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 ml_n/min up to 100 l_n/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.

Features:

• 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)

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.
• Integrated fieldbus interface (option)
