Manufacturer Information

Rosenmund

Rosenmund equipment is widely associated with industrial filtration and drying systems used for contained batch processing of solids and slurries. Agitated filter dryers combine multiple process steps—such as filtration, washing, agitation, and vacuum drying—within a single enclosed vessel.

This Rosenmund RSD-3 / Model RSD-0.3-528-89 Filter Dryer features 316L stainless steel product-contact surfaces, a 304L stainless steel jacket, hydraulic agitation, side discharge, and an included APOVAC liquid-ring vacuum system.

Description

Available for sale is a used Rosenmund Filter Dryer, Model RSD-0.3-528-89, with approximately 0.3 square meter filtration area and a stated maximum vessel capacity of 45 gallons.

Product-contact surfaces are constructed of 316L stainless steel. The internal vessel is rated for 100 PSI / full vacuum at 400°F, allowing operation across a broad range of compatible pressure and vacuum processing conditions.

The vessel incorporates a 304L stainless steel jacket rated for 150 PSI at 400°F, providing capability for circulating a compatible heating or cooling medium during filtration, washing, or drying operations.

A hydraulic agitator provides mechanical product handling within the vessel, while the side discharge facilitates removal of processed solids or cake.

The package also includes a vacuum pump, receiver, and control panel, including an APOVAC 3.2/850 PMZF2510 liquid-ring vacuum pump skid mounted with receiver.

Built in 1990, the vessel is identified with National Board No. 911. Current pressure-vessel condition, documentation, inspection status, and suitability for the intended service should be verified before operation.
