Pilot unit filter dryer for laboratory applications
Efficiently manage filtration and drying processes with precise temperature and pressure control, making it ideal for testing and small-scale production of sensitive materials.

Filters and Dries Slurries in Pilot Batches
The COMBER Pressofiltro® Series PF 5 – PF 100 Pilot Plant units from the HEINKEL Group are designed for precise filtration and drying in pilot and laboratory settings. Engineered to cGMP and FDA guidelines, these units provide versatile processing for pharmaceuticals, chemicals, and food products, converting slurries into dried solids like active pharmaceutical ingredients and specialty chemicals. Each unit employs an efficient filter dryer mechanism, housed in compact skid-mounted systems for easy integration into R&D labs or small-batch production lines.
These pilot units support capacities from 8 to 100 liters and feature interchangeable vessel bases for conversion to conical bottom or Nutsche dryers, enhancing flexibility across applications. The equipment’s heated, stainless steel or Hastelloy contact surfaces ensure uniform drying while resisting corrosion. A PLC-controlled system facilitates automation and seamless integration into existing setups. Customizable options include steam sterilizable and aseptic designs, dust filters, sampling valves, and CIP systems, all of which simplify maintenance and enhance safety and cleanability, making them ideal for moisture-sensitive processes.
