Electro Discharge (EDC)

A very powerful process capable of extremely high impact pressure required in many specialized applications.

Technology Summary

The Electro Discharge technology is simply two electrodes placed in a specially designed nozzle utilizing our proprietary discharge process. The nozzle contains either water or water flowing at low pressure. The capacitors are charged to required the voltage and the electrical energy is then rapidly transferred between the electrodes by a switch.

Like a spark produced by the spark plugs in a car cylinder, an electric arc is formed between the electrodes. This arc generates a very hot steam bubble (plasma) which attains a diameter of about 33,000 feet (~10,000 meter) in less than one second.

Escaping through the nozzle, this bubble discharges the water in front of it at a very high speed (> 1,700 meters per second). Literally faster than a bullet, when this high-speed water droplet hits the target, the extremely high impact pressure breaks the target into pieces.
