Reduce running costs in telecom cooling and save up to 250W per hour*

BD250GH.2/BD350GH with 48 V DC for telecommunication battery cooling.

In areas relying on battery power for up to 16 hours a day, be ensured that BD compressors will ever cool your battery at 25°C and thus optimise their life lasting. Secure your signal and save your maintenance and replacement costs.

Battery drain being a big issue, BD compressors will allow you to:

  • Use an energy efficient direct current (DC) compressor with a high COP.
  • Build a cooling system that can run on batteries, solar cells and wind turbines without needing conversion to alternating current (AC).
  • Simplify the design of the overall system and ensure maximum performance.

*Compared to other solutions that rely on AC and 230 V AC conversion.
