The world's first high voltage electrical heater for use in the processing of raw materials was designed by SAN
The world's first high voltage electrical heater was delivered by SAN in 1986. This equipment was developed by SAN's engineering department, and won the Danish Engineers' Association Prize for electrical innovation in 1988.
The unit is built with 2 independent insulation systems, where the material is itself both an electrical and thermal insulation.
To facilitate service, each of the 14 sections is mounted on rollers, and can, with little effort, easily be rolled out of the heater.
This equipment is fitted with pyrometers to measure temperature levels in the heating elements.
