Micro Tube Heater
Description:
Micro Tube Heaters are manufactured in round, square or rectangular section to guarantee the greatest thermal exchange keeping an excellent efficiency and a good reliability.
These heaters can be manufactured with built in thermocouple J or K type.
Construction :
The resistive wire is uniformly distributed in a compacted MgO insulation, with a CrNi-steel outer protection sheath.
The heaters are annealed after manufacturing, thus acquiring a high malleability that allows their being subsequently bent into any complex shape, with extremely narrow bending radius
Applications:
1.For heating the nozzles of Injection Molding Machines.
2.Thin Walled Container Moulds.
3.Hot Runner Nozzles & Bushings.
4.PET Preformed Moulds.
5.Packaging industry.
6.Welding bars.
7.Rolls' heating.
8.Disks' heating.
9.Plates' heating.
Features
A very wide contact surface results in exceptionally high levels of thermal conductivity towards the body that needs to be heated.
Optimal insulation results in very long life duration.
Heavy-duty construction results in very high resistance to mechanical shocks.
Operation temperature up to 750°C (1300°F).
Optional built-in thermocouple for high-resolution temperature measuring (J-type standard; K-type on request)
