ELECTRIC HEAT TRACING:
Electric heat tracing is a system used to maintain the temperature of pipes and vessels. Trace heating takes the form of an
electrical heating element run in physical contact along the length of a pipe. The pipe must then be covered with thermal
insulation to retain heat losses from the pipe. Heat generated by the element then maintains the temperature of the pipe. Trace
heating may be used to protect pipes from freezing, to maintain a constant flow temperature in hot water systems, or to maintain
process temperatures for piping that must transport substances that solidify at ambient temperatures. Electric trace heating
cables are an alternative to steam trace heating where steam is not available or unwanted.
Hot water service piping can also be traced, so that a circulating system is not needed to provide hot water at outlets. The
combination of trace heating and the correct thermal insulation for the operating ambient temperature maintains a thermal
balance where the heat output from the trace heating matches the heat loss from the pipe.
A similar principle can be applied to process piping carrying fluids which may congeal at low temperatures, for example, Furnace
oil, HFO, edible oils, tars or molten sulphur. Trace heating element scan prevent blockage of pipes.

HOPPER HEATER (TUBULAR / JACKET)
For Hoppers, process vessels, storage tanks, lube drums etc.
We supply both tubular type and jacket type hopper heaters. Jacket
type hopper heater are having more life as it provides uniform heating
in hoppers, vessels etc. WhereasTubular hopper heaters are placed in
a aluminium box which makes it easy to replace without removing
insulation above it. So both are having their own advantages. Hence
we supply both types of hopper heaters.
CONSTRUCTION
Heating jackets comprise of flexible heating elements, distributed very uniformly on to a
fibreglass or quartz cloth carrier. The fibreglass or quartz cloth carrier is tailored to the shape
of the vessel to be heated. Eye-lets and laces provided on the panels, ensure a snug fit of
heater on the surface being heated, avoiding any air gaps. The heating elements terminate
on cold leads, which are connected to the power supply. The otherside of the heating jacket is
provided with insulation to avoid the heat losses and covered with Teflon coated fibreglass or
silicon coated fibreglass cloth to make it waterproof and suitable for outdoor applications.
FEATURES
Uniform heating Every close insulated distributed heating element ensures effective and uniform heating.
Highly Efficient Heat is applied on the surface from where heat loss occurs resulting in minimal heat loss.
Easy Maintenance Being external heating system maintenance is possible without the need for costly disturbing
shutdowns.
Precise Temperature Thermostatic controls associated with heaters enable very precise temperature control with
Control minimal thermal lag.
The high flexibility of the carrier material enables the heaters to fit snug on complicated shapes

FLEXIBLE HEATING TAPES
These are highly flexible in nature and are ideal for heating columns, pipes, valves and transfer lines particularly when these
applications required to be observed. These heating tapes can be applied to metal pipes as well as glassware.

The wattages are maximum wattages at 230V 1ph.AC. Other wattages and voltage is optional.
Heating tapes are made with nichrome wire element wound on a fibre glass core, then braided 2 times and lapped 2 times with
fibreglass yarn. This element is sandwiched between two layers of fibreglass cloth with the cold leads at one end for
connecting to supply point. These heating tapes can withstand up to 400°C and for 800°C application, quartz yarn and cloth
will be used instead of fibreglass.
These heating tapes are available in different lengths from 1 mtr to 10 mt length with maximum 250 watts per Mtr.

Immersion Heaters
Use in tank heating, usually for stagnant liquid to heat up and maintain at certain desire temperature. Multiple heaters are used
for a bigger tank dimension where heat distribution can be spread more widely. Temperature control by means of ON/OFF
thermostat or contractor is adequate where precise control is not required.
Industrial immersion heaters are designed for direct contact heating of water, oils, viscous materials, solvents, process
solutions and gases for many industrial heat applications. Since all heat is generated within the liquid or process, virtually
100% energy efficiency is achieved. Design temp varies according to material grade i.e SS321, INC 800, SS304, INCONEL,
