This DE Dietrich SR-250 is a drum dryer — also known as a tumble dryer or double cone tumbler dryer — designed for drying bulk materials under controlled temperature and pressure conditions in a rotating vessel. DE Dietrich is a well-established manufacturer of process equipment, particularly known for glass-lined and enamelled reactors, vessels, and dryers used in the pharmaceutical, chemical, and fine chemical industries.
This particular unit, serial number 25394, was manufactured in 1997 and is offered used from its current location in Barneveld, Netherlands. The drum is fabricated from glass-enamelled steel, grade 3009U, providing excellent chemical resistance and making it suitable for handling reactive, corrosive, or sensitive materials. The vessel has a total capacity of 285 litres, with a cylindrical diameter of 772 mm, a cylindrical length of 344 mm, and conical lengths of 293 mm and 168 mm respectively.
The dryer operates at a working pressure of 6 bar and supports vacuum operation. The heating jacket — with a capacity of 90 litres — operates at a working pressure of 10 bar and is also vacuum-capable, allowing precise thermal control across a temperature range of -30 °C to +200 °C. Material is loaded through a manhole inlet with a diameter of 400 mm and discharged through an outlet of 200 mm diameter.
The drive motor is rated at 0.75 kW, 400 V, and is specified as Ex-rated, meaning it is suitable for use in potentially explosive atmospheres. The machine occupies a floor area of 2.5 × 1.2 metres and stands 2.8 metres in total height.
