The hydrogen purification unit adopt two (three) dryers to work in turn and feed gas regeneration mode according to the needs of users. The pneumatic valve in the device is controlled by PLC program, which can realize the automatic switching of the working state of the dryer,it has the function of automatic drainage. The hydrogen purity of the product is 99.999%, the oxygen content is less than or equal to 1ppm, and the water content less than or equal to 1ppm (dew point is less than -70 ℃)

Xiamen Zhongxinda Hydrogen Technology Co., Ltd. has been specialized in the design, R & D, manufacture and sales of water electrolysis hydrogen production equipment, hydrogen storage equipment, hydrogen bus bar and hydrogen purification device in various industries for many years.

The hydrogen production capacity of the equipment produced by our company ranges from 2 m3/h to 1500m3/h.The hydrogen energy equipment of by-product hydrogen tail gas, peak shaving and frequency regulation of thermal power plant provide the design, production, installation and commissioning of hydrogen production, hydrogen storage, hydrogen production and hydrogenation station and technical services.

We have a professional after-sales service team for hydrogen generation system with rich experience in hydrogen machine maintenance.According to the running state and environment of hydrogen production machine , we will help you optimize and upgrade the system, design plans suitable for the operation of the machine, improve the monitoring and detection for DCS and PLC, enhance the running safety and using cycle of hydrogen production equipment, so that reduce system failure caused by peripheral equipment (hydrogen compressor, dryer, PLC controller, etc.) and equipment failure or accident caused by personnel operation mistakes.

In view of the system shutdown caused by the fault of individual components for most users (such as system pressure imbalance and inaccurate measurement of the analyzer caused by the fault of pressure transmitter and ), we have stable detection methods and equipment maintenance plans for hydrogen production machine.
