Chemical agents
Problem
How to resolve it
The ingredients in chemical agents
have a strong influence on the longevity
and functionality (throughput) of the
dispensing system. The dispensing
system (hoses and pumps) should be
set up for a particular type of chemical
agent.
General types:
– alkaline to pH neutral products,
– acidic to pH neutral products
– Observe the chemical agent
manufacturer's instructions and
recommendations.
– Carry out a regular visual check of
the dispensing system for any
damage.
– Check the flow rate of the dispensing
system regularly.
Chemical agents can damage
elastomers and plastics in the machine
and accessories.
– Observe the chemical agent
manufacturer's instructions and
recommendations.
– Carry out a regular visual check of
any accessible elastomers and
plastics for damage.
The following chemical agents can
cause large amounts of foam to build
up:
– cleaning agents and rinsing agents
containing 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
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 chemical agent
manufacturer's instructions.
