Chemical agents
Problem How to resolve it
The following chemical agents can
cause large amounts of foam to build
up:
–
Cleaning agents and rinsing agents
containing tensides,
–
emulsifiers.
Foam can occur:
–
in the programme block in which the
chemical agent is dispensed,
–
in the following programme block if it
has been spilt,
– in the following programme with
rinsing agent if it has been spilt.
–
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 chemical agent
manufacturer's instructions.
De-foaming agents, especially silicone
based ones can cause the following:
– deposits to build up in the cabinet,
– deposits to build up on the load,
– damage to elastomers and plastics in
the machine,
– damage to certain plastics (e.g.
polycarbonate and plexiglass) in the
load 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 a load and without
de-foaming agent using the
ORGANICA programme (if available)
or a special programme.
