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 1-1200 g/h H2O 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 vaporized successfully.
Mixing valves for evaporation purposes
Bronkhorst® mixing valves are usually supplied as an integral part of a Control Evaporator Mixer (CEM). They may also be supplied separately as a replacement part or for a particular set-up that does not require a heating chamber for complete evaporation of the liquid which is injected the carrier gas flow.
Mixing valve models W-001/W-002/W-003 have a pressure capability of 100 bar (1500 psi) and a purge connection for easy elimination of air or gas. They are directly operated by a magnetic coil with IP65 (weatherproof) housing and are closed when de-energized (Normally Closed).
