Shelf life of detergents

All chlorinated, alkaline liquid detergents
have a limited shelf life. Ideally, these type
of products should be consumed within six
months from the manufacturing date. The
reason for this is that the active chlorine
components decompose with time, which
reduces the detergent's ablility to disinfect
and dissolve proteins. Consider the
following:
• Make sure detergents are consumed
before the use-by date or within six
months from the manufacturing date.
• Do not buy quantities that will last longer
than three months. Avoid buying
containers larger than 25 kilograms (20
litres).
• Do not store detergents at temperatures
above 25 °C, for example in the machine
room or other warm rooms/compartments.
See the manufacturer's advice for
additional notes about storage.
Dosing parameters
Note: Never change parameter settings
without first consulting your DeLaval service
engineer.
Maintenance and calibration
There is no need for calibration of the
detergent pumps. A pressure sensor,
placed on top of the sensor pipe, ensures
correct dosing of detergents. The
maintenance point below is important to
sustain correct dosing of detergents. Note
that the maintenance task should be
performed by an authorised DeLaval service
engineer.
• The tubes in the detergent pumps should
be replaced at least two times a year.
