To heat up 200 litres from 20°C to 70°C will take approximately 2 hours with 6 kW
and 1 hour with 12 kW. Heating times are not including the effect of the material in
the heat exchanger, this differs per content and temperature of “other” side of heat
exchanger and ambient temperature. Figures are for liquid and CIP unit only.

When the cleaning is finished: Stop the pump and switch off the heaters.
CIP equipment must never be left unattended. In case of unexpected pump stop, like for
example power failure, valves V03, V04 and V08 must be closed to avoid uncontrolled
backflow from the heat exchanger and valves V05, V02 and V12 should be opened to
allow ventilation to the top of the heat exchanger to avoid pressure build up. This is
especially important when a CIP 400L is in operation since a power failure and free
draining to a single tank causes a major risk of overflow.
