Water of constant high quality!
• Automatic circulation of water in
the tank through an additional
PurMaxx pure water module plus
free cycle setting
• Ensures maintenance of the
permanently low conductivity even
for long periods of inactivity
Assured highest hygiene!
• Optional UV lamp in the tank
recirculation system reduces
organic constituents – optional
sterile filter for tank water outlet
A flexible future!
• MaxiTower Plus can grow to
match increased requirements.
The performance can be upgraded
from a flow rate of 80 to 0,
for example, by a simple module
enlargement. And it is just as easy
to replace a small tank by a larger
one.

Comfortable operation!
Clear information!
The large -line display is code
protected and offers a choice of
three languages, English, German or
French. It is illuminated , easy to
read and provides information on:
• the temperature in °C
• the temperature-compensated conductivity
of water coming from the
osmosis/high purity polisher module
• the operating mode status, such as
production, stand-by, rinsing
• the tank content in %
• the RS interface
• the fault memory function
Easy to work with!
Just six control keys allow for rapid
operational readiness
• Start/stop of high purity water
production
• Start/stop of other operating
sequencies and service procedures
• Limiting values settings, conductivity
RO water and high purity water
• Recirculation interval
• On/off of the optional UV lamp
Tank level control indicator!
Continual monitoring of the tank
volume in %.
Designed for Qualification!
TKA MaxiTower plus has been
designed to fulfill GLP requirements.
Recording and traceability of data
are ensured via an RS interface
and a TKA printer. A cell constant of
0.01 cm -1 guarantees highly qualified
and precise measurement of the
conductivity, which is compensated
to an accuracy of ± 0.1 °C (acc. to USP
) even with only minimal temperature
change.
A good view!
Just set the tiltable display/keypad
unit to the best viewing/operating
position for you.

Combination of
electrodialysis and
ion exchange
processes
Electrodeionisation, EDI in brief, unites
two proven technologies for producing
ultrapure water: Electrodialysis and
ion exchange (IEX). The great technical
thing about this: In contrast to conventional
ion exchange, in which resins
must be chemically regenerated, EDI
utilizes an electric current for continual
resin regeneration.

How EDI works
Several layers of ion selective membranes
are situated between an anode
and a cathode. Layered ion exchanger
resin beds and concentrate chambers
are alternately positioned between
them.
On applying an electric voltage, water
(H 0) is split into H + and OH – in the cell.
The H + and Na + cations can migrate
through the cation permeable membranes,
anions through the anion permeable
membranes.
The ions migrate in the direction of
the applied voltage, i.e. anions to the
positive pole (anode), cations to the

negative pole (cathode). The water
ions H + and OH – that migrate through
an ion exchange chamber displace salt
ions retained by the ion exchanger resins
and so continually regenerate the
resins.
The salt ions migrate through the
appropriate ion selective membranes
into the concentrate chambers and are
flushed out of them by water. As all
concentration chambers are flushed
through one after the other, excess H +
and OH – ions can again combine to
form H 0.

The best water
pretreatment!
TKA MixMulti XL
This system can be used even when the
feedwater condition is very difficult.
It not only softens the water but also
efficiently cleans it and so protects the
osmosis membranes from blockage. In
addition to calcium and magnesium,
it also removes iron and manganese, a
great variety of suspended matter and
organic material. The secret lies in the
combination of multiple adsorption
stages, from porous polymeric adsorbers
to ion exchangers.
MixMulti can be regenerated exactly
as a normal water softener, i.e. with a
conventional saturated sodium chloride
solution (8–10%).
