HEAT SOURCE

Tardeo, Mumbai, Maharashtra

Being sheathed on one side only, it has very little residual heat and stands up to 650C temperature for its surface area. Elimination of the sheath on the contact side puts the rock hard refractory in direct contact with the heated surface, thereby providing slightly faster heat-up. Half Sheath elements can be used where the protection provided by the full sheath is unnecessary.

Fully Sheathed Heaters (both sides metal) provides extra protection from rough handling & usage, especially when there are chances of falling any liquid on it.

High-wattage cartridges belong to a new generation of electric heat-ing elements; they make it possible to use high watt loads in small spaces, thus ensuring excellent reliability in heavy-duty work condi-tions. Their special construction technology makes them the most advanced type of heating elements. The entire length of the wire wound around a magnesium oxide core is in a far away position from the axis of the cartridge, very close to the metal sheath, with a very thin and compressed insulating wall in between; this allows excellent heat exchange that allows a much lower temperature of the resis-tance wire than in other heaters in which the wire is in a deeper posi-tion. Besides the use of advanced technology and precise inspection techniques in their manufacturing.

1. The hole where it is going to be isntalled, the cartridge must have a diameter tolerance between 0.02 to 0.06 mm (depends upon watt density, higher watt density must have lower tolerance).
2. The cartridge must not be longer than the hole where it is installed.
3. Connecting leads must not be scratched, flattened, stained, wet, etc.
4. The cartridge heaters cannot work in open air.
5. Controlling systems must be used with the cartridge heaters.
6. Resistance Tolerance: + 10% - 5%
7. Wattage Tolerance: + 5% - 10%
8. Length Tolerance: +/- up to 5mm
9. The sensors for the controller should be placed between the working surface of the part & the heaters. The temperature of the part approximately half inch away from the heaters is used in selecting maximum allowable watt density.
10. Control of power is an important consideration in high watt density appl cations. On/Off control is frequently utilised, but it can cause wide excursions in the temperature of the heaters & working parts. Thyristor power control are valuable in extending the life of the high watt density heaters, since they effectively eliminate On/Off cycling.

Heaters are used in various applications, due to their being intrinsically reliable and highly versatile. They were first designed for a very specific application, the differential heating of plastic injection nozzles, and later become invaluable in the most diverse and demanding applications. Aerospace, railway, chemical, metalworking and food industry, glass and paper indus-try, automotive, packing, medical industry. all have taken advantage from the use of heaters, with their wide range of possible shapes and their fitness to an unlimited number of applications.

Microtubular coiled heaters are manufactured to a revolutionary design, which makes them the best choice in the most demanding conditions. The resistive wire is uniformly distributed in a compacted MgO insulation, with a CrNi-steel outer protection sheath. The heaters are annealed after manufacturing, thus acquiring a high malleability that allows their being subsequently bent into any complex shape, with extremely narrow bending radius.

1. A very wide contact surface results in exceptionally high levels of thermal conductivity towards the body that needs to be heated.
2. Optimal insulation results in very long life duration
3. Heavy-duty construction results in very high resistance to mechanical shocks
4. Operation temperature up to 700C (1300F)
5. Very low mass results in extremely low thermic inertia
6. Optional built-in thermocouple for high-resolution temperature measuring (J-type standard; K-type on request)
7. Unlimited range of possible shapes obtained from the straight heater
8. Heaters can be incorporated into brass or aluminium castings
9. Available in cross section 2.4mm x 4.2mm & 3.3mm x 3.3mm.

The quartz glass is very pure and provides good transmission and temperature resistance

The unique twin tube design offers high radiation power and very good mechanical stability allowing emitters of lengths up to 3.5 meters. Emitters are available in Short Wove, Medium Wave, or Long Wave versions. That gives you the possibili-ty to select the optimum wavelength for the material to bo hooted. Dimensions and filaments are matched to requirements.

Twin Tube Infrared Heater is made by virtue of a gold & white coated which con emit heat directly to the product. A coat-ing on the infrared emitters reflects the infrared radiation. Consequently the infrared radiation impinging on the product is virtually doubled.

• Infrared heaters can be matched to material characteristics - following higher process speeds and less energy consumption
• Directed heat only where needed
• Infrared ovens needs less space
• Non contact or medium needed
• Short response times of infrared heaters for switch on / switch off

Versatile in shape & loading. Sheath material suitable to the application and temperature for variety of heating application.

Single Ended Tubular Heating Elements are of similar construction as our standard tubular elements. They terminate at one end which can simplify wiring and installation. These are most commonly used in moulds and other heat transferring metal parts as well as open air applications and immersion applications. Tubular Heaters are available in a variety of sheath materials with temperature capabilities up to 870C

Specialty Shaped Tubular Heating Elements are of similar construction to our standard tubular elements. These shapes can greatly increase rigidity to the element. Heaters that are clamped to a surface have greater surface contact allowing for greater heat conductivity. Tubular Heaters are available in a variety of sheath materials with temperature capabilities up to 870C
