2. Safety instructions
Non-observance of the safety instructions may have dangerous
consequences for persons, the environment and the product.
2.1 Working with chemicals
2.1.1 Personal protective equipment
Due to the variety of hazardous chemicals, any information
provided in this section is only general. We recommend to follow
good practice when handling chemicals, to use personal
protective equipment such as ventilated, enclosed goggles, face
shields, chemical aprons, boots and gloves, and to install an eye
shower.
2.1.2 Sodium hypochlorite solution
The concentration of the sodium hypochlorite (NaClO) solution
produced by the Selcoperm electrolysis system is below 1 %.
• If splashed onto skin, wash off with fresh water. Remove all
affected clothing.
• If the eyes are affected, rinse them immediately using an
approved eye shower or fresh running water for at least 15
minutes, keeping the eyelid open and rotating the eye. Seek
medical treatment immediately.
• If swallowed, do not induce vomiting. Keep the patient warm
and quiet and seek immediate medical help. If the patient
stops breathing, apply rescue breaths and cardiopulmonary
resuscitation as necessary, until medical help arrives.
Warning notices advising users of the possible dangers should be
prominently displayed wherever sodium hypochlorite is stored,
generated or handled.
2.1.3 Hydrogen gas
The electrolytic process of converting brine into sodium
hypochlorite (NaClO) solution generates hydrogen gas, which is
diluted and lead to a safe external discharge point by means of
forced ventilation. The degassing and storage tank as well as all
vent piping should be regularly checked to ensure that no gas
leakages occur.
Hydrogen is an explosive gas and lighter than air. When liberated
in a room, hydrogen accumulates beneath the ceiling. Ensure
natural ventilation at a high and a low level in the room where the
electrolyser is installed.
A sign that prohibits smoking and naked flames must be
displayed in the room and at the point of discharge to the exterior.
A gas warning system for hydrogen must be installed at the
installation location to stop the Selcoperm electrolysis system in
case of a build-up of hydrogen gas. This avoids the situation of a
user working in a potentially explosive environment.
This symbol indicates a danger of electric shock.
This symbol indicates a potentially explosive
atmosphere (ATEX zone).
This symbol indicates explosion-proof products.

4.1.5 Safety concept
This section refers to fig. 2.
A reliable safety concept for the operation of the whole system is
mandatory, because hydrogen is produced as a by-product in the
electrolysis cells.
Before even entering the degassing and storage tank (G), most of
the hydrogen is diluted by the degassing fan to 25 % of the lower
explosive limit (LEL) and led away into the atmosphere. In the
tank, the residual hydrogen is released, diluted and led away into
the atmosphere.
The whole Selcoperm electrolysis system is monitored
permanently and redundantly. Several sensors at the system,
together with hydrogen sensors at the installation location ensure
a safety shutdown of the whole system in the event of a failure.
Small amounts of hydrogen, which can escape due to a leakage,
are led away via the ventilation hole (I) at the highest point of the
room.
The safety concept is evaluated with technical report by a
third-party expert from TÜV SÜD Product Service GmbH. It
ensures safe operation without any additional explosion
protection at the installation location.
Hydrogen (H

) characteristics
Conformity with ATEX directive
The ATEX directive covers devices that can be used in a
potentially explosive atmosphere and/or may contain a potentially
explosive atmosphere. However, the ATEX directive is only
applicable, if the device has a potential source of ignition in its
internal zoned area.
The Selcoperm system has internal zoned areas, but the ignition
sources inside the system have been eliminated by design. The
Selcoperm system is not intended for operation in a potentially
explosive atmosphere. Therefore, the Selcoperm system is not
subject to the ATEX directive and must not be ATEX marked. A
declaration of conformity in accordance with the directive is not
applicable.
