CEM EvaporatorW-202A

3-way Mixing Valve and Evaporator

Bronkhorst® model W-202A CEM 3-way Mixing Valve and Evaporator is suited for precise vapor flow delivery, composed by mixing up to 120 g/h H2O (320 g/h IPA) with max. 10 ln/min of carrier gas at operating pressures between vacuum and 100 bar. The temperature controlled mixing device is used in combination with  a (thermal or Coriolis) liquid flow meter and an MFC for carrier gas, together forming a Controlled Evaporation and Mixing (CEM) System.
