Mineral insulated heating cable 1000°C

Mineral insulated heating cable, also called MI-cable, is a series-resistant flexible heating cable with outer shield of stainless steel, copper-nickel or Inconel®. MI-cable is manufactured in the same way as a tubular heater, with spiralized resistance wire surrounded by magnesium oxide as an insulator and an outer shield. The small diameter allows the MI-cable to be bent and shaped according to the object to be heated. The transition between hot and cold parts is laser welded and can withstand a heat exposure up to 1000°C.

Common uses of mineral insulated heating cables are heating of process pipes and valves, heating panels, vacuum techniques, molds, underwater radiators, reactors, sodium transportation pipes, salt transport for curing bainite, bitumen plants, gas plants and refineries etc.

Mineral insulated heating cables transmit very high power and temperature and have excellent corrosive protection properties against alkalis and acids.

IHPs mineral insulated heating cables are available in many standard lengths and can also be adapted to demands and needs for both safe and explosive-rated environment.

Bellow a list of our most common resistance wires and the relation between the MI-cables outer diameter and minimum bending radius.

Control cabinet PID

IHPs smallest control cabinet is a “stand alone” system that fits a variety of heating applications where the need is one heating zone and one sensor. In our PID controller there is plenty of intelligence that comes in handy when needed for even heating, ramp functionality, maximum adjustable temperature, program steps with different set points or only temperature control that is CE marked and approved.

We supply the control cabinets in three standard versions and you simply select the cabinets according to the type of sensor that fits your process. IHP can also offer some popular options such as quick plug between heater and control cabinet and help program the control cabinet with the parameters that are important in your process.

The control cabinet can advantageously be used in conjunction with all IHPs heaters that need less than 16Ampere.
