Our electrolysis module EOM is also designed as a 19-inch plug-in module. Core of the electrolysis module is the S30-x stack from H-TEC Systems. We have added all the necessary components to the core to create a functional and safe electrolysis module.
The electrolysis module can be equipped with the S30-10, S30-30 or S30-50 stack

Water purification module EWM
Very pure water is necessary for the operation of the electrolysis. For this reason, we prepare the water in our EWM water purification module directly on site. The customer only needs a water connection with tap water of drinking water quality.
The water is treated using standard ion exchangers. Depending on the existing water quality (water hardness), these must be replaced at shorter or longer intervals. An appropriate measuring technique informs the customer in time about an upcoming exchange of the ion exchange resin.
The water purification module is designed as a 19“ rack.

Electrolysis power module ESM
The electrolysis module must be supplied with electricity to produce hydrogen. For this purpose we use a robust industrial power supply unit in 19‘‘ standard format.
Depending on the existing situation on site you can choose between an AC/DC power supply with 400 VAC three-phase connection or a DC/DC power supply with 48 VDC connection.
Across the electrolysis 3 voltage levels are currently used: 400 VAC, 230 VAC and 24 VDC

Electrolysis frame module ERM
Our electrolysis frame module is the platform in which all other modules can be mounted. The electrolysis frame module is available with one or two compartments for 19-inch racks. In the standard version it is equipped with stands and powder-coated in light grey. Other RAL colors, castors and doors with acrylic glass panels are optionally available.
If a mounting platform in 19-inch format is already available, the modules can of course also be integrated into the existing structure.
