CEM-Technology: Controlled Evaporation Mixing

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 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.

VDM-Series:
Vapor Delivery Modules

Based on the above CEM-technology as described above, Bronkhorst designed
a new series of Vapor 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.
As an option, the unit offers local or remote trace heating temperature
control.
The compact, ‘plug and work’ module can generate (saturated) vapor flows
within the range of
100 ml_n/min up to 10 l_n/min. It can be applied for
atmospheric or vacuum processes and is capable of evaporating mixtures
and even solids, dissolved in solvents.

Bronkhorst’s evaporation technology is fast, accurate, highly repeatable
and efficient.
