KEOFITT CIP RECIRCULATOR USER MANUAL V.2

PAGE 15

10. ALTERNATIVE CLEANING AGENTS

As an alternative to alcohol you may use traditional CIP agents (alkali, acid and rinse water) and perform 

a small local CIP of the sampling valve.

The procedure is very much like what is described above for alcohol, except for the fact that you may 

need 2 or 3 bottles:

One bottle for the alkali

One bottle for the acid (only if acid cleaning is also necessary)

One bottle for rinse water (letting rinse water flow to drain)

NB!

 This User Manual does not recommend one or the other cleaning agent or cleaning proce-

dure, as they may differ a lot from one industry to another, and even companies within one given 

industry.
