PSS20

Particulate Sampling System

Dynamic Diesel Emission Technology
Higher demands for cost reduction, enhanced process and engine control efficiency, coupled with increased environmental awareness is pushing the development of faster, more cost effective, and more sensitive next generation particulate analyzers. With years of advanced technical development and particle monitoring experience these demands have been met with the PSS20 Particulate Sampling System. The PSS20 system is a partial flow dilution microtunnel designed for sampling diesel exhaust gas, diluted or not, transient or stationary, to determine particulate emission levels. The principle of partial sampling of gases makes it possible to utilize the system on any size diesel engine from a few KW to large naval engines in any test cell or location. The PSS20 is designed for today’s new engine concepts and with today’s diesel engines lower than ever particulate output can provide precise gravimetric particle measurements. Cost effectiveness exists as the PSS 20 can replace the costly and complex CVS method of PM measurements. National and International PM sampling regulation requirements such as EEC, ISO -8178, and ISO 16183 are met or exceeded. The application flexible system consists of two main units. A mobile control cabinet and one mobile sampling and dilution unit. This allows the system close proximity to the engine and at most any orientation to accommodate any test cell configuration.
