Tunze RO Water Controller 8555
The Tunze RO Water Controller 8555 is an automatic top off system to control the production of RODI water. It comes with 2 float switches, a water control solenoid valve and a 12 volt power supply. The solenoid valve connects the RODI outlet to the reservoir so that the unit can function. When the water level is below your first float valve, it will start filling your reservoir with RODI water and stops when it is above your second float valve.

The controller is also suitable for other water tanks or can be connected to an automatic refill system. It consists of a controller, two sensors, a water valve and an 12 V power supply unit. Depending on the use, the water valve can be replaced by switched socket outlet 3150.110 for mains operation.
If the position of the sensors of the RO water controller is reversed, the switched socket outlet 3150.110 and a pump can be used to empty a water tank, and thus it can also be used for automatic filling or emptying of tanks. By means of a combination of two units, a water changing system can be built.
