Detailed Specs

The sample can be taken directly from the tailpipe into the Dekati® Double Diluter setup eliminating the need for large full-flow sampling systems to carry out particle or gas measurements. Only purified pressurized air is needed to operate the Dekati® Diluter thus no flow control devices nor pumps are needed. Dekati® Diluters are manufactured with a default dilution factor of about 8. Other, specified, dilution factors are available with code DI-2002. The Dekati® Double Diluter setup is a widely used and well characterized dilution system for tailpipe emission measurements. It’s all stainless steel, no moving parts -construction makes it a robust and reliable choice for any emission measurements. The system consists of two Dekati® Diluters with the first dilution stage heated up to exhaust temperature. This method effectively reduces risk of condensation and unwanted sample transformations caused by volatile components in the sample. The secondary dilution is carried out with cold air reducing the temperature at the outlet of the dilution system to ambient level. The dilution factor of one Dekati® Diluter is about 1:8 giving the whole setup a total dilution factor of 64. Dekati® Double Diluter features: Two stage ejector diluter system with first dilution stage heated
Total Dilution factor of ~64
Sample temperature range 0 – 450 °C
Sample pressure range 800 – 1200 mbar (950 – 1050 mbar for use with pressure sensitive instruments)
All stainless steel construction, no moving parts
Extremely low particle losses, used as the golden system in comparison measurements by JRC
