The unique properties of mineral insulated heaters deliver definite benefits when high operating temperatures are required in industrial/commercial processes. Mineral insulation (MI) materials offer enhanced thermal conductivity in comparison to traditional mica and hard ceramic insulators. This type of industrial grade, mineral insulation supports efficient heat transfers, even distribution, and longer product life. MI heater applications include:
- Extruders
- Blown film dies
- Injection molding machines
- Other cylinder heating applications
Due to their temperature control capabilities, heaters with mineral insulation can support greater productivity. Our MI band heaters are specially designed for applications featuring high watt density and/or high level operational temperatures. A mineral-insulated band heater can be securely clamped on a cylindrical shape, allowing for optimal heat transfer. If you need information on the premium performance of these thermal products, contact our knowledgeable staff. We’re dedicated to providing exceptional Hi-Watt customer service as your trusted distributor of process heaters.
