Integrated Sheath MI Heating Elements

Enhancing Reliability Through Seamless Design

Our latest innovation in Mineral Insulated (MI) heating technology features a jointless, integrated sheath design that eliminates the traditional welded or soldered connection between the hot and cold sections. The result is a more robust, efficient, and versatile heating element that improves reliability in demanding applications.

By maintaining the standard cold tail and lead configuration, the new design offers a drop-in replacement for existing heater assemblies while delivering superior mechanical strength and performance under thermal stress.

Key Advantages
• Seamless construction – Continuous sheath eliminates internal joints, removing a common point of failure.
• Improved thermal contact – Enhanced heat transfer efficiency, ideal for tight or precision fit applications.
• Greater mechanical flexibility – Suitable for intricate bending and custom feed-through heater designs.
• Higher vibration and thermal cycling resistance – Improved integrity under repeated heating and cooling cycles.
• High-temperature capability – Operates at sustained temperatures up to 700°C (exposure to 1000°C).
• Easy integration – Retains standard cold tail and lead design, simplifying installation and retrofit.

Typical Applications
• Feed-through and immersion heater assemblies
• Process temperature maintenance
• Frost and condensation protection
• Hot water and pipeline heat tracing
• Leak detection and industrial heating systems
• Electronics and satellite thermal control systems – maintaining stable operating temperatures by heating media to regulate sensitive onboard electronics

Technical Specifications
• Sheath materials: Stainless Steel, Inconel, Alloy 825
• Voltage rating: Up to 750V
• Power output: Up to 300 W/m
• Temperature range: Continuous 700°C / Maximum 1000°C
