Application and dosage:
neodisher Z is used in washer disinfectors for
neutralisation and/or acidic pre-cleaning. The
dosing amount depends among other things on
the application.
When using neodisher Z the following parameters
are recommended:
For neutralisation 1 - 2 ml/l
For acidic
pre-cleaning/cleaning
Suitable dosing devices are to be used.
For avoiding water stains, the use of deionised
water in the final rinse is recommended. At the
same time this protects anodised aluminium.
When using neodisher Z for pre-cleaning the
items to be washed, the washer resp. washer
disinfector and the waste water pipes must be
acid-compatible. Eternit (fibre cement) and castiron pipes are unsuitable and require a prior
neutralisation of the effluent solution.
