WALL-MOUNTED FLUE-GAS CONDITIONING SYSTEM
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 rugged wall mounted enclosure meets NEMA type 4 (IP65) classification.
The first step of the flue-gas conditioning process is filtering the gas sample. The filtered flue-gas enters the system 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 permeation dryer or a peltier-cooler from the hot sample.
The IMR 400 is designed to prepare flue-gases for the IMR 5000 flue-gas analyzing sytem.

IMR 400 function diagram
The selective and contiuous removal of water vapor is performed by leading the
flue-gas through a tube. Water vapor is absorbed through the tubing walls and
moves through it. Dry purge gas is flowing at the outside of the drying-tube
in the opposite direction and carries the water vapor away. Virtually all elements
of the flue-gas sample remain unchanged, only the water vapor is removed.
The filtered and dried flue-gas can now be analyzed by the IMR 5000 or any other
Purge gas = fresh air
The peltier cooler is designed to reduce the dew-point of the flue-gas to about 5°C, this eliminates condensation. The hot flue-gas enters the heat exchanger and the flue-gas comes in contact with the cold wall of the heat exchanger. The immediate separation of the water vapor is the result. Again virtually all elements of the flue-gas sample are retained, except the water vapor. The condensed water exits through a tubing pump. The filtered and dried flue-gas can now be analyzed by the IMR 5000 or any other flue-gas analyzer.
IMR 400 - Filtration
Before the flue-gas enters the 'heated hose' it is cleaned by a filter
that is designed for hot gas analysis. The construction ensures a quick filter element exchange. The filter element is designed to remove 99.99% of 0.1 micron particles.
A special filter housing is available for dirty gas analysis applications.
The IMR 400 filtering system can be equipped with different grades
of stainless steel elements.
The filter can be used as a coalescing filter or as a particulate filter
simply by switching the input and output.
IMR 400 - Heated hose
The IMR 400 is equipped with a 5 ft. (1.5m) heated sample line. This 'heated hose' ensures that the extracted sample does not cool down before it reaches the drying system. A temperature
controller keeps the temperature of the 'heated hose' at approx. 140°C / 285°F.
The temperature element is either a PT100 or a thermocouple Type K.
