About Energy Technology:

Specialized in researching and manufacturing oxy-hydrogen generators, our company takes possession of many patents as follows.
1) Patented Integration of Water Electrolysis Cell Forming
Our electrolysis cell Integration is used by Large Module in order to ensure "No Leakage, Explosion-proof, Long Life Cycle".
2) Patented Electrolysis Power Supply based SCM
Our Power Supply is specially designed for Electrolysis.
For Example:
2.1 Constant current control by temperature feedback control
2.2 Current adjust by users to meet the constant flux of oxy-hydrogen gas
2.3 Efficient energy conversion (AC TO DC) based IGBT
2.4 Special cooling design for working 24 hours continues
3) Patented Multi-layer ANTI-FIRE Water Seal Technology
Water Seal Device is an important unit of oxy-hydrogen generators. This unit is designed for backfire-proof and it works 100% OK.
4) Automatic Water Level Detection Technology
We design it by ourselves, and it is used for detecting the water level of electrolysis cells and water-deposit tanks. When water height is too low, the alert lamp will be turn up. When water height is the lowest, the power supply will switch off to proof the oxy-hydrogen generator.
5) Water Automatic Replenishment Technology
When water height of the electrolysis cell is too low, the system will start automatically to pump water from water deposit tank.
6) High-efficiency Gas Water Separator Technology
This Technology is used to separate the water from gas and ensure the gas purity. If oxy-hydrogen gas has some water (even little), the temperature of the oxy-hydrogen flame will become lower.
7) Electrolyte - Automatic Cycle Technology
We realize Electrolyte Cycle by the static way. Don't use the pump, because the pump is a mechanic unit which is easily damaged.
