PLATE AND FrAME - HEAT ExCHANgErS
The following is the procedure for cleaning
in place;
1) Shut off all the valves and completely
drain the heat exchanger.
2) Flush both sides of the unit with
100 ºF to 120 ºF water until the stream is
clear and free of any process fluids.
3) Drain the rinse water completely from
the CIP system.
4) Fill the drained CIP system with water
and add the appropriate cleaning solution.
Cleaning In Place (CIP)
with cleaning agents is recomended for applications where frequent
fouling of the heat transfer plates occurs. When the application is extremely corrosive, cleaning
in place can prolong the life of the plates.
5) Circulate the cleaning solution through the heat exchanger at 140 ºF for 3-6 hours or as re
-
commended by the cleaning solution manufacturer.
6) Drain the cleaning solution and flush the unit again with warm water following steps 2 And 3.
7) You can now close the valves to the CIP/cleaning solution system and reopen the main Valves
to the heat exchanger.
8) Start up the heat exchanger in accordance with section 4.2.