The following guidelines and standards have been applied:
• Machinery Directive 2006/42/EC
• EN ISO 12100 for the risk analysis
• DIN EN 1127-1 and DIN EN 13463-1 for the identification of
explosion hazards and ignition sources
• (EX-RL) BGR 104, TRBS2152 and DIN EN 60079-10-1 for
zoning and security measures
Furthermore, the explosion safety is ensured by several
measures.
Explosion protection by avoiding the explosive zones:
• Preventing or limiting inside the unit
– Redundant level sensors to ensure liquid filled parts
• Preventing or limiting to the facility
– All connections are designed as permanently technically
sealed according to DIN EN 1127-1:2011 Appendix B and
TRBS 2152 Part2 2.4.3
– Design with flange, glue or weld connection
– Organisational measures by 100 % FAT leakage test,
leakage sensors and permanently monitoring of H
2
leakage
by H
2
sensors and safe shutdown
• Reduction of the zones through ventilation
– Exhaust gas is diluted with air down to 1 % by volume.
Correct air flow is monitored redundantly and leads to safe
shutdown in case of failure.
Explosion Protection by avoiding ignition sources
• An ignition source analysis and earthing concept was carried
out for the system. All ignition sources inside the system were
eliminated by design. During operation, cells and piping of the
system are filled with liquid. No electrical or moving
mechanical components are implemented. Sensors that affect
an explosive area are used as ATEX sensor.
Safety Facts
• Unique safety concept, evaluated with technical report by a
third-party expert from TÜV SÜD Product Service GmbH
• Technically permanently sealed components and thus no zone
in the installation room
• Ignition sources inside the system eliminated by design
• Artificial ventilation to dilute H
2
by-product inside the system
– Redundant monitoring of the ventilation system (fan & flow)
– Pressureless system; no valves after the cells; dangerous
pressure build-up is impossible.
– High quality standard: Every Selcoperm electrolyser is
checked for 100 % performance and tightness at the factory
– Direct pipe-to-product degassing tank with level switches
(cell outlet & tank inlet) to ensure filled lines and electrode
fluid level. No gas accumulation.
– Alarm and safe automatic shutdown of the installation in
case of an error, e.g. drop of flow for dilution
– Redundant safety including a gas detection system
combined with ventilation inside the building
Acceptance test by TÜV is possible for a complete system
installed on site.

Labelling recommendations
A warning sign must be placed on the outside of the degassing
and storage tank near the manhole. The purpose of the sign is to
warn people of an explosive atmosphere, so that they can take
the necessary precautions.
We recommend that the sign is accompanied by a written notice,
e.g. "Permanently technically sealed system, during process
zone 2 inside, outside no external zones".
Fig. 3 Label for degassing and storage tank
An additional sign must be placed near the exhaust air outlet of
the building to inform people of the zone radius.

4.1.7 Process description
This section refers to fig. 5.
General information
The number of electrolysis cells in a Selcoperm electrolyser
depends on the SES type:
Figure 5 shows the PID of the largest system which includes an
electrolyser type SES-45000 with 6 electrolysis cells. The
functional principal described here also applies to smaller
systems with less electrolysis cells.
The soft water for the Selcoperm electrolyser is connected to soft
water inlet (A). The soft water enters the system via shut-off valve
(V0.01) and passes through pressure reducing valve (V0.02) to
ensure a regulated pressure in the system.
The brine supplied by brine dosing station (BDS) is connected to
brine inlet (B) and passes shut-off valve (V0.10). The brine dosing
station (BDS) is usually equipped with 2 brine pumps (DP0.10)
and (DP0.11). Only 1 brine pump is used for production while the
other pump is in standby mode. The system can be configured to
alternate between the 2 pumps each time production is started or
in case the used pump fails. For simplification the following
description only refers to brine pump (DP0.10).
The degassing and storage tank (DST) can optionally be
equipped with a second standby degassing fan (EF4.02). The
system can be configured to alternate between the 2 degassing
fans each time production is started or in case the used fan fails.
For simplification the following description only refers to
degassing fan (EF4.01), which is included in each system as a
standard.
