Description:
Split Sheath Cartridge Heaters are tubular heaters that have been formed in to a half circle which is then folded in the middle with the two halves now making a circle.
When heat is applied, the two domed arms of the cartridge heater move outwards to the surrounding holes walls to create a very close fit. This maximizes surface area contact along its length greatly improving the heat transfer, while also prolonging the life of the heater as it prevents overheating sections forming hot spots due to air gaps may occur.
When the cartridge cools the arms retract to their original diameter, reducing the fitting tolerances for easier removal. This saves time and money reducing your overall maintenance budget, including interruption to production and repair of the bore etc.
Feature
1. Our Heaters expand to fit the hole, helpful in larger holes & those that are a loose fit due to wear are tear or drilled out holes.
2. Supports Faster & Easier Extraction, as our Split Sheath Cartridges close together when cool, reducing the diameter & loosening the fit within the hole. So no need for drilling out the cartridge or using lubricants. Saves a lot of time & effort.
3. Allows trouble free use in longer holes, as the split sheath design increases the cartridges rigidity, so prevent bending therefore keeping a flatter profile enabling a better fit.
4. Due to the split sheath expanding & contracting its diameter, there is no need worry about tight tolerances i.e. a loose fitting or drilled out hole.
