Product Description
Use
l Plasticization cylinders for injection molding machines
or extruders
l Mica band heaters are the ideal solution for heating
cylindrical surfaces in many other applications
Advantages of the ceramic band heaters
l Excellent heat exchange to the cylinder
l Heating uniformity
l Long life of the heater (when properly used)
l Easy to install
l High mechanical resistance
l Constant quality with time
l It is very important underlining that for this heater,
heat exchange takes place both for conduction and
radiation.
l Energy saving is an important characteristic because
the ceramic fibre layer, placed between the ceramic
and the external casing, reduces of about 20%
energy consumption, if compared to a normal mica
band heater.
Diameters
l Starting from 70mm, for heaters whose diameter is
over 500mm is recommendable to manufacture
them in two or more different sector with separate
feedings
Widths
l In this case, widths are determined by the distance
between the holes inside the ceramic blocks and,
therefore, we have worked out the table at pag. 3
with the standard widths in mm.
Technical features
l Specific wattage up to 8 W/cm2
l Working temperature up to 420 °C
l External stainless steel sheet, resistant to high temperatures
(A)
l Nickel-Chrome 80/20 resistive winding (B)
l High purity ceramic insulation (C)
l Ceramic fibre insulation (D)
l Heater’s standard thickness 12 +/- 1mm
l Fibreglass insulated feeding cable with pure Ni or
CuNi conductor externally protected by a metal
braiding (built in earth wire) – working temperature
320°C , with peak 350°C.
l Options:
Pure Ni or CuNi conductors with silicon sleeve -max
working (Temperature 180°C, peak 200°)
