This Vollrath EWTHV-0.5 is a dissolver, a type of mixer and blender used to disperse, dissolve, or homogenise solid and liquid materials — sometimes referred to as a high-speed disperser — commonly found in laboratory and small-scale production environments handling paints, coatings, adhesives, inks, and similar formulations. Vollrath is a recognised manufacturer of mixing and dispersing equipment serving a range of industrial and laboratory applications.
This particular unit, serial number 20.611, dates from 1984 and is offered in used condition from Barneveld, Netherlands. It is powered by a 0.37 kW motor running at 380 V, with a rated speed of 1,375 rpm. Notably, the machine is equipped with a variable speed drive, giving an operational mixing shaft speed range of 350 to 1,750 rpm, allowing the operator to match agitation intensity to the process at hand.
The machine accepts dissolver discs in four diameters — 30, 50, 65, and 90 mm — providing flexibility for different vessel sizes and batch volumes. The clearance between the shaft and the frame measures 200 mm, and the mechanical lifting system allows the head to travel up to 250 mm, making it straightforward to raise and lower the shaft for vessel changes or cleaning. An on/off switch is included as standard.
Physically, the unit has a compact footprint of 0.55 × 0.45 m and stands 0.95 m tall in total, making it well suited to bench-side or floor-mounted laboratory use. A significant specification for many users is that this dissolver is ATEX compatible, confirming its suitability for operation in potentially explosive atmospheres where solvent-based or flammable materials are processed.
