Switch cabinets

In order to operate the KLARO One UP clarification technology, the proven KLARO switch cabinet technology is also used here.

Small Nitto compressors are installed due to the low wastewater volumes.
This makes the compact PP indoor cabinet the perfect complement to the KLARO One UP.
Alternatively, the system is installed with a metal indoor cabinet or a PP outdoor cabinet.
