Certain agents, intermediates and extracts make complex demands on the processes of filtration/drying, whether by corrosive effects on the ambiance or by high sensibility against metals, contamination or temperature. This is why Rosenmund® also offers glass-lined Filter/Dryers. The surfaces and components in contact with the product are covered with high quality steel-enamel. This specification is distinguished by a very large constancy against high corrosive media, as well as against abrasion and offers a large spectrum of application regarding operating temperature and pressure. The low roughness of the surface of enamel allows the user a cleaning of the vessel on CIP-level. Thereby the danger of mixing product-batches and residua is decreased (Cross-Contamination).
THE POWER OF ENGINEERING - We offer custom-engineered solutions for your filtration, drying and solids handling applications in the chemical and pharmaceutical industry:
Mobile Nutsch-type filters up to 0,3m² with no metallic process wetted parts
Mobile filter dryers for kilo labs (ROLAB)
Filter dryers up to size 16m²
Double conical dryers
Pneumatic solids conveying systems, vacuum conveyors, dense phase powder transfer systems
Solutions for automated precision filling of reactors and big bags
We also provide insulators and containment solutions for these units to ensure safe operation when processing hazardous substances. Depending on the intended application, our products are made in stainless steel, Hastelloy and/or other special alloys. Alternatively, they are available in non-corrosive De Dietrich® glass-lined steel or QVF® borosilicate glass 3.3. Our brands ROSENMUND® for filters and dryers, De Dietrich® for glass-lined components and QVF® for equipment made in borosilicate glass 3.3 stand for excellence in product quality and process safety and conform to all relevant national and international standards and regulations. For synthesis, crystallization and precipitation, we offer reactors made in QVF® borosilicate glass 3.3 with capacities of up to 500 liters and units made in De Dietrich® glass-lined steel holding up to 140m³. We also provide tailor-made process solutions for the mixing and dispersing of liquid products. We specialize in the design and manufacture of turnkey plants for synthesis, solvent processing, formulation, solids handling and conveying as well as filling. You can thus avail of a complete solution from a single supplier. We advise you in process development and assist you in choosing the best equipment for your process. We are highly experienced in GMP validation and qualification of plants, as we have been applying the relevant standards for many decades, keeping up to date with the latest developments. More than 330 years of experience in the field of lab equipment and long-term, close business relationships with our customers form the basis of our expertise in process technology. We operate a global network of branch offices. After commissioning, our service teams will assist you on site at anytime and anywhere in the world. We also offer general plant overhauls and re-glassing to manufacturer standards at our production plants.
