Evaporation Technology Evaporation Test Facilities at Karlsruhe R&D Center

Availability for laboratory and pilot plant testing for different kind of evaporator systems.

With state-of-the-art pilot plants and test benches our R & D Center is optimally equipped for testing in the fields of evaporation technology.

Most pilot plants are mobile so that it is also possible to perform tests on our customers' premises. In such a case the plants can be controlled and monitored by a remote control system. As a matter of course, the process data can be recorded and processed electronically.

Our physico-chemical laboratory is designed to determine and analyze important physical characteristics such as viscosity, boiling point elevation, thermal conductivity and maximum final concentration.

Moreover, complex quality parameters can be determined in our analyzing laboratory with GC and HPLC.

We use the latest software and hardware to simulate the operating behaviour of the plants and adapt them to individual customer specifications. The determined process parameters and substance properties are directly used for the design of our plants.


The following pilot plants are available for testing:

  • Various stationary  single-tube falling film evaporators with different tube lengths, diameters, surface shape  and material of construction
  • Mobile 2-effect falling film evaporator for different arrangements on the product and heating sides (for example for the simulation of mechanical vapor recompression) – ATEX proven
  • Mobile 1-effect falling film evaporator mainly for determination of long time behaviour (fouling and CIP procedure) – ATEX proven
  • Mobile Forced circulation evaporator with positive displacement pumps for very high viscosities – ATEX proven
  • Stationary forced circulation evaporator with centrifugal circulation pump
  • Mobile EVA evaporation system heated by heat pump

Combination of above stated systems and arrangements of process lines consisting of different technologies (e.g. membrane filtration, distillation, evaporation, centrifuge, decanter, dryer, etc.).
