Control Systems

The operation of an electric heater is only as good as its control system, therefore a tailor made, first class control system is offered by Vulcanic TEE with a range of options from the simple on⁄off control, to the most sophisticated burst fire⁄single cycle thyristor control.
Load splitting requirements can be divided into stages to give multi-thyristor control and in addition, combinations of thyristor and contactor control can be supplied to provide a fully synchronised system and limit impact on the power generation system.
