Microwave plasma Microwave plasma, along with RF systems, is one of the only electrode-free
sources of chemically pure plasma with virtually unlimited operational
lifespan. The main difference between microwave (MW) and radio frequency (RF)
plasma systems lies in their operating frequencies. MW systems operate at
frequencies ranging from hundreds
of MHz to tens of GHz, with power levels from hundreds of watts up to 100 kW per unit (generator output). In contrast, RF plasma systems
also start at a few hundred watts but can reach power levels of 1–1.5 MW. For customers who do not yet
require megawatt-scale power, we offer a range of plasma sources with MW
generator output power options of 1 kW, 10 kW, 50 kW, 75 kW, and 100 kW. These generators can be based
on either magnetrons or solid-state technology. Magnetron-based generators
provide simplicity, compact size, minimal cooling water consumption,
reasonable cost, and acceptable efficiency. However, they require replacement
every 2,000–5,000 operating hours. Solid-state generators, on the other hand,
offer a significantly longer lifespan (up to 50,000 hours), approximately 5% higher
efficiency, but come at a 50–100% higher cost and require significantly more
cooling water.
Our first MW plasma torches were
developed in 2011 and have since distinguished themselves from competitors by
offering high plasma stability and thermal efficiency. This is achieved
through our patented reverse vortex plasma stabilization technology for high
plasma gas flow rates and an ultra-efficient swirl system for standard flow
rates. Find more details on Atmospheric
