Data points from literature are refined into a single correlation defining dry-tray pressure drop in sieve trays The sieve tray has been in the marketplace as a distillation device for many decades. It has been used extensively on distillation tray…
Characterizing mixer impellers on the basis of power, flow, shear and efficiency Mixing has been defined as “the application of mechanical motion in order to create fluid dynamic effects that achieve a desired process result” [1]. The process result is…
The DuoLine two-stage high-performance rotary vane pumps (photo) cover all low- and medium-vacuum applications, achieving pumping speeds of 1.25 to 11 m3/h. Applications range from mass spectrometry or optical coating to critical industrial applications, such as drying processes, metallurgical processes…
The new Veco-Drive electric superimposing gear (photo) combines a mechanical planetary gear with frequency-controlled servo motors. Since the gears only need a small part of the rated power, an overall component efficiency of more than 97% is reached, says the…
This company’s next-generation Biostat STR (photo) is a fully scalable, single-use bioreactor family based on a conventional stirred-tank design. This new bioreactor range featuring upgraded hardware and software, as well as a fully integrated, new design of Flexsafe STR single-use…
The Mixproof Valves valve matrix (photo) is designed to increase product safety, improve cleaning conditions and eliminate risk of cross-contamination, says the manufacturer. The valve matrices can be supplied pre-assembled and pre-tested, as well as fully wired and with all…
The Mobrey Hydratect 2462 detection system (photo) is used in applications where the detection of water or steam is vital, such as boilers, steam drums and steam-line drain pots. A functional safety assessment carried out by Exida determined that the…
Mixing, granulating, coating, drying and heating and cooling can be performed in this company’s “single-pot” process developed for the food industry. The process performs chemical reactions or mechanical product treatment in one machine; several process steps can take place without…
VarioPur (photo) is a new product range that includes three high-performance materials based on thermoplastic polyurethanes (TPU/AU). Both abrasion and extrusion resistance are at least five times higher than those of the traditional material, NBR (nitrile butyl rubber). The three…
The new fillpac bag placer (photo) enables efficient bag filling for materials from the construction, cement, mineral and chemical industries. With its standardized modular design, the fillpac provides numerous setup options. For instance, users can set it up at any…
