Filters and Filter/
Dryers
The elementary advantages
of the innovative Rosenmund filter
and Filter/Dryer technology:
• Optimum efficiency
• Professional high performance
• Total flexibility • Easy cleaning
(CIP/WIP and SIP).
Whether in the chemical, pharmaceutical or food
industry – Rosenmund filters and Filter/Dryers
prove themselves through a very high efficiency in
washing and isolating solids, even in the most
difficult production processes. The high-performance
Rosenmund filters can also be converted to
Filter/Dryers simply and quickly, by the addition
of upgraded features.
Side discharge.
Rosenmund
Filter/Dryer 0,4 m2
The ideal application spectrum for side discharge:
Multi-purpose production with frequent product changes.
Processes with stringent
requirements for
low-particle and
sterile production.
Limited building heights.
Special design features:
Side discharge valve with
metal-to-metal seal.
Side discharge valve for pressure-tight closure
after each product discharge – without prior
cleaning of the sealing areas! Ideal for automatic
process control and contamination-free production.
Rosenmund Easiclean side discharge valve for
manual cleaning in the case of difficult products.
Two- or three-blade agitator for an efficient agitation
and discharge process.
Quick-lock bayonet or C-clamp main flange closure.

Total discharge with the
Gas Knife system.
Rosenmund Filter/Dryer 2 m2 sterile version
The Rosenmund Gas Knife
is a unique and innovative
solution that enables
a total product
discharge without
manual intervention.

Glass-Lined Filter/Dryer.
The great demand for non-corrosive Filter/Dryers
led to this joint development between De Dietrich and
Rosenmund. The innovative Glass-Lined/Hastelloy
construction guarantees maximum resistance to
chemical solutions and aggressive solvents.

Cleaning and Decontamination
(CIP/WIP and SIP).
CIP/WIP and SIP systems are an integral part of
Rosenmund’s process equipment range, including steam
sterilisation and aseptic use. The application of specialised
spray systems and sterilisation methods validation of the
vessel preparation process.
Special applications: microwave drying.
The use of microwaves for chemical processes
provides clear advantages:
Improved heat transfer to the product.
Volumetric and selective heating.
No harmful substances.
Gentle and fast drying of difficult products.
Low energy consumption.
Reduced drying times, especially in the case of
temperature-sensitive products and when conventional
heat transfer methods are difficult to apply.
