Chriwa Wasseraufbereitungstechnik GmbH - Electrics/PLC Commissioning


Experienced electric and commissioning engineers and technicians as well as skilled specialists provide a technically correct, on-time assembly and commissioning of the water treatment plants. Upgrades and expansion of plants are made with a minimum of operating interruptions.

Usually the plant control is made by a Siemens S7 ® PLC control and HMI touch panels (WinCCflexible ® or Protool ®). On demand other control systems like Rockwell/Allen Bradley, Mitsubishi, and Phoenix etc. can be implemented. Wiring diagrams are made with EPlan 5.7 or EPlan P8.


Assembly and commissioning

The assembly and commissioning of our plants are managed by our experienced commissioning engineers. Parallel to and after finishing the commissioning, our engineers train and instruct the operation personnel of the customer. A detailed and comprehensive technical documentation ensures a smooth plant operation.


Service / Remote Diagnosis

Our PLC-controlled plants are equipped with a remote diagnosis tool according to the requirements of the customer (telephone-modem, ISDN-modem, VPN access etc.) to enable the fastest possible online diagnostic and trouble shooting in case of disturbance. Online remote plant control as well as a remote optimizing of operational parameters are possible, too.
