TYPICAL CLAMPING OPTIONS FOR ALL BAND HEATERS
C1
Standard Allen Bolt Clamping Type
Allen bolt with standard clamping systemgenerally used on all heaters.
C2
Spring Loaded Clamping Type
Allen bolt with spring loaded clamping systems provides excellent grip of the heater mounted vertically.
C3
Separate Clamping Strap Type
Screw clamping system with ears on external casing of the band.
C4
Flange Bolt Nut Type (Mica Band only)
An external strap Allen-Bolt casing of stainless steel sheet suits for maximum thermal efficiency makes a pressure on the heating band.
TYPICAL TERMINATION OPTION FOR ALL BAND HEATERS
T1
Post Terminals (Screw Terminals)
Post terminal provide optimum connection. Ceramic covers with opening for leads are screwed onto post terminals providing a convenient, economical insulator can be provided on heater length of 40mm or more.
T2
Ceramic Connector Block
Ceramic connector ranging upto 15 Amps with brass pins directly mounted on the edge of heater connected with stainless steel lead insulated with F/G sleeves generally used where long leads wire is required.
T3
Terminal Block
Customized metallic terminal box attach directly to the heater & act as a safety features by covering the MS SS Bolt acting as a terminal for heavy connection loads this can be provided on heater of the length 40mm or more with standard 1 meter fiber glass insulated lead wires.
T4
Fiber Glass Lead Wires
Standard connection pure nickel wire directly fixed with heating wire coming out crimped with copper conductor lead wire insulated with 1Mt. fiber glass having shock absorbing T-Clamp. Generally used where long lead wire is required.
T5
Fiber Glass wires with SS braided sleeve & T-Clamp
Standard connection pure nickel wire directly fixed with heating wire coming out crimped with copper conductor lead wire insulated with 1Mt. fiber glass having shock absorbing T-Clamp. Generally used where long lead wire is required. Direct Fiber glass lead connections as described above are shielded with protective SS Braided sleeving.
T6
Plug Type (Male Plug)
This provide the simplest and fastest way to apply power to band heater. This assembly eliminates all life exposed terminals and electrical wiring that can be potential hazard to employees or machine. Can be provided on heater length 40mm or more.
CERAMIC BAND HEATERS
Construction:
Matrusree Ceramic Band Heater,
High Temperature Resistance Wire is embedded in a flexible outer wall made
ofspecial, interlocking ceramic tiles, which are assembled like a brick wall. A
ceramic fibre insulating mat and astainless steel jacket cover this assembly.
This construction prevents heat loss and reduces electricalconsumption by 20%.
An energized ceramic band heater will have a temperature of 200 Deg C on its
outside shellwhen the inside temperature is maintained at 550 Deg C. To improve
the conservation of energy, differentthicknesses of ceramic fibre insulation
mats are available. Heat is transferred from a ceramic heater to thesurface of
an application through conduction and radiation.
Ceramic
Band Heaters are made by using different combinations of ceramic tiles, which
are available only inspecific lengths. Consequently, the width of a Ceramic
Bands falls within a certain incremental range. these canbe manufactured with
different clamping mechanisms, termination styles, holes and cut-outs.
