Its innovative design is protected by an utility model and the generated aerosols comply with the requirements regarding particle size (1 ... 2 µm) and concentrations for testing oil mist separators. The design of this generator ensures a very constant particle size distribution and concentration while at the same time providing a high degree of reproducibility.

The device features the possibility to adjust the temperature of the generated aerosols and can be used on a variety of oils. Depending on the type of oil and the pressure of the carrier gas various mass flow rates can be adjusted for a set working temperature.

Benefits

  • very stable particle size distributions and concentrations
  • generates polydisperse test aerosol with a mean particle size of 1 ... 2 µm
  • very high aerosol particle concentration and particle mass flow
  • adjustable and regulated aerosol temperature
  • selectively enabling of 1 to 3 nozzles
  • mass output adjustable via nozzle pressure and nozzle quantity
  • particle size distribution changeable via nozzle pressure and aerosol temperature
  • pressure-restistant up to 0,3 bar

Applications

  • testing of oil mist separators, for instance with the Topas Oil Mist Separator Test Rig SPT 140
  • capacity tests of filters
  • research and development

The oil is atomised via three two-component jet nozzles which are located under a baffle plate. The carrier gas and the oil are heated in the nozzle block to the set temperature.
