposits and other residue can be found on elements and should be cleaned several times a month. Circulation heaters also come with the choice of horizontal or vertical mounting depending on your application.
Maltec Circulation Heaters are also available in moisture resistant terminal boxes for hazardous environments and it is an exceptional choice for heating process liquids, non-corrosive to the materials of construction.
Oil and Gas
companies have specifically used circulation heaters to
assist them in the process of modifying viscosity levels of their heating oils.
Crude oil enters an inlet of the vessel at a cool temperature and exits the
outlet at a temperature more convenient for flow as it travels from one end of
the transport pipe to the other. Hydraulic fluid can also be heated using this
electric heater for heat transfer purposes, and to resist cooler climates.
Immersion heaters are widely used in a variety of industries particularly the oil
and pipeline sector for several different purposes. These industrial heaters
are specifically designed so that oil, water, viscous materials, gases,
solvents and other different process mixtures can be heated in direct contact
with each other. This allows the heat to be generated within a single enclosure
or solution and optimum efficiency can be achieved.
