Smart Sustainable Utility Unit RAIN

This never-before-seen utility unit has two functions. Sustainable climate control of a whole building and smart power management. Energy is generated from sun energy and/or windenergy with a generator as back-up or taken from a local electric power network. In this way a building can run autonomously, no matter where.


  • Inverter (battery charger and converter to 3 x 400VAC)
  • Battery specification: light weight, 6.2 kWh 240A/IC Nominal charge, IP 65
  • Unique BMS with Advanced Active Cell Balancing
  • Generator 40 kW
  • Fully integrated ventilation unit is able to cool ventilation air indirectly on an adiabatic base
  • Ventilation air is maximum 4400 m³/h and recirculation is 8800 m³/h
  • Wintertime: the adiabatic cooler is a heat exchanger to exchange warmth from the ventilation air
  • Power of the heatpump in cooling stage 60 kW, in heating stage 55 kW
