1. The Clean-in-Place (CIP) is a method of cleaning the interior surfaces of pipes, vessels, process equipment, filters and associated fittings, without disassembly. The benefit to Use MECHWAT CIP System is that the cleaning is faster, less labor intensive and more repeatable, and poses less of a chemical exposure risk to people.The Steam-In-Place (SIP) System is responsible for repeatedly steaming areas of product contact, including vessels, flow paths, and sample ports. This may be done to reduce the bio-burden on the system, or to kill harmful materials at the end of a batch. A MECHWAT SIP system will ensure that all areas being steamed have been exposed to live steam for an adequate time to ensure the desired Ã¢â‚¬Å“killÃ¢â‚¬ effect.
