ENAPTER ELECTROLYSER SYSTEMS

ENAPTER ELECTROLYSERS ARE THE PORTAL TO THE HYDROGEN ECONOMY

Our AEM electrolysers are the most cost-effective and high performance solution for hydrogen production ranging from 0.5Nm3/hr to 10Nm3/hr.

FLEXIBLE • SCALABLE • FAST TO DEPLOY

EL 2.0 Key Features • 500 NL/hr or 0.5 Nm3/hr hydrogen output • Stackable to form larger electrolyser systems • Output pressure up to 35 bar • Hydrogen purity 99.95%, 99.999% with optional dryer module

3 • High efficiency (4.8 kWh for 1 Nm of H2 at system level) • Rack-mountable in standard 19” cabinet • Native operation with Enapter EMS (remote monitoring and control system) • Simple installation and low maintenance • Low requirements for input water purity

Up to four EL 2.0 modules and one optional dryer can be combined in a single 19” cabinet by Enapter or a qualified system integration partner. Please see next page for more details on the optional modules offered by Enapter. EL 2.0 Data Sheet

Enapter Water Supply System Components

Water Purification Module (WPM) Water Tank

An optional 40L clean water Input water tap / rain water tank can be integrated into the cabinet. Output water <20 µS/cm Operative power It can be filled by the WMP or 200 W (20W standby) consumption other clean water supply and includes a pumping system Typical flow rate 0.2-0.4L/min to supply the electrolysers.

Mounted on sidewall of caninet or other wall surface Size in cabinet: 8U.

Enapter’s water supply system is completely optional and our customers are welcome to use any water supply system to EL that meets the specifications (<20 µS/cm).
