This Vollrath EWTHV-0,5 is a mixer and blender — sometimes referred to as a dissolving mixer or high-speed dissolver — designed for blending, dispersing, and dissolving materials in laboratory and small-batch industrial applications. Vollrath is a well-established manufacturer of mixing and processing equipment, serving industries such as chemicals, coatings, adhesives, and pharmaceuticals with precision-built machines for demanding mixing tasks.
This used unit, built in 1984 and currently located in Barneveld, Netherlands, carries serial number 20.610. It is powered by a 0.37 kW motor rated for 220/380 volt operation, and is noted as ATEX-compatible, making it suitable for use in potentially explosive atmospheres — a relevant consideration for solvent-based or flammable product applications, though buyers are advised to verify this status directly.
The machine is equipped with a variable speed drive, with the motor running at a base speed of 1,375 rpm and the mixing shaft offering an adjustable speed range of 350 to 1,750 rpm, allowing the operator to tailor dispersion intensity to the material being processed. The dissolver is fitted with interchangeable discs in four diameters — 30, 50, 65, and 90 mm — providing flexibility across different vessel sizes and batch volumes. The clearance between the shaft and the frame measures 200 mm, and the mechanical lifting system offers a stroke of up to 250 mm, enabling the head to be raised and lowered for vessel changes or cleaning.
The machine's footprint is compact at 0.55 × 0.45 m, with a total height of 0.90 m, making it well suited to laboratory benches or confined workshop spaces. The dissolver function and the switching mechanism are noted as items to check on inspection.
