CPI 3CW2500D3

The 3CW2500D3 is a water cooled, ceramic/metal, medium-mu power triode designed primarily for
use in industrial radio frequency heating services.
Its water cooled anode is conservatively rated for
3.0 kW of plate dissipation with low water flow
and pressure drop. This tube is a version of the air
cooled 3CX2500D3 and is recommended for industrial applications where reserve anode dissipation
is required. Input of 8.1 kW is permissible up to 110
MHz. Plentiful reserve emission is available from
its 232.5 watt filament. The grid structure is rated
at 75 watts, making this tube an excellent choice
for industrial service.
