ZXD Separated Type Water Electrolysis Hydrogen Generation Equipment/System
The hydrogen generation capacity of single equipment is up to 20Nm3/h-1500Nm3/h, and hydrogen generation’s layout is achieved by station.
 The exterior of all stainless steel equipment has been polished which makes it good-looking.
 The electrolyzer adopts bipolar filter pressing structure, and the insulation of sealing gasket is strong.
 The structure of gas-liquid processor, whose process is simple, is frame combined, making the installation, operation and maintenance easier.
 The silicon rectifier is adopted to replace the original silicon controlled rectifier, which can reduce the harmonic interference to the power grid, effectively eliminating the high-order harmonic pollution to the power grid, and reducing the reactive power loss.
 Controlled by highly automatic microcomputer, the system is able to do remote centralized management. Human-machine intelligent interface makes the operation easy, safe and reliable.
 The purity of the hydrogen generated can reach to 99.99%, Oxygen 99.2%
