IMR 400 
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 - DRYING PRINCIPLES
PERMEATION DRYER  
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
flue-gas analyzer.
Purge gas = fresh air 

PELTIER COOLER  
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.		 Coalescing filter
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.		  Heated hose with filter and probe
