My “First 100 Days” as a
Service Technician in the
Paper Chemicals Division.
My name is Oliver Fricke, I am 28 years old and I work as a
Service Technician for Northern Germany and the Netherlands.
I have been part of the Kolb family since 1 August 2011.
As a trained Papermaker and Paper Technician I have always
been interested in the brilliant technological achievements
of paper production to which Kolb makes a contribution, as is
generally known. My “first 100 days” are now over and many
outsiders may ask themselves what a Service Technician actually
does, so here is a short description:
A major part of my role is monitoring systems in the area of
deposit, foam and air control as well as in the area of machine
clothing optimisation, where cleaning and conditioning are
very important. The target values, such as the cleaning intervals
or air content before the headbox, are decisive in the control
of solutions. These are worked out in collaboration with the
customer, Sales and the Product Managers.
Applications in the area of deposit control, for example, consisting
of a Natudisp deposit dispersant (successfully used to
reduce the biocide consumption) in combination with a biocide
(Mucosin/Microcid) and a system cleaner, require regular
monitoring. Bacterial counts are determined thereby depending
on the concept. Parameters, such as the pH value, redox potential,
conductivity and temperature, are measured at key points
in the system. The BDC device, an in-house Kolb development,
is often used for the continuous monitoring of the application.
This can continuously measure the layer thickness of deposits
at up to three different places and also transfer this onto the
PCS depending on customer requirements.
One of my responsibilities is to regularly check the applications
in the area of foam and air control based on the defined service
agreement. With foam control, where our Paracum concentrate
defoamers are used, it is possible to see visually whether
the desired effect is achieved or whether, for example, the dosing
point should be switched. With air control, where we often
work with our deaerator dispersions, the handheld online air
measuring device (KLG-98) is a great help in implementing and
controlling the application. In addition, air measurements are
carried out manually with the EGT probes at different points,
such as thick stock, in white water and before the headbox,
in order to check the dosing system.
