HGK-R90D
HGK-R90D Automated Rack-mount Controller
The HGK-R90D CEM controller for appendix K of Part 75 Mercury emissions provides proven reliability in sorbent trap monitoring of flue gas mercury.
Features
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.
