Process chemicals
Efficacy
Measures
The ingredients in process chemicals have
a strong influence on the longevity and
functionality (throughput) of the dispensing
system.
- Follow the process chemical
manufacturer’s instructions and
recommendations.
- Carry out a regular visual check of the
dispensing system (suction lances, hoses,
dispenser canisters, etc.) for any damage.
- Regularly check the flow rate of the
dispensing system.
- Ensure that the regular cycle of
maintenance is observed.
- Please contact Miele for advice.
Process chemicals can damage elastomers
and plastics in the cleaning machine and
accessories.
- Follow the process chemical
manufacturer’s instructions and
recommendations.
- Carry out a regular visual check of any
accessible elastomers and plastics for
damage.
The following process chemicals can cause
large amounts of foam to build up:
- Cleaning agents and rinsing agents
containing surfactants
Foam can occur:
- In the programme block in which the
process chemical is dispensed
- In the following programme block if it has
been spilt
- In the following programme with rinsing
agent if it has been spilt
- The process parameters in the wash
programme, such as dispensing
temperature, dosage concentration, etc.,
must be set to ensure the whole process
is foam-free or very low-foaming.
- Please observe the process chemical
manufacturer’s instructions.
De-foaming agents, especially silicone-
based ones, can cause the following:
- Deposits to build up in the wash cabinet
- Deposits to build up on the load items
- Damage to elastomers and plastics in the
cleaning machine
- Damage to certain plastics (e.g.
polycarbonate and plexiglass) in the load
items being processed
- De-foaming agents should be used in
exceptional cases only; for instance, when
absolutely essential for the process.
- The wash cabinet and accessories should
be periodically cleaned without load items
and without de-foaming agent using the
Special 93°C-10'
programme.
