Ceramic Jacketed Heaters
Features
- Ceramic Jacketed Heaters are Excel's
premium product since Three decades
- Especially to heat the cylinders (barrels) on all
types of
plastic(s) processing machinery
- The key to the ceramic jacketed heaters is its
superior design to
save power
- Quter insulation jacket conserves energy
- Up to 30% of
power
consumption reduces
- Maximum watt density = 50 watts / square inches
- Note: In case
where high watt
densities are required, it is important that all heaters should beused
with appropriate, approved and precise temperature control/sensor
device(s)
- Maximum sheath temperature up to 800oC
- Use of special ceramic material "steatite" with high thermal
conductivity
- The model is designed and constructed with
special effective dual
insulation which reduces the rate of heat radiation/loss, resulting
swift rise in the temperatures of the object to be heated
- Uniform heat distribution throughout the barrel
- Reduction of thermal shocks on polymer melt,
resulting in
improved quality Good shine of your finished products
- Increases productivity
- Ceramic Jacketed heaters meet progressive
requirements of the
plastic processors
Working
Principle
The key to the ceramic -
jacketed heater is its superior design to save the power. It is
constructed with Excel's exclusive Dual Insulation - first is the
heater's built-in insulation and second is the jacket's insulation. The
heat transfer in the ceramic heater is by convection and radiation. The
heat dissipation from the heater's built-in insulation will be
prevented by its outer jacket. Hot air will be trapped between the gap.
The process of heat exchange is making a uniform layer of heat all over
the barrel. The jacket has insulation lining which further prevents
the heat loss. This process reduces the rate of heat radiation, resulting
in swift development of temperature. Quick response to temperature
controller will have more "off" cycles at maintained set temperature.
Result is saving of electric power.
