Ceramic Heaters .
This is an advance version of perforated ceramic heaters this works on a principle of forced convection for quicker response to overheating and accurately controls temperature of barrel. as soon as barrel exceeds set temperature, blower is turned on. excess heat from barrel is carried away be the air through faced convection. via rapid heat up and accelerated cool down feature, it responses very quickly in case of even a minute deviation from set temperature. thus it reduces thermal shocks, material burn-out problem and maintenance related problems.
