1. General information
1.1 Documentation package
The documentation delivered with the Selcoperm electrolysis
system comprises:
• Installation and operating instructions for Selcoperm
• Separate supplier manuals for built-in components
• Wiring diagrams (in control cabinets).
The complete documentation package must be available at the
installation location at all times.
1.2 Scope of this document
The Selcoperm electrolysis system comprises a number of
components. The core components must be purchased from
Grundfos to ensure the compliance with the Selcoperm safety
concept. These core components are:
• Selcoperm electrolyser
• Rectifier
• Brine dosing station
• Degassing and storage tank with a special installation set
including the degassing fan
• Acid cleaning station.
The Selcoperm safety concept requires a gas warning system for
hydrogen, which must meet specific requirements.
Further components required for the system are:
• Water softener
• Brine tank.
In addition, a chiller or heater can be required to achieve the
specified water inlet temperature. All mentioned components can
be purchased from Grundfos. For details see section
4.1.4 Overview of components .
This document contains detailed information on the core
components and their installation, and on general requirements
for additional components and their installation. The requirements
for components and their installation described in this document
must be adhered to, no matter if the components were purchased
from Grundfos or not. The documentation package delivered with
the Selcoperm system contains additional documents for
components, which must be observed.
