DSP Series — Combustion Soot Aerosol Generators

DSP 3000 | DSP 3000 H — Defined Soot Particle Generators

DescriptionDSP 3000

In the DSP 3000 series a soot aerosol is generated from the defined combustion of a fuel gas (e. g. ethene + combustion air).

The DSP 3000 and the DSP 3000 H allow the systematic adjustment of the average particle size, as well as of the mass flow of the soot aerosol generated, by the mixing air-fuel ratio.

By means of user-friendly software, the desired operating parameters can be set quickly and reproducibly on a laptop/PC. With a a generated soot mass output from up to 3 g/h, the DSP 3000 series is well suited to loading diesel soot particle filters (DPF) for filter efficiency tests.

The DSP 3000 H version adds controlled heating, up to 300°C, for volume flows up to 60 m3/h. Both the DSP 3000 and the DSP 3000 H operate up to an overpressure of approx. 300 mbar and are fitted with a comprehensive safety package.

For calibration of instrumentation used in assessments, the DSP 3010 is a small mobile generator producing an log normal soot distribution using the same principle and with an adjustable mean diameter from 10 nm to 150 nm.
