Energy efficiency thanks to
DC inverter technology

Future-proof climate control.

  • Active cooling circuit with speed-regulated components for demand-based cooling
  • High control accuracy thanks to needs-based DC inverter technology with two regulating modes

Eco-friendly.

  • 55% less refrigerant as a result of using microchannel technology

Transparent efficiency comparison.

  • Energy Efficiency Ratio (EER) –
    the standard-compliant efficiency value
  • Seasonal Energy Performance Ratio –
    the power-specific efficiency value for actual annual energy consumption
