Liquid-cooled starters - GINO AG

For liquid starters, the electrolyte solution of Na 2 CO 3 acts as resistor, which in turn depends on the soda concentration. By changing the distance between upper and lower electrodes, the resistance is reduced smoothly. In addition, the fluid acts as a store of heat energy, which occurs during start-up, and this is slowly released to the ...
