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.