Production process
When the system starts production, degassing fan (EF4.01) on
degassing and storage tank (E4.05) is switched on. Once the
exhaust air flow sensor (4.13) measures the correct flow rate,
solenoid valve (0.05) opens and brine pump (DP0.10) is started.
The soft water passes flow sensor (0.02) and is mixed with the
brine in static mixer (V0.05). The resulting electrolyte passes flow
sensors (1.10, 2.10, 3.10) and adjusting valves (V1.01, V2.01,
V3.01) before it enters the electrolysis cells via 3-way valves
(V1.02, V2.02, V3.02). The level switches (1.09, 2.09, 3.09)
signal to the PLC that the electrolysis cells are filled. As soon as
level switch (4.04) signals to the PLC that the NaClO (sodium
hypochlorite) solution line is filled, the rectifier (REC) switches on
the DC power supply for the cells (C1.1, C1.2, C2.1, C2.2, C3.1,
C3.2) to start the electrolysis. The temperature switches (1.01 -
1.04, 2.01 - 2.04, 3.01 - 3.04) monitor the temperature of the DC
connections on the cells.
The temperature sensor (0.03) monitors the temperature of the
NaClO solution before it passes outlet (V). The NaClO solution
contains a certain amount of hydrogen gas, which is produced as
a by-product in electrolysis. It is led through a horizontal or
slightly upwards inclining line into the degassing and storage tank
(E4.05). Before entering the tank, the NaClO solution passes the
T-piece (TP) to separate the hydrogen gas. The separated
hydrogen gas is immediately diluted with air from degassing fan
(EF4.01) to 25 % of the LEL. The exhaust air is led away through
exhaust air outlet (T) to a safe external discharge point. The
correct air flow in the exhaust air line is monitored by air flow
sensor (4.13). In addition, the frequency converter of the
degassing fan is used to monitor the fan speed.
When the NaClO solution reaches the stop-fill level in the tank
measured by level sensor (4.10), the process is stopped. First,
the DC power supply from the rectifier (REC) to the electrolysis
cells is switched off. Solenoid valve (0.05) stays open, and brine
pump (DP0.10) keeps running to flush the lines and cells with
electrolyte for a few minutes.
After flushing is completed, brine pump (DP0.10) stops and
solenoid valve (0.05) closes. The flow of electrolyte through the
electrolysis cells stops. The degassing fan (EF4.01) stops after a
few minutes. The system switches into "Standby" mode.
Additional monitoring equipment
The gas warning system (H2S) with two hydrogen sensors (5.01,
5.02) measures the concentration of hydrogen at the installation
location. If hydrogen is detected, the gas warning controller (5.00)
sends a signal to the PLC in the control cabinet (CTR) of the
Selcoperm electrolyser to shut down the system.
The level switch (0.01) detects liquid in the Selcoperm
electrolyser housing.
The level switch (4.03) detects liquid in the collecting tray of tank
(E4.05).
Dosing of produced NaClO solution
The NaClO solution can be dosed directly from tank (E4.05) via
solution outlet (U) to the point of application. It is also possible to
pump the NaClO solution from tank (E4.05) into separate storage
tanks.
Sampling
A sample of the NaClO solution can be taken from sample outlet
(X) via sample valve (V0.09). A sample of the electrolyte entering
the electrolysis cells can be taken at sample outlet (Y) via sample
valve (V0.06).
Draining
After the system has been flushed and switched off, it can be
drained via drain outlet (Z) using drain outlet valve (V0.08) and
3-way valves (V1.02, V2.02, V3.02).
Acid cleaning
For acid cleaning of the electrodes within the electrolysis cells, an
external acid cleaning station can be connected to (C). Acid
cleaning must be done according to section 9.5 Acid cleaning.
Operation and supervision
All components and safety functions are monitored and operated
via a multi-colour touchscreen on the Selcoperm electrolyser
(SES). If a fault occurs, the system stops and a message is
displayed on the touchscreen.
