Plasma Torch

Plasma can be generated in several ways for various processes and applications. Our tailor-made solutions intervene in the powering of plasma torch. High heat process: A thermal plasma torch is generally powered by a DC power supply from few tens of kW up to several MW. A gas is pushed through the torch and transits inside it, where an electric arc is generated by a DC power supply to reach a temperature range of 5.000 to 10.000°C at the exhaust. This generated heat enables to separate the atom nucleus from their electrons. Therefore, new molecules can be produced for different purposes.
