On site, we presented the scattered light-based aerosol spectrometer Promo ® 3000 H with heating regulation up to 250 °C for welas® aerosol sensors, the fine dust measuring system Fidas ® Frog , the new autonomous aerosol generator PAG 1000 and the modified dust measuring device DustView II for the comparison of dust development from powders and bulk material.

The condensation particle counter UF-CPC 100 from Palas® is now in operation in the Alps at an elevation of 3,106 meters at the Observatory Sonnblick.

Sonnblick Observatorium_frei FW_1.JPG The highest meteorological observation station of Austria, operated by the “Zentralanstalt für Meteorologie und Geodynamik (ZAMG)” in Vienna, has been in operation for over 130 years, nearly without interruption. Since 1986, air chemistry background measurements are also performed at the observatory in addition to meteorological observations. Apart from many other research projects, studies on air quality management and the transport of air pollution were expanded during the past years and climate research was accelerated.

Since November 2016, the condensation particle counter UF-CPC 100 was first in operation during a trial measuring campaign and was then delivered to the researchers of the observatory in August 2017.

The UF-CPC 100 measures the total particle concentration of ultrafine and nanoparticles in the air or other carrier gases. A special advantage of the measuring device, which also convinced the operators of the Observatory Sonnblick, is the innovative and patented supply of the working fluid. This permits using water as working fluid, in addition to the standard operation with butanol.

A Palas® Promo 3000 H with two heatable welas® aerosol sensors supplies reliable data on particle concentrations (quantity and PM-values) and particle size distributions of fine dust particles already since 2015 at the observatory. What’s more, the heatable welas® aerosol sensors allow performing studies on cloud and droplet formation through temperature effects.

Apart from electric power, compressed air is the second most frequently used energy carrier in industry and trade, and its absence from the modern working environment is inconceivable.

Hospitals, the pharmaceutical and foodstuff industry, auto repair shops, paint shops, the electrical industry and many other sectors utilize compressed air. The purity of the generated compressed air is critical for many applications. Especially oil particles and fine dust must be separated reliably. Beyond this, energy efficiency and thus the operating costs of the compressed air installation depend on the quality of the compressed air filters used for particle separation and the associated differential pressure.

With the compressed air filter test rig DFP 3000 from Palas®, complete compressed air filter elements are tested directly under overpressure up to 7 bar resembling real conditions extremely closely. This is unparalleled worldwide. The fraction separation efficiency, i.e. efficiency according to the particle size, as well as the pressure loss developing during loading, are reliably tested under overpressure. Another unique feature of the DFP 3000 is the capability of testing the function of individual or multiple layers of filter media.

DFP 3000 with flat sheet media holder The DFP 3000 convinces a growing number of users internationally with its special advantages. Three companies in Germany already employ this system for filter testing; three other test rigs were delivered to China and one to Italy. An order for another system was already received from the U.S.

Our sales partner Cross-Tech Equipment from Shanghai now uses the ultralight Fidas® Fly 200 for fine dust measurements in China. The complete system, consisting of HORUS drone and fine dust monitor, is distributed by our partner Airclip GmbH, who also offers orientation on operating the drone and the fine dust measuring device. In March the colleagues from China visited Dresden and passed their “pilot training” there for the flying fine dust monitor.

Palas® has developed the bioaerosol calibration chamber CCB 3000 for characterizing and comparing bioaerosol generators and bioaerosol collecting systems.

CCB-3000_freigestellt.jpg The CCB 3000 already complies with the requirements of the latest VDI-Guideline 4258, which is currently being prepared and describes chambers and test channels for characterizing and comparing bioaerosol generators and collecting systems. The CCB 3000 was developed and built upon suggestion of Univ.Prof. Dr. Joseph Strauss from the AIT Tulln (Austrian Institute of Technology GmbH) by Palas®.

Aerosols from different starting materials can be used in the bioaerosol calibration chamber. Various dusts (Arizona test dust, wood dust, dust from agricultural operations) and suspensions (fungi and bacteria suspensions) were successfully used in the CCB 3000. Vital spores and spores capable of forming colonies could be introduced, collected and then compared in the area of fungi and bacteria spores.

Special consideration was given to the consistency of the aerosol distribution within the test chamber in all three directions, which was confirmed in the test. The bioaerosol chamber is therefore particularly excellent for the comparison or characterization of several measuring devices that shall be supplied with an equally distributed aerosol.
