CPI 3CW45

The 3CW45,000H3 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 45 kW of plate dissipation with low water flow and pressure drop. The removable water
jacket (SK-1360 - not included), allows inspection
and cleaning of cooling passages as well as reducing tube replacement cost. A glazed ceramic is
used to make insulator cleaning easy. Input of 150
kW is permissible up to 75 MHz. Plentiful reserve
emission is available from its 1600 watt filament.
The grid structure is rated at 750 watts, making
this tube an excellent choice for industrial service.
