Vacuum evaporator CEM-System

processfor liquids

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 1-1200 g/h 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 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)
