The BCU provides the cooling and purging processes.
The variable air/gas ratio control compensates for gas/
air pressure fluctuations. Optional: the pressure switch
monitors the air flow during pre-purge and operation.
The gas/air mixture is adjusted to the requirements of
the application using the parameters of pre-ventilation
and post-ventilation.
