- Mill-Gard CO Detection System



The Mill-Gard CO detection system provides early warning of a fire within coal pulversizers and silo’s. Designed specifically for use in coal-fired power stations, the system uses powerful pumps to extract air samples from the coal mill via hardened sample probes. The air samples are conditioned and passed over industrial grade C.O. (carbon monoxide) sensors to quickly detect an increase in C.O. gas levels. Any increase in C.O. levels provides an early indication of the onset of fire.
