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 con-
taining tensides.
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 pro-
gramme, 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 manufac-
turer'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
washer-disinfector,
– damage to certain plastics (e.g. polycar-
bonate and plexiglass) in the load being
processed.
– De-foaming agents should be used in ex-
ceptional 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 OR-
GANICA programme.
