NOTICE
Risk of corrosion!
The coolant must not react aggressively with the
pipe material of the pressure vessel or the ma-
terial of the end covers.
K033N/H(P) .. K4803T(P) / OW401 .. OW941
(Standard design)
pipes: copper, end covers: grey cast iron
K033N/H(P)B .. K4803T(P)B / OW401B .. OW941B
(seawater design)
pipes: copper-nickel-alloy, end covers: coated plastic
As a free service, BITZER will examine the suitability of
pipe materials if a water analysis is provided. The basis
for the examination is the current status of knowledge.
However, due to the complexity of the situation, no ab-
solute guarantee can be given that materials will be
corrosion proof.
3.1 Plant registration
Condensers and oil coolers are pressure vessels ac-
cording to the Pressure Equipment Directive 2014/68/
EU. For this reason the entire plant must be registered
with the supervisory authority and duly approved in ac-
cordance with the local regulations.
The category for the conformity assessment of each
pressure vessel is listed in the following table.
For the inspection before commissioning and recurring
inspections, national regulations must be considered
(for example the Industrial Safety Regulation (Be-
trSichV) in Germany).
In non EU countries local regulations must be complied
with.
