O
2
VENT:
The O
2
vent outlet is a push-fit bulkhead, with an outside diameter of 10mm. This outlet port
is directly connected to the electrolyte tank, and its primary function is to evacuate the produced
Oxygen. Apart from that, a small quantity of Hydrogen (less than 2%) and up to 25 mL/h of water is
produced.
If multiple electrolysers are connected together, a KOH resistant check valve must be
connected directly to the "O
2
VENT" port with a maximum cracking pressure of 0.02 barg to to avoid
the vent output from one electrolyser to enter another electrolyser
. Follow the below instructions
carefully
–
please refer to the manufacturers technical support guide for any further details:
Tools required
The following tools and materials are required for this task:
•
Plastic tube cutter
•
Push-fit locking clips (10 mm)
•
10 mm diameter LDPE tubing
Ensure the tubing chosen for this task is pressure-resistant to at least 0.5 barg!
10 mm KOH resistant Check valve for vent line (max crack pressure of 0,02 barg), only in case
of multiple Electrolysers are connected in parallel.
Instructions
1.
Cut the tube square and remove sharp edges. Ensure the outside diameter is free of score
marks, and the cut is perpendicular across the tube. Fully insert the tube into the fitting. The
inserted pipe diameter must be 10 mm Ø. As mentioned previously, this line will have oxygen
in its majority, with a small percentage of hydrogen (less than 2%) and a production of around
25 ml/h of water vapor, which depending on external environmental conditions will condense
inside the line, so it must have a suitable container to retain and drain this water in compliance
with local and national regulations. The
"O
2
VENT"
line must be led to an external safety area.
In case multiple Electrolysers are connected together in parallel, insert a small piece of 10 mm
Ø tube and immediately place the check valve as close as possible from the vent outlet, then
continue with the steps previously explained.
2.
Pull the tube to check it is firmly held in place, then secure the connection by inserting a red
10mm fastening clip.
3.
To disconnect, push the collet against the fitting, while simultaneously pushing the tube into
the fitting. Holding the collet in this position pull the tube out of the fitting in one smooth
motion.
