We are specialized in researching and manufacturing Oxy-hydrogen Generator, Water Welding Machine, Flame polishing machine and other products. We have kept in close cooperation with institutions of higher learning fields for several years. Furthermore, we are keeping devoting to improve old products, developing new products, and doing our best to meet the market demand. All of our products are manufacturing in accordance with international quality management system and will do rigorous tests before delivery.  We have 5 national invention patents and 3 utility model patents. We have a professional technology development team which has 20 technical personnel, more than 50 production staff. We can produce 200 units hydrogen generator per month to meet the needs of customers. We have passed ISO9000 quality system attestation. Our Products can run 24 hours continuously and the main machine can run over 5 years. Many clients have purchased our machine for six years and it is still in good condition. At present, we can provide two series of type products: small portable type oxy-hydrogen: OH100, OH200, OH300, OH400, and medium type oxy-hydrogen: OH1000, OH1500, OH3000, OH5500, OH7500, OH10000. About OKAY ENERGY Technology Okay Energy Co., Ltd, which is specialized in researching and manufacturing oxy-hydrogen generator, 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 make sure 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 user 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 generator.   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 the electrolysis cell   and water-deposit tank.   When water is too low, the alert lamp will be turn up. When water is lowest, the power supply will switch off to proof the oxy-hydrogen generator. 5)  Water Automatic Replenishment Technology      When water of the   electrolysis cell   is too low, the system will start up automatically the 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 pure.   If the 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 static way, don't use the pump. Because the pump is a mechanic unit which is easily damaged.
