Water Cooled Ignitron Tubes

Darrah provides a complete line of Solid State SCR Ignitron Tube Replacements for Ignitron sizes A through Super E. Replacements are available in both water cooled and air cooled designs, and easily mount on existing Ignitron Tube brackets. Darrah’s single assembly replaces two tubes.

Solid state replacements are more efficient and less costly than ignitron tubes, and contain no mercury.

Darrah's replacements are engineered so that no modifications are required to existing controls or timer. Replacements are supplied with MOV, voltage suppressor and normally closed thermostat.

Simple installation instructions are included. Thousands have been sold and installed.
