FAQ's for UltraCoil™:

UltraCoil™ Free Radiator Configuration (figure 1)
UltraCoil™ Enclosed Refractory Configuration (figure 2)

1. If used in an enclosed refractory configuration (see figures below) the temperature of the enclosure which can be achieved has to be calculated carefully and depends in the type of enclosure, the thickness of the enclosure and the power available from the coil. Please contact MHI for this calculation for your specific application.
2. At the temperature of use, after a steady state condition has been reached, the free radiator configuration will draw more current than the refractory encased configuration. See example below.
3. MHI can supply the ceramic enclosure, caps for the enclosure and the complete electronics required. Please contact MHI for a detailed quote or for Robust Radiator.
4. Most important: Do not exceed 96A on coil in the free radiation configuration (figure 1)
5. Not for use below 800°C coil temperature.
6. Do not exceed 1700°C in chambers of the enclosed refractory configuration (figure 2)
7. Do not exceed 1850°C on coil. If higher coil temperatures are required, please contact MHI. MHI coils are designed for minimal creep, however specially with temperatures close to the maximum operation temperature, creep is a factor to consider.  Often this depends on your application.  MHI can provide some guidelines based on experience but may not be in a position to determine the extent of creep in your application.
