The IMR 400 is a wall-mounted flue-gas dryer, and is designed to prepare flue-gases for a wide variety of gas monitoring applications. The IMR 400 is a 'stand-alone' system that works automatically. The ruseed wall mounted enclosure meets NEMAtype 4 (IP65) classification. The first step of the flue-gas conditioning process is filtering the gas sample. The filtered flue-gas enters the IMR 400 through a heated hose. The heated hose keeps the sample hot until it reaches the IMR 400. The system then removes the water vapor with a Peltier-cooler from the hot sample. The IMR 400 is designed to prepare flue-gases for the IMR 5000 CEMS flue-gas analyzing system.
