The CEM-System (Controlled Evaporation and Mixing) is an innovativeLiquid Delivery System (LDS) that can be applied for atmospheric or vacuumprocesses. The vapor generation system consists of a (thermal or Coriolis) liquidflow controller, an MFC for carrier gas and a temperature controlled mixingand evaporation device. The system is suitable for mixing liquid flowsof 0,25-1200 g/h resulting in saturated vapor flows of 50 mln/minup to 100 ln/min. This vaporizer system can replace bubblers.New opportunities created with the CEM-system: mixtures can be evaporatedand even solids, dissolved in solvents can be vaporised successfully.
Based on the above CEM-technology as described above, Bronkhorst designeda new series of Vapor Delivery Modules. These compact sub-systems incorporatethe components of the CEM-System and more! Besides gas and liquid flowcontrollers and the temperature controlled evaporator, the VDM-Series featureintegrated power supply with display (1.8” TFT) and control functions.As an option, the unit offers local or remote trace heating temperaturecontrol.
The compact, ‘plug and work’ module can generate (saturated) vapor flowswithin the range of
100 mln/min up to 10 ln/min. It can be applied foratmospheric or vacuum processes and is capable of evaporating mixturesand even solids, dissolved in solvents.
