This Vollrath EWTHV-0,5 is a used mixer and blender — sometimes referred to as a dissolver or high-speed disperser — designed for mixing, blending, and dispersing materials in laboratory and small-batch production environments. Vollrath is a recognised manufacturer of mixing and process equipment serving industries such as paints, coatings, adhesives, and chemical processing, where precise, controlled dispersion of fluids and pastes is essential.
The machine is driven by a 0.37 kW motor rated at 380 V, running at 1,390 rpm, and is certified for use in potentially explosive atmospheres, making it ATEX compatible. A variable speed drive allows the mixing shaft to be adjusted across a broad range, from 260 to 1,820 rpm, giving the operator fine control over shear and dispersion intensity to suit different materials and viscosities.
Four interchangeable dissolver discs are included, with diameters of 30, 50, 65, and 90 mm, enabling the machine to be configured for different vessel sizes and batch volumes. The clearance between the shaft and the frame measures 200 mm, and the unit is equipped with a mechanical lifting mechanism offering a stroke of up to 250 mm, allowing the head to be raised and lowered for vessel changes and cleaning. An on/off switch is fitted as standard.
The machine carries serial number 19613 and is located in Barneveld, Netherlands. Its compact footprint measures 0.55 × 0.45 m with a total installed height of 0.95 m, making it well suited to laboratory benches or small production spaces. The unit was manufactured in 1989 and is offered in used condition.
