Ceramic Heaters, Ceramic Band Heaters, Heaters, Silica Heater, Immersion Heater

The HOTWATT Ceramic Heaters are specifically designed to replace and upgrade your Mica Band Heaters on your Injection and Extrusion machines. The body of the Ceramic Band heater is constructed of precision made segmented ceramics, which add flexibility and allow for easy installation. The ceramics are covered with insulation, which serves to lower the shroud temperatures and concentrates the heat towards the barrel. The end results are less wasted energy, a lower wattage requirement and a longer heater life.

MATERIALS OF CONSTRUCTION :-
*Outer Sheath - Polished S.S.304
*Ceramics - Steatite
*Element - Resistance wire (Ni - 80 %, Cr-20%)
*Termination - Metal Braided Fibre Glass wires
*Insulation - Flexible Asbestos sheet or Ceramic Fibre covered with Aluminum foil to avoid black spots on outer sheath.
.
MANUFACTURING:-
Depending upon the Volt and Wattage a suitable size of the resistance wire is selected as per the recommendation of the resistance wire manufacturer. The coil of the wire is then passed through the ceramics to get a bed of the ceramics .The size of the bed depends on the dia and the width of the heater. This bed is then fitted into S.S. 304 sheath after Al.foil and insulation. The element wire is terminated on a brass strip from where the lead wires are taken out further. These strips are covered with a ventilated terminal box.. The heater is provided with a clamping device, which has a Cap Screw for easy, and even tightening of the heater on the barrel.

FOR BEST RESULTS:-
Clamp securely the heater to the object to be heated and run the heater at operating temperature. Retighten the bolts to correct the expansion due to heating. This will result in better heat transfer and longer life of the heater.
