The Bronkhorst unique Controlled Evaporation Mixing technology (CEM) is developed for
accurate vapor flow control. Traditional bubbler systems are often not
capable of handling sufficient quantities of liquid with low vapor pressure
or perform in an imperfect way. Moreover, they cannot instantaneously
provide vapor of a mixture of liquids with different vapor pressures.
The evaporator is combined with Bronkhorst liquid and Gas Mass flow instruments customised for your unique application
Components of a CEM-system
A complete CEM system incorporates a carrier gas flow controller, a liquid
flow meter, a 3-way mixing valve in which the liquid is injected into the
carrier gas stream, a heat exchanger in which total evaporation is achieved,
and a readout/control unit including power supply, for operation of the gas
flow, liquid flow and temperature.
