Integrated-type H2 generator
One of the most compact units on the market, the integrated hydrogen generator is specially designed for the electrical power industry.
Integrated systems are standardized and modular and can be controlled individually or clustered. The single hydrogen electrolyzer, gas-lye treater and H2 purification unit are built in one unit and have production flows ranging from 5Nm³/h to 15Nm³/h with an operating pressure of 15 bar. The H2 purity is higher than 99.999% and dew point higher than -60 Deg.C.
This integrated hydrogen generator becomes more convenient to customers for installation, operation, and maintenance, and reduces capital costs associated with civil construction.
Fully automatic control and connection with the customer’s DCS system for monitoring is possible.
