Pilot plant filter dryer for small scale production
Optimize filtration and drying processes in your pilot plant with a versatile solution designed for seamless integration into small-scale production lines, enhancing efficiency and precision in handling sensitive slurries and cakes.

Filters, Dries, and Mixes Pilot-Scale Products
The COMBER Pressofiltro® / Turbodry® Series PF/TD units by Heinkel are versatile pilot plant filter and vacuum dryers designed for industries such as pharmaceutical, chemical, and food processing. Specially engineered to perform processes like filtration, drying, and mixing, they cater to operations that require small-scale production or pilot testing. This equipment is ideal for end-products like active pharmaceutical ingredients, epoxy resin powder coatings, and synthetic pigments.
Constructed in accordance with the Pressure Equipment Directive 97/23/EG and ASME U-stamp, these units are compliant with GMP and FDA guidelines, ensuring certification for pharmaceutical applications. They operate safely in ATEX danger zones (group II 2G 2D, zones 1/21) thanks to their explosion-protected control system (EEx-d). Built on a skid with a secure shaft seal via a gland nut, they support easy integration within existing production lines.
Customization is available, featuring a multilayer PLC system to enhance automation and process control. This series caters to Research & Development, laboratory, and processing departments seeking efficient filtration and drying of slurry and cake types. The equipment is also engineered for ease of maintenance with its robust design and materials suitable for a range of industrial environments.
