PSS-20 Test Cell Unit

Sampling a particulate from a high velocity, high temperature and high pressure system is not as easy as sampling a homogeneously mixed gas sample under the same conditions.

The PSS-20 is  a particulate sampling system that has been based on the partial flow method and incorporates variable dilution to comply  with all the specifications contained in primary EU and US regulations for the homologation of diesel engines from light duty all the way up to heavy duty- both on the road and off road.

The performance of the PSS-20 allows one to perform both transient and steady state testing whilst assuring excellent correlation with full flow systems such as the CVS type of sampling / dilution equipment.  The principle of exhaust gas partial sampling makes it possible to use the system with every kind of engine, from ultra-light vehicle units up to large naval engines and vehicles. Moreover, the PSS-20 can be used as a secondary dilutor when used in conjunction with CVS systems.
