Filter Media Test Rigs » MMTC system

Practical testing of cleanable surface filters in accordance with standards and based on customer preferences

  • Standardized test in accordance with VDI 3926
  • Individual tests under close-to-real conditions as defined by the different process conditions, e.g. in the cement industry, in the wood-processing industry, the pharmaceutical industry, the chemical industry, in nuclear power plants and many other areas...

The MMTC series offers ultra-precise, reproducible testing systems for the development and quality control of cleanable filter media.

The test rigs in the MMTC series enable testing of filter media with different test dusts. They can be supplied with heating up to 250°C and with adjustable relative humidity of up to 80%. Special sampling probes enable in-situ measurements in the filter housing. With the aid of specially shaped filter holders, the so-called garland effect on a filter hose during cleaning can be simulated.

In addition, with the aid of the aerosol spectrometer Promo® the particle concentration and particle size distribution can be determined with the highest time resolution. The test specimens can therefore be accurately analyzed during the cleaning pressure burst, and the cleaning parameters can be optimally fine-tuned to the medium.

The advantages of the MMTC series allow a clear, cost-effective and practically useful comparison of cleanable filter media and exceed the requirements of the standards VDI 3926 and ISO 11057.
