The HGK-R90D Automated CEM Controller monitors mercury emissions from coal-fired sources as specified in PS12-B. The controller mounts in a standard 19’ rack and can be placed in the CEM shelter or in our HGK-PFI platform mounted enclosure,  Two independent flow channels are controlled in proportion to the CEM flow monitor automatically. The controller may be connected to a plant network for remote program control and data access.  MODBUS® protocol is utilized for real-time data transfer and alarming to the plant CEM DAHS.
