RELIEVING] EQUIPMENTS & ACCESSORIES
A] POWER SOURCES TEMCON - TR:
Temcon Power sources are ruggedly built equipment
for Pre-heat and Post-heat treatment work of pipe
welds, vessels, tanks etc.
in Power plants, Refineries, Offshore/ Onshore projects.
Constructed in heavy gauges CRCA steel sheets (or
stainless steel sheet-
on special order ), they are provided with castors
for easy mobility. Temcon power sources are fitted
with transformers having
class H windings and designed for long and trouble
free service. Temcon Power Sources are rated for
50 kVA, 65 kVA, 80 Kva,
and 100 kVA to provide heating power at 60/65 Volts
and 80/85 Volts to feed flexible heating Pads and
heater elements. To give an example , a Temcon
50 kVA equipment can feed upto 18 heatings pads
of 2.7 KW at 60 Volts or 15 elements of 3.25
KW at 65 Volts.

B] TEMCON MAINS CONTROL PANELS:
Temcon Mains Control Panels are made in variety
of designs and specifications. They can supply
power to heater pads, finger elements at 230Volts.
Due to their very high output power, they are
most suited for heat treatment of large vessels.
They are manual operated or fitted with PID programmer.
Ruggedly constructed but highly portable, they
give a long lasting service. Since
the heater elements operate at 230Volts, all control
panels are fitted with Earth Leakage Circuit Breakers
(ELCB) for additional safety.
Temcon 60 and Temcon 100 are fitted with contactorised
control modules. Energy regulators are fitted
for control of Heat Treatment Cycle. Miniature
size temperature controllers can also be fitted
on request.

C] FINGER ELEMENTS:
Finger elements are well established pre and
post weld heaters, suitable to be powered from
AD/DC welding machines or power sources.
Ruggedly constructed, they require minimal maintenance
and are capable of withstanding considerable on-site
maltreatment.
The element consists of two solid drawn Nickel
Chrome element wires passed through sintered alumina
beads providing electrical insulation and high
heat transfer capability.
Standard element maximum working temperature
is 1050ºC each finger being rated at 120
Amps at 1.3 Volts.
For heat treatment of stainless steel, special
solid drawn Kanthal wire is required to give a
maximum operating temperature of 1250ºC.
Steel connector blocks or twist-lock connectors
are provided for end termination.

D] CHANNEL HEATERS:
Channel Heaters are main voltage heating elements.
The elements can be connected in ‘STAR’
or ‘DELTA’ and operated from 380/415/440V
3 Phase supply.
They can be used to heat-treat circumferential
joints of large vessels using ‘BULKHEAD’
technique or can be used for building temporary
furnaces for Heat Treatment at site.
Portable and easy to handle, they have a long
on-site working life and are suitable for a variety
of applications.
Channel heaters are most suitable to be used
with Temcon 60 and Temcon100 control panels. Working
temperatures of up to 800ºC are permissible,
but higher temperatures can be achieved using
Kanthal wire as alternative element material.
Steel connector blocks or twist-lock connectors
are provided for tail terminations.
