Radiant heaters


Description

Radiant heaters made of silicon nitride are normally rectangular. Various dimensions and batch sizes up to our die diameter of 400 mm can be produced. These heaters have a hot zone with a range of operation up to 1 000 °C and a cold zone in the contact area. For a range of operation up to 500 °C large flat heating elements without a cold zone can be supplied. The special properties and low mass of the ceramic material allow fast heating rates, uniform temperature distribution and outstanding precision in control. The high emissivity and wide emission spectrum of thermal radiation make the ceramic material, which is manufactured out of a nearly black silicon nitride, an ideal radiant heater. A radiation power of 15 W/cm² at 1 000 °C can be reached.


Customized design

Our in-house designs make any modification in size, configuration, or performance simple and convenient. Holes for temperature measurement can be included. Large heating areas can be achieved by assembling several radiant heaters. For reaching a uniform temperature distribution or desired temperature areas, the power input can be adjusted to the heat radiation. For operating in high vacuum or inert gas at up to 1 000 °C a purpose-built and well-tested pin contact can be supplied.
