1. Lower levels of chloride ions may cause corrosion due to
other factors.
2. Halogens, e.g. bromides and flourides may also cause
corrosio n .
Insulation
If the heat e xchanger will be operated at very hot or very cold
temperature, take protective actions, such as insulation, to
avoid injuries. Be certain t o follow all loc al regulations.
Heating and cooling insulations are available as a ccessories.
Be aware that temperature limits of ins ulation and the heat
exchanger can be different.
Shut-down
Note!
If several pump s are included in the system, make
sure you know whic h one should be stopped first.
1. Slowly reduce the flow rate in order to avoid water hammer.
2. When the valve is closed, stop the pump.
3. Repeat steps 1–2 for the other me dium/media.
4. If the plate heat ex changer is shut down for a long per iod, it
should be dra ined.
Also, drain the heat exchanger if the pr ocess is shut
down and the ambient temperature is below the freezing
temperature of the med ia.
Depending on the media processed, rinse a nd dry the heat
exchanger and its connections.
