The company is dynamic and prosperous, with core values centred on the human aspect in its relationship with its staff and clients.

Core business

Instrumentation integration and comprehensive service

Field instrumentation services cover the entire project chain: study, consulting, installation, maintenance, and monitoring of devices as well as supply of ancillary services. To address client problems, CNS relies on technical experts with extensive field experience. Multi-disciplinary teams develop comprehensive, specific, and integrated solutions tailored to the project environment that extend beyond the specific field of instrumentation. CNS pays special attention to customer service through on-site response teams and robust services.

The expertise of CNS services is based on an extensive system of contributors. As a subsidiary of SUEZ Group, CNS combines its know-how with that of SUEZ technical expertise centres. These dynamic links make innovation the foundation of the company’s core business to support development of technologies and products. This focus is the company’s strength.
