The CEM-System (Controlled Evaporation and Mixing) is an innovative Liquid Delivery System (LDS) that can be applied for atmospheric or vacuum processes. The vapor generation system consists of a (thermal or Coriolis) liquid flow controller, an MFC for carrier gas and a temperature controlled mixing and evaporation device. The system is suitable for mixing liquid flows of 0,25-1200 g/h resulting in saturated vapor flows of 50 mln/min up to 100 ln/min. This vaporizer system can replace bubblers. New opportunities created with the CEM-system: mixtures can be evaporated and even solids, dissolved in solvents can be vaporised successfully.


  • accurately controlled gas/liquid mixture
  • fast response
  • high reproduceability
  • very stable vapour flow
  • flexible selection of gas/liquid ratio
  • lower working temperature than conventional systems
  • optional control by PC/PLC (RS232/fieldbus)

Optimising processes and costs of your production plant means perfect tuning of all components. According to your specific requirements, we design and build complete single or multi-stage plants in various kinds of configurations, including thin film evaporators, short path evaporators and complete distillation column systems. Depending on the requirements, static evaporators may be used in upstream stages of thin film and short path evaporation systems. Falling film evaporators, forced circulation evaporators, natural circulation evaporators or rising film evaporators can significantly improve the efficiency of your complete system.
