With assembly of the lines make sure that
•
a liquid generally flows within one letter code only
•
the liquids are positioned in the opposite direction, for example:
o
Oil to be cooled:
▪
Inlet A1
▪
Exit A2
o
Cooling water:
▪
Inlet B2
▪
Exit B1
o
Side B is provided with one more drain on site which allows to fully
enclose the hot medium. The cooling capacity is fully used in this
way.
o
Side A is intended for connecting the medium with the highest
temperature.
•
Rinse the plate heat exchanger with the same liquid/medium as the
other system.
•
Filter the liquid/the medium after rinsing.
Illustration 2: Connection of lines
Please make sure that the medium used does not show any dirt. In order to avoid any
blockages or damages on the oil/water cooler you have to make use of a filter.
A mesh size of filter of approx. 20 µm is usually sufficient.
!
Please note that the use of chlorous water, salt water etc. is not suitable for oil/water
coolers. Damages caused by corrosion cannot be excluded.
