High Pressure ICP/RF Plasma Torches Applied Plasma Technologies, Corp. (APT) stands as the sole supplier offering Inductively Coupled Plasma (ICP) torches—also known as Radio Frequency (RF) torches—that operate across a broad pressure range (from several Torr to 7 bar) and deliver plasma power from 15 kW to 200 kW, all while ensuring over 10,000 hours of continuous operation. Originally developed for coal gasification, our RF torches exhibit minimal sensitivity to pressure variations. Upon request, we can also provide plasma systems capable of operating at pressures of 30-40 bar. Our RF torches are crucial components in a wide array of advanced applications, including waste processing, coal and biomass gasification, fuel reformation, plasma chemical processes, metallurgical treatments, coating, heating, melting, and cleaning. They enable the synthesis of new materials such as isotopes, nano-powders, and nano-tubes, and offer fuel flexibility for Solid Oxide Fuel Cell (SOFC) systems. Looking to the future, ICP/RF torches are expected to play a key role in high-power thrusters for deep space missions. The plasma's versatility allows for the use of nearly any interplanetary gas as propellant, enhancing RF plasma's potential for planetary life support systems. Our patented high-power RF torches, featuring triple vortex plasma stabilization (US Patents 7,452,513 B2, 7,955,567 B2, and several patents pending), offer unparalleled efficiency in both thermal and electrical performance. They produce pure plasma with temperatures up to 12,000°C, free from contamination caused by electrode erosion, and boast a virtually limitless lifespan. These RF torches can be integrated with remote discharge initiation systems, nozzles, swirlers, and multi-stage downstream reverse vortex reactors to achieve highly effective plasma mixing with gases, liquids, and solids, supporting "cold wall" operations. For a view of a 500 kW multi-purpose atmospheric pressure torch with a water-cooled extension nozzle, see the image to the right. We offer a commercially available system for the destruction of contaminated liquids, including sewage sludge, which utilizes a 50 kW torch coupled with a multi-stage reactor. Additional high-demand systems include the elevated pressure APT-100 and the higher power APT-125, designed for nano-structured material production. These systems feature a dual-modular power supply with coaxial cable for flexible connections, a capacitor bank with a 50 kW high-pressure torch mounted on top of a high-pressure reactor, and an optional multi-gas control system. Click for detailed specifications on all APT-100 modifications. For more powerful options, our APT-200/250 systems are ideal for powder treatment, high-concentration NOx production, thermal protection material testing, and nano-tube synthesis. Starting in 2023, we offer container packages for both APT-100/125 and APT-250 systems to accelerate their deployment. We are also developing the APT-500 and APT-700 systems, which will feature advanced control systems for unmanned remote operation, integration into any customer plant management system, and Wi-Fi control capabilities. Our latest endeavor is the creation of the world’s first RF plasma hub at our new facility in Marshall, VA 20115. Phase 1 of the construction is complete, featuring 4,000 sq. ft. of test bays for simultaneous operation of three plasma systems ranging from 100 kW to 1 MW. Interested customers can lease both plasma torches and test cells, and receive support from our specialists, CFD modeling group, designers, and on-site prototyping machine shop.
