Mixed-bed full demineralization unit
Stand unit for producing water which is equivalent
to destilled water. With attached electrical
conductance meter (0...20 mS). Including a
cartridge which may be regenerated. When the
conductance meter indicates a conductance of
over 20 mS the cartridge will have to be
returned to the manufacturer for the regeneration
(shipping documents are enclosed). In
order to ensure a continuous supply of highpurity
water the purchase of a further exchange
cartridge (> 666 904) is recommended.
Complete with 1.5 m long hose and R 3/4” fitting
for immediate connection to the water
supply, with mains cable and mains plug.

Water distillation unit
Fully automatic unit with solenoid valve for
production of distilled water which is free of
germs and pyrogens. Conductivity of the
produced water is about 2.3 uS at 20 °C. All
parts which come into contact with water or
water vapour are made of stainless steel. The
built-in elec-tronic level switch shuts off the
supply to the heater and also interrupts the
cooling water and the feed water supply as
soon as the reservoir vessel is full. When
drawing distilled water the unit comes on again
automatically. with protection against low water
(overtemperature switch), to prevent the heater
from overheating.
The unit also switches itself off automatically
in case the distillation section becomes
contaminated.
May be used either as a table-top unit,
or for wall mounting.
Feed water line: 11 mm dia.
Water drain: 12 mm dia.
Distillate supply line:
cock at the front of the lower section
Capacity: 4 l/h
Reservoir vessel: 8 l
Cooling water consumption: 48 l/h
Power supply: 230 V/50 Hz; 3 kW
Dimensions: 620 x 330 x 460 mm
Weight: 20.2 kg
