Definition of plasma

High temperature plasma arcs are heat sources of unique functionality, intense power and versatility; they combine the clean heat of an electric arc with the stability, directionality and control of a gas flame. The result is heat that is generated without combustion, and as such, plasma does not involve any form of incineration.

Power and control are brought together utilising years of experience in equipment that is able to withstand the most hostile of environments to provide our customers with high technology solutions for their processing needs.

One of the key features of DC Plasma Arc Technology is its great versatility. It can be used purely as a clean, controllable heat source, whereas other alternatives such as oxy-fuel heating can lead to contamination of the product, or as an environment for carrying out plasma-phase reactions which would not be possible using conventional heat sources. It can be operated at a range of pressures from 10 Pa (0.1 mbar) to several atmospheres using inert or reactive gases. It can be used with conductive or non-conductive melts or in the complete absence of a melt phase. The absence of combustion means that temperature and process chemistry can be controlled independently; it also means that the quantity of off-gas is greatly reduced, leading to closer process and environmental control, better compliance and reduced plant operating costs. It can be used in conjunction with solid, liquid, gaseous or mixed feed materials, including metals, ceramics, glass and organic materials. Its versatility means that it can be applied to almost any feedstock.

Whether you require a plasma arc system for use in an existing plant, or in a new installation, for contract research or as an off the shelf package, Tetronics can provide you with a solution from 30 kW to 8 MW and beyond, backed up by the confidence that has evolved from satisfying demanding customers around the world for over 40 years.
