Construction Characteristic

It is a second generation heater. Mfg for trouble free performance in operation involving heating of cylindrical surface where precise Temp. control is essential. Especially adapted as an alternate heat source of demanding and high temp. applications where other type of heaters have failed. The coil Heaters have opened revolutinized the plastic injection runnerless moulding industry. The specific way to improve coil Heater is design in rectangular mineral insulated cable which has a flat surface contact allowing better heat conduction & faster start-up time. The coil Heater has lend themselves to a wide range of appliction. The flexibilty of mineral insulated cable allows the heater to be coiled , formed, wraped around cylindrical object. The heating source for the coil Heater is a resistance wire to the specific Heater design. The coil Heaters where wire wound resistance coils are used, the tail end of the heaters is usually unheated. The drawing process involved in manufacturing the coil Heaters compact the ceramic insulators that house the Heating element into a solid mass. Providing excellent thermal conductivity, dielectric strength and quick response.

Application

The Cioil heaters for plastic injection runnerless moulding bushings & for internally heated injection M/c nozzles.

The inside diameterof a coil Heater is wound under seized for a screw-on fit.Therefore hold down fittings are not usually required.

Uses :Immersion heaters are the heaters which are used mainly for heating water, oils, mineral oil, vegetable oil, fuel oil, chemicals, alkaline, acidic & non-acidic solution kept in tanks.
Construction :The immersion heaters are sheathed in S.S. or mild steel or incoly tube or copper as per the requirement. The dia of tube is available from 8.2 mm dia onwards. This heater is fitted to the tank through a check nut for horizontal (through the side) mounting or with flange for vertical (over the side) mounting. The size of check nut or flange is 1¹/₄" to 2¹/₂BSP.
Electrical Data :In any voltage & wattage depending upon the surface area of heaters.
Working Temperature :The temperature of immersion heater could go upto 600C depending upon sheathed material & process application.
