High-end solutions tailored to your needs


The knowledge and experience gained over the years allowed the development of another in a long line of Krämer firsts: The WIP deduster introduced in 2000. Pioneering innovations and continuous improvements to meet our customer's requirements have led to the new generation of KD70 WIP dedusters. They set another standard in high-containment (OEB5) in the production of highly active and potent products.

Tablet Inlet

The product inlet utilizes a Tri-Clamp flange for dust tight connections. The inlet can be rotated 360° independent of the outlet. With the use of optional inlet adapters, the deduster is easily adjustable to various tablet press discharge configurations.


Helix with integral highly efficient washing nozzles for minimal water usage, less than 50 l/min. Innovative water supply through helix center column. Modular helix for easy assembly and disassembly, no tools are needed. Helix is capable of handling tablets from diameter 3-35 mm as well as all sizes of capsules.


The KD7070 deduster has a dust-proof and removable PETG window for optimal process insight. The window is sealed against dust and water in order to meet the requirements for hazardous dusts OEB 5. The window allows easy access for easy removal of the helix for cleaning.

Easy to use control panel

The KD7070 utilize the KC7020 frequency controller. The KC7020 utilizes an acceleration sensor in the drive to determine the optimum operating frequency for ease of operation. The LCD screen allows the operator to turn the machine on and off, and to chose the necessary conveying speed to operate with the press. The KC7070 remote operation feature allows for connection and operation through the press controls if so equipped.


The optional HEPA filter class H14, manually actuated, ensures the highest safety for the operator.

Drain Valves

The optional 4 way drain valve system can be manually actuated allowing for easy handling of the dust collection and water drain.


The KD7070 deduster has been independently tested and certified to meet OEB 5 containment levels in accordance with ISPE – SMEPAC requirements as well as the EC Machinery Directive 2006/42/EC and Directive 94/9/EC (ATEX-95).
