Hydrogen must be dried after electrolysis because, in addition to hydrogen, moisture is also produced during electrolysis and pure hydrogen is required for many applications.
Industry/Application:
Construction and operation of adsorption dryers
Medium:
Moist hydrogen, pressure up to 46 bar (g), temperatures from -10°C to +180°C
Task:
Tightness inside (absolutely leak-proof)
Tightness outside (technically permanently tight)
Resistance to hydrogen embrittlement
Easy maintenance
Our solution / applied valve
