H2 D-lyzer
DC/DC CONVERTER TO FEED ELECTROLYSERS DIRECTLY FROM A SOLAR PV PLANT
Enabling green hydrogen production
INGECON® H2 D-lyzer enables a true green hydrogen production, as it has been conceived to feed the electrolyser with solar
energy.
DC/DC converter
INGECON® H2 D-lyzer is a DC/DC converter with a DC input for the solar PV array and a DC output that connects directly to
the electrolyser.
Liquid Cooling System (LCS)
The LCS is a closed circuit supplied totally filled and purged, equipped with fast connectors with an anti-dripping system, so it
offers zero risk of particle entrance. It has been designed to avoid siphons in order to easily purge it if necessary. The coolant
used is a biodegradable glycol water mixture. There is no need of emptying the LCS in order to replace the phases, nor the
sensors.
Ease of maintenance
All the elements can be removed or replaced directly from the converter’s front and back sides, thanks to its new design.
Buck converter
The INGECON® H2 D-lyzer is a buck converter, as the output voltage is lower than the input voltage.
