It is designed for commercial trucks, buses, Heavy Duty engines in construction and agriculture machines, marine engines and other vehicles with engine displacement from 10.000 to 16.000 cc. The device produces 500 to 800 liter per hour of “HHO” – Oxy-Hydrogen gas, as additional fuel for all diesel and gasoline engines.


This device is a product of years of scientific research in the field of water electrolysis. We have came up with new scientific discoveries and get the result in the form of products that cannot be classified as a dry “HHO” generators and neither can the submersible called wet “HHO” generators. “HS-VG 720″ is a dry generator which is submerged in the liquid and we could call it “Flooded – Dry HHO” Generator. “Dry” means that his chambers are galvanically isolated from each other.

Projected like this, the device does not consume the electrodes and do not overheat the device. Electrolyte mixture, potassium hydroxide (KOH) and distillated water in concentration of 20%, which provides resistance to low temperature, up to 17 degrees Celsius below zero. Below this temperature, by adding the special liquid from the instructions for use, the device is resistant to freezing at temperatures below 40 degrees Celsius below zero.
