The maximum Surface Temperature is 1450°C  which cannot be exceeded. Use beyond 1400°C surface temperature is life-limiting. A pyrometer in a free radiating condition or a thermocouple in an enclosed condition is recommended for use if operating above 1200°C to prevent inadvertent burn-out. The use of MHI controls is highly recommended.

Simple power and voltage calculator for the patented MagnaCoil™ is given below. Note that free radiating and enclosed heating objectives have different power demands.

The Power of a MagnaCoil™ depends on the Diameter Di and N and the number of turns. Note that N is not an integer for IMC or some MC models.

Maximum Power = (50-25) N P Di Watts (Di in inches). The range depends on the enclosure used. The highest Power for unenclosed (free radiating) is the objective in a free radiating condition. Providing a section changes the aim to temperature instead of Power. As the temperature is achieved, the power demand equals loss of Power from the enclosure and P =3.1-3.2. See also the radiation page.

Maximum Voltage V= N P Di/(2-3) Volts, Di in inches. The range depends on the enclosure used. 

Maximum MagnaCoil Surface temperature is 1450°C.  Use beyond 1400°C is life-limiting

Free radiating Power is the Power dissipated by the coil when there is no surrounding refractory enclosure.

Vertical configurations and stress may reduce the use temperature.

CHS-OD or equivalent spacers are recommended when creep deformation is possible.

Note that coil temperature and environment temperatures will be different.

feedback controller is highly recommended for managing the coil temperature. For small coils

BPAN controller is recommended.

Coil temperature is best measured with a pyrometer with feedback control BPAN.
