Continuous analysis of CEMS emissions
Fields of application
Continuous monitoring of gas emissions from boilers, industrial furnaces, engines or waste incinerators.
Features
Fuji Electric France combines experience and expertise in the two related fields of robust, certified measurement of atmospheric emissions with Fuji CEMS, and standardized data management and reporting with Fuji DAHS. Fuji CEM Systemv7 is the latest evolution of the Fuji DAHS data management tool. It is a standardized acquisition and processing system for emission measurement data. It benefits from the latest technological advances in terms of digital, wireless, cloud-based and secure communications (for GSM), and the ability to send alerts by e-mail or SMS. It ensures strict compliance with current European regulations such as EN17255.
