Problem How to resolve it
The following process chemicals can cause
large amounts of foam to build up:
– cleaning and rinsing agents that contain
tensides.
Foam can occur:
– in the program block in which the process
chemical is dispensed,
– in the subsequent program block due to
carry-over,
– in the case of rinsing agents, in the
subsequent program due to carry-over.
– Process parameters in the wash program,
such as dispensing temperature, dosage
concentration etc. must be set to ensure
the whole process is foam free or very low
foaming.
– Observe the instructions of the
manufacturer of the processing
chemicals.
Antifoaming agents, particularly silicone-
based antifoaming agents, can cause the
following:
– deposits in the wash cabinet,
– deposits on the load,
– damage to elastomers and plastics in the
washer-disinfector,
– damage to certain plastics (e.g.
polycarbonate and plexiglass) in the load
being processed.
– Use antifoaming agents only in
exceptional cases or when they are
absolutely necessary for the process.
– Periodic cleaning of the wash cabinet and
accessories without a load and without an
antifoaming agent using the ORGANICA
program (if available).
