Chemical processes and technology
Associated process chemicals
Problem
The ingredients in process chemicals have
a significant impact on the longevity and
functionality (throughput) of dispensing sys-
tems.
Process chemicals can damage elastomers
and plastics in the machine and acces-
sories.
Hydrogen peroxide can release large
amounts of oxygen.
The following process chemicals can cause
large amounts of foam to build up:
- Cleaning agents and rinsing agents con-
taining surfactants
Foam can occur:
- in the program phase in which the
process chemical is dispensed
- in the subsequent program phase if it has
been spilt
- in the subsequent program if rinsing agent
has been spilt during dispensing

Solution
- Follow the process chemical manufac-
turer's instructions and recommendations.
- Carry out regular visual inspections of the
dispensing system to check for signs of
damage.
- Check the throughput of the dispensing
system regularly.
- Ensure that the regular cycle of mainte-
nance is observed.
- Contact Miele for advice.
- Follow the process chemical manufac-
turer's instructions and recommendations.
- Carry out a regular visual check of any ac-
cessible elastomers and plastics for dam-
age.
- Only use validated processes.
- The wash temperature must be lower than
158°F (70°C) when using hydrogen perox-
ide.
- Contact Miele for advice.
- Process parameters in the wash program,
such as dispensing temperature and
dosage concentration, must be set to en-
sure the whole process is foam-free or
very low-foaming.
- Please observe the process chemical
manufacturer's instructions.
