YD 1178 FL
Water-cooled triode for industrial RF heating
31 kW triode for RF dielectric heating
Based on more than 60 years of experience in the design and
manufacture of electron tubes, Thales is a long-standing
partner to most producers of industrial heating machines. And
we are the benchmark supplier of grid tubes.
The YD 1178 FL triode is intended for low power dielectric
heating applications and delivers continuous RF power of
31 kW. It is especially well suited to industrial applications,
such as plastic welding.

This water-cooled triode uses a coaxial design and metalceramic technology. It may be operated in CW or pulse modes.
For operation in pulse mode, the parameters depend on each
equipment characteristics. Contact us for specific information.
Thales is fully committed to the long-term viability of tube
technology, and to delivering high-tech products based on our
proven expertise in complex processes. We offer the widest
range on the market, whether for dielectric or induction and
laser applications, backed by all the customer support and
technical assistance services you need.
