PERFECT PURE SENSOR
Residues in the wash liquor can compro-
mise thorough cleaning. Likewise, residual
alkali in the rinse solution, for example from
ophthalmic instruments, can lead to unde-
sirable side effects next time the machine
is used. In the new PG 85 series machines
the conductivity level of the wash liquor is
measured and monitored by electro-mag-
netic impulses in a maintenance-free sys-
tem. This unique process works with ex-
tremely narrow tolerances in a range of
0–40 µS/cm and 0.4–100 mS/cm. If the
conductivity level pre-defined by the user
is not reached in the final rinse, further
rinses are automatically carried out.
PERFECT FLOW SENSOR
The current standard DIN EN ISO 15883
stipulates that the dispensing of liquid
media should be independently monitored.
The new dispensing volume control from
Miele, PERFECT FLOW SENSOR, offers far
greater reliability than traditional measuring
systems. The measuring system is includ-
ed as standard and allows very precise
control of the dosage. Dosage tolerances
can be defined by the user. The system
works by ultrasound and, in contrast to
most measuring systems with flow wheels,
is not affected by temperature or viscosity.
If tolerances are exceeded an error mes-
sage is displayed or the programme is ter-
minated.
PERFECT HEPA DRYING
Miele is also setting new hygiene standards
for the drying phase. A class EU 13 HEPA
high temperature filter in the front of the
wash cabinet prevents undesirable particles
from entering the heater, fan or silencer, so
the air in the wash cabinet is exceptionally
clean. This has the added benefit of ex-
tending service intervals.
Reliability, efficiency and hygiene –
Perfect Miele
The results can be shown in the display
and subsequently documented. Recording
the conductivity level throughout the
process offers another opportunity to verify
the exact replication of the validated
process.
