SIP & CIP with WALTHER-Quick Couplings

Since the 1950s, the cleaning of closed systems has become increasingly important.In the beginning, the systems had to be manually disassembled and cleaned when changing products or if other cleaning was required.

This method was not only time-consuming, but also drove up the process costs. Accordingly, two different main processes were developed which allow cleaning in closed systems:

Sterilization in Place (SIP) refers to a cleaning process in which all surfaces of a process plant that come into contact with the product are sterilized without major dismantling. For sterilisation, either temperature or chemicals are used over a longer period of time and under certain pressures and flow rates.
Cleaning in Place (CIP) describes a method for cleaning plants or process equipment. Typical here is cleaning without major dismantling with cleaning agents, alkalis and acids and/or with temperature in a mostly fully automated process, for example also by mulching.

This method was not only time-consuming, but also drove up the process costs. Accordingly, two different main processes were developed which allow cleaning in closed systems:

The possibility of cleaning closed systems without major dismantling opens up many advantages:
• improved safety for workers involved in the production of potentially hazardous compounds,
• faster cleaning,
• reduced water consumption,
• lower personnel costs,
• repeatable, documentable processes
