Turn-off

In case of the system equipped with several
pumps determine the correct sequence of their
stopping, then:
1. Reduce the flow rate of the medium slowly in
order to avoid water hammer.
2. Turn off the pump when the valve is closed.
3. Repeat the steps 1-2 for the other medium.

Guidelines

1. Stainless steel is susceptible to corrosion as a
result of the reaction of chlorine ions.
Therefore avoid the compounds containing
chloride salts NaCl and CaCl . The maximum
content of chloride ions in water is presented
in Fig.10
maximum content of chloride ions should not
exceed 50 ppm.
2. Do not use hydrochloric acid with the plates
made of stainless steel.
3. Chlorine reduces resistance to corrosion in
stainless steel.
4. Rinse the heat exchanger thoroughly.
4.2.

Cleaning

Pass the stream of cleaning liquid at least 1,5-
times greater than the stream during the
operation through the heat exchanger by means of
the pumping system. The cleaning liquid should be
selected for the kind of deposits in the heat
exchanger. When water is used the most popular
deposit is lime scale CaCO or iron trioxide Fe O .
