Chriwa Group - Water matters. We care.

Electrical / Commissioning

 
Experienced electrical technicians and commissioning engineers as well as continuously trained specialist staff ensure the technically flawless, on-time installation and commissioning of the water treatment plants. Renewals and extensions of plants are carried out with a minimum of interruption to operation.

Control

The plants are usually controlled with S7-1500 ® controllers and HMI touch panels of type TP 1200 - TP 2200. The development of the control software and the touch panel projects is carried out with the current version of the TIA-Portal® software.

Other control systems such as Rockwell/Allen Bradley, Mitsubishi, Schneider etc. are also possible on request.

Circuit diagram documents are created with EPlan P8.

Installation and Commissioning

The installation and commissioning of our systems are managed by our experienced commissioning engineers. Likewise, the proper instruction and training of the operating personnel at your site is carried out by our commissioning engineers parallel to and following the commissioning. This, together with technically detailed, comprehensive documentation, ensures that your own systems operate perfectly.

Service / Remote diagnosis

For remote maintenance of our systems, a VPN router of the MGUARGD type is usually integrated into our switchgear. The VPN connections are managed directly at our premises and the central MGUARD is located at our premises. On customer request, other connections such as mobile routers, telephone modems or customer-specific VPN connections are also possible. This ensures the fastest possible help in the event of a fault. Via this online connection, we can directly access your water treatment and, for example, diagnose errors, optimise control parameters, etc.
