For softening or partial softening of drinking water in multi-family houses,
housing areas, hospitals, and service water, process water, boiler feed
water, cooling water and air conditioning water and for reducing malfunctions
and damage due to lime in water pipes and connected water-carrying system
components.

Rondomat Duo is a duplex softening unit which functions in accordance with
the ion exchange principle. The unit is run with columns continually changed
at short intervals. This method of operating ensures that softened water is
even available during a regeneration procedure, while the frequent column
change minimises stagnation times. In terms of chemical and microbiological
parameters, this leads to significantly better water quality than with
conventional alternating softening units.
Regeneration is triggered volumetrically (depends on the quantity of water).
Very brief salt dilution times and short regeneration periods are achieved as
a result of a salt hopper for storing and dissolving salt and a new quick-filling
system for the brine container (patent pending).
The hardness of local untreated water is entered into the electronic system
when the unit is started. All other unit parameters are stored in the electronic
system. All unit data is preset and unit parameters can be queried. The
remaining capacity is displayed in liters or in bar-graph form. The flow quantity
is displayed in l/h during operation.

device that disinfects the ion exchanger during the regeneration process.
Spring-loaded non-return valves protect all connections on the upstream
side of the unit. This eliminates the need for a system or a pipe isolator.
