Our unique and patented 'CEM' technology, which stands for Controlled Evaporation Mixing, is developed for accurate vapour flow control. Traditional bubbler systems are often not capable of handling sufficient quantities of liquid with a low vapour pressure, or perform in an imperfect way. Moreover, they cannot instantaneously provide vapour of a mixture of liquids with different vapour pressures. These issues are overcome with our vapour delivery solutions.
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 1-1200 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
very stable vapour flow
flexible selection of gas/liquid ratio
lower working temperature than conventional systems
optional control by PC/PLC (RS232/fieldbus)
VDM-Series: Vapour Delivery Modules
Based on the CEM-technology as described above, we designed a new series of Vapour Delivery Modules. These compact sub-systems incorporate the components of the CEM-System and more! Besides gas and liquid flow controllers and the temperature controlled evaporator, the VDM-Series feature integrated power supply with display (1.8” TFT) and control functions.
No need for engineering or manufacturing
Pre-tested, safe and ready to use
Readout/Control panel, incl. 1,8” TFT display, alarm/signaling and counter functions.
