Enapter makes dierent versions of
electrolyser based on your needs.
Electrolysers come in AC/D
or DC/DC versions as well as air-
cooled or liquid-cooled versions.

3 W ater Inlet R e q uirements
H2 O I N port is used for automac re  lling from connected
demineralised water source during normal operaon ,  rst re  lling
and maintenance. During hydrogen producon water consumpon
rate is around 4 00 m L /hr.
U se Enapter W ater T ank to solve the problem of
unstable water supply It can be  lled manually with
prepared demineralised water as well as directly
connected to water source.
Enapter W ater tank deliveries pressure up to 2. 75 bar.
W ater conducvity must be < 20 µ S/cm ( at 2 5° C ) .
С onnect electrolyser to water supply
only through water purification
system. W ater conductivity must be
< 20 µ S/cm ( at 2 5° C ) and pressure
between of 1- 4 bar.
H2 O I N
P roper inlet water source must be connected before
proceeding to the next steps
Flush all water pipes with demineralised water before
connecng your device to ensure nothing is stuck in the lines
4 Check H2 V ent and O 2 V ent Lines
It is the installer ' s responsibility to regularly check and maintai 
H2 V E NT and O 2 V E NT lines , as well as keeping the lines free of ice
and any obstrucons.
Do not insert any check valves
or obstrucons into th 
H2 V E NT lines. T his can cause
irreparable damage to your
hydrogen system.
H2 V E NT
O 2 V E NT
N o blockage should be present
on O 2 V E NT on the user side of
the interface.
DO N O T connect H2 V E NT line with O 2 V E NT line
Mixing these outputs is extremely dangerous
Alternang current voltage of 22 0- 2 40 V is potenally lethal !
Direct current voltage of 4 8 - 6 0 V can be a ha z ard !
A valid safety concept must be in place U sually this involves
compliance with operang environment condions , su  cient
venlaon and / or hydrogen detecon systems at the
installaon site For more details , please consult the user
manual or contact Enapter
Always check H2 vent and O 2 vent lines for blockage and
damage
