Commissioning / Testing effectiveness
Each System that leaves Meech is fully tested and the test report will be included in the packaging and
can be requested if required.
To commission the system, follow the installation guide and get the system ready to run with the
vacuum pressure set to 2.5KPa or the required pressure for the system. There will need to be a web in
place to monitor the effectiveness of the cleaning performance.
Commissioning Test Requirements
To conduct the commissioning, you will need:
•
Source of known contamination (web may be a contaminated web but a known source of
contamination will be added to the web to test cleaning performance)
o
Preferably a different colour to the web
o
Dry and loose contamination only
•
A method of marking out an area
o
Masking tape is the best option or marking directly on the web in a marker pen
•
Measuring device that can go as low as 10-12mg (10mg spoons can be requested from Meech)
o
When applying larger contamination like plastic particulates more contamination can be
added but a realistic amount of contamination should be added.
Commissioning Test Procedure
1. Mark out A5 area on the web (roughly 140 x 210mm rectangle), Use tape or a Pen to mark the
area.
a. Make sure this area is marked before the web passes through the web cleaner
b. It is best practice to label the area with the test number to ensure this is picked up in
any pictures or test reports
2. Apply the known contamination (10-12mg) over the marked-out area ensuring there are no
clumps of material. Contamination of larger particulates should be added in such a way that is
representative of the contamination of the installation.
3. Photograph the contaminated area as best as possible and make notes as to the locations of the
contamination.
4. Turn the system on and allow for it to reach the set target pressure, this would normally be
2.5KPa but may differ in different applications.
5. Run the web through the VacClean head and inspect the area of web previously marked out.
Making sure to photograph the area for comparison.
a. For the system to be functioning as expected it should have removed a minimum of 85%
of the known contamination.
