The expandable cartridge Heaters solve two major problems with conventional high density compressed heaters, poor durability fit and proper fit extraction, improving the accuracy of the temperature with hundreds of termination.
With the expandable cartridge heaters we join for the first time the best of the common cartridge heater with a cartridge and an adaptive tuning quick and easy removal.
The quality of the materials
The Expandable Heaters are manufactured with an internals compacting system of all its components in order to increase their lifetime. The Nickel/Chrome 80/20 conductor wire is introduced into the cavities of a ceramic body which focuses the suitable separation in order to obtain a better isolation. Fully coated with magnesium oxide of high purity grain sized controlled to ensure the complete cartridge Expan filled. Later a compacting process and a rectification of surface until calibrated the desired size. And finally, a rigorous quality control that guarantees the best operation of the cartridge.
- Nickel/Chrome 80/20 conductor wire, melting point 1400ºC
- Grain sized Magnesium oxide
- Hard refractory paste
- Conducting wire
- Stainless Steel AISI 304/316/321/INCOLOY
- Ceramic core
- Hard ceramic head
The Expandable Heaters consist of a compressed cartridge heater of a high performance and made with the best materials with the particularity of being able to expand itself thanks to the fork-shaped tensioned in a point that allow the expansion and retraction of the cartridge.
