Acid cleaning station
4.12 Gas warning system
As a part of the safety concept, a gas warning system for
hydrogen gas (H
2
) must be installed at the installation location.
The Selcoperm electrolyser provides a two-channel safety input
to shut down the whole system in case of gas leakage.
5. Technical data
5.1 Selcoperm Electrolysis System (SES)
The following data apply to the core components of the
Selcoperm electrolysis system and cover all capacity levels.
5.1.1 Water quality specification
Make sure that the water supply conforms to the required
standard of drinking water given in the specification below. Ask
your local water supplier for the specific values.
5.1.2 Salt specification
Use food-grade granular/pellet salt (98.5 % NaCl) according to
EN 14805 type 2 with following minimum requirements:
5.1.3 Ambient conditions
* System must be drained. For storage temperatures below +5
°C, the whole system including water softener, lines and
external components must not contain any water.

Exposition to direct sunlight can cause colour
changes, material deformations and cracks.
Do not expose the system to direct sunlight.
Because of the embrittlement of plastics at low
temperatures, the transport must not be done if the
temperature falls below the specified value for
transport, otherwise plastic parts can be damaged.
Freezing and boiling liquids can cause damage.
Observe the freezing and boiling points of the used
liquids. The freezing and boiling point of a liquid
varies depending on the pressure.
