Mineral insulated micro heaters
Our mineral insulated (MI) micro heaters are bendable and can be custom designed to fit in small environments where every nanometer counts.
Micro heaters are made with a mineral insulated outer layer and metal sheath. They consist of one or two wires that convert electrical energy into heat. A resistance wire is connected to a conductive wire and both are insulated with pure magnesium oxide (MgO). The MgO ensures that the heating section is insulated from environmental conditions.
Product summary
- Suitable for applications where space is limited
- High degree of bendability
- Fast response rate
- Power efficiency
- Good mechanical strength and vibration resistance
Industrial micro heaters for challenging environments
Designed for precision and performance, our micro heaters are engineered to use in low-oxygen environments, including inert, reducing, and vacuum conditions. They are also fully compatible with hydrogen and argon atmospheres, making them versatile solutions for a wide range of industrial applications.
Furthermore, they can function reliably in environments that are extremely challenging: not only high temperatures but also for other reasons such as: corrosion and high pressure.
Reliable and consistent temperatures up to 1000°C
Micro heaters are high-powered and capable of being very precisely controlled even at temperatures of 1000°C. Other key characteristics include:
- Reliable and consistent output ensuring temperature uniformity.
- Function at a wide temperature range
- Seamless transitions between the hot and cold sections of heaters
- Hot and cold sections have equal diameters
- Suited to air, high pressure or vacuum
- Sheath materials provide resistance to different forms of corrosion
- Quick response rate
- Flexibility: these bendable heaters can also be coiled or cast in metal
- Extremely thin outer diameter (as small as 1 mm) means they fit in tiny, complicated spaces
- Consistent power output independent of temperature variations
- Pure and chemically stable, the magnesium oxide layer protects and ensures a long product life
- Good mechanical strength and vibration resistance
- Power efficient: heat is generated exactly where required, reducing power consumption
Application examples of MI microheaters
Micro heaters are highly versatile and can be customized for various high-end industrial applications. Their design allows for multiple installation methods, including:
- Coiled inside an object
- Wrapped around an object
- Fixed with welded brackets
- Secured with a clamp system
Microheaters are the ideal product for high tech industries
Semiconductor
Micro heaters are used in applications such as ion implantation or vaporizer and deposition systems. They are especially important where process stability is key such as wafer production.
Micro heaters can also be used in sputtering systems like PVD and CVD, used in thin film layers deposition.
Our custom made solutions integrate the mineral insulated heaters in the desired end product.
Research
Research institutes run projects for various industries. The micro heaters and heating cables offered by Kamet have a number of advantageous characteristics that can be relevant to this field. A few examples where MI heating has been shown to offer significant improvements:
- Liquid chromatography & gas chromatography
- Battery testing
- Fluid tank level indicators
- Isotope separators
- Diagnostic technologies
Aerospace
Aerospace industries rely on these small heaters in, for example, the extreme environment of propulsion systems.
In response to the challenges presented by this industry we have been able to create micro heaters that are now even capable of achieving temperatures up to 1400°C – 1600°C.
We offer solutions such as cathode heaters and special conductor cable for ion thrusters.
