About the RS 3700
The RS 3700 is a power triode manufactured by Thomson / Thales. Thales RS 3700 water-cooled metal-ceramic triode, one of the largest in the RS series, for continuous duty ultra-high-power industrial RF heating installations.
Key ratings of the RS 3700 include tube type Triode, construction Metal-ceramic, anode cooling Water, cathode Thorium tungsten and max frequency 100 MHz.
Typical applications are ultra-scale industrial RF, continuous duty mega-power heating, large industrial manufacturing and ultra-high-power RF generators. Notable features: RS 3700 large-format triode, water-cooled anode, metal-ceramic coaxial and continuous industrial duty.
Power triodes are three-electrode grid tubes used as RF oscillators and amplifiers in industrial RF heating (plastic welding, induction heating, drying), RF-excited CO₂ lasers, broadcast transmitters and particle accelerators. In oscillator service they work with vacuum capacitors in the tank and matching circuits.
PartnerTubes supplies the RS 3700 worldwide from Groningen, the Netherlands — availability, lead time and price are confirmed per enquiry. Our team can help with equivalent and cross-reference types, sockets and accessories, and supply programmes for OEM and maintenance customers. Interchangeability must always be confirmed for the specific equipment.
