General information about your application?

The EFOY Pro fuel cells are empowering the monitoring of mines and open pit mines. The monitoring systems are based on GNSS satellite navigation or optical encoders that capture and send readings in combination with PC and radio modems. The duration varies between 0.5 and 2 years.

Which energy problems or challenges were did you have to address?

Significant was to ensure a continuous power supply for our monitoring systems. Until the use of fuel cells the power supply had to be connected via cable to grid. This meant a very high effort to have power available on the site.

The solution:
EFOY Pro fuel cells

Two EFOY Pros in hybrid operation with solar cells in use.

“EFOY Pro convinced”

During a test phase, which was realized by the university, an EFOY Pro was used. Both, the performance parameters as well as the handling convinced.

Mr Frank Hoffmann, Vattenfall Europe Mining AG

How is the EFOY Pro integrated in your installation?

The EFOY Pro fuel cells are housed in aluminum boxes. These boxes contain all necessary technical systems for the operation to the monitoring station (inverter, solar converters, PC, wireless modem, etc.).

How many EFOYs do you use and do you also combine other alternative power sources?

At the moment there are two EFOY Pros in hybrid operation with solar cells in use.

What are the benefits of EFOY in your application?

The use of the monitoring systems is now much more flexible and is not tied to direct power anymore. This enables faster response times an increased the security.
