Chromalox cartridge heaters are most frequently used for heating metal parts by insertion into drilled holes. The QST Split Sheath industrial heater is designed especially for platen, die or mold commercial heating applications where the holes are poorly drilled or worn through age. Independent expansion of each section of the QST when energized, creates intimate contact with the wall of the hole.
- Split Sheath design
- Improved conductive heater
- Easily inserted and removed from long holes
- Incoloy® Sheath for long life at extreme temperatures
- Compacted to maximum density for excellent element to sheath heat transfer and dielectric strength
