Our compact CHP units can be equipped to run in island operation, meaning that they can provide a power busbar with defined consumers (e.g. elevators, sprinklers, pumps, IT system, lighting etc.) with emergency power in case of a mains failure or blackout.
If the CHP unit is idle when the mains failure occurs, it starts automatically with the battery unit and supplies the emergency busbar in several loadsteps. The full load is available after ca. 30 seconds.
If the CHP unit is already running in mains parallel operation it automatically separates from the mains and seamlessly starts to supply the emergency busbar. After the mains returns, it seamlessly switches to mains parallel operation or – if e.g. no CHP heat is needed – starts the CHP shutdown process.
To provide this emergency power option also in times with no (or too little) heat demand, an emergency cooler must be installed. Also multiple CHP unit schemes can be equipped with emergency power function: Our largest emergency power scheme contains four CHP units with 1,6 MW of electric power in total.
