The extreme high output of borium nitrate heaters, also referred to as High Flux of Very High Performance Heaters, is achieved by using borium nitrate technology which ensures that the Nichel-Chrome 80/20 spiral unrolls its heath within the heater. This is the so called Joule effect.

Depending of the conditions of use (convection, conduction or radiation) and the surface temperature of the elements, the watt density (specific heat) of borium nitrate heaters can go even over 150 W/cm2.

The team of specialists of Heating Group International is happy to give you advise for your specific situation and if borium nitrate heaters can be a good option for your process too.

In the past years Heating Group International has delivered multiple projects with borium nitrate heaters for applications with high circulation speed, high pressure and temperatures up to 1100°C in projects for turbines, power plants, reactors and for forges.

Another typical use of borium nitrate heaters is the use as boltheaters. In this case the borium nitrate heaers are used as cartridge heater to heat up bolts and nuts, or as straight tubular elements at forced convection within electric heaters. Traditonally hollow bolts were heated up by inserting a heating element isolated with magnesium oxide.  Our promiss to you: the use of Heating Group International boltheating with borium nitrate technology reduces the assembly time (tightening of the screw connections) and dismanling time (loosening the screws) significantly.
