Materials of Construction
Corrosion resistant Steam Ejectors can be constructed from exotic materials including PTFE, PVDF, Hastelloy, Graphite, Monel, etc. Indirect Contact Condensers are usually constructed from Graphite and Direct Contact Condensers from PTFE lined Carbon Steel or PVDF.
Direct Contact and Indirect Contact Condensers are available for either barometric or low level operation. Indirect or Surface Contact Condensers (typically graphite block) are used when the Ejector fluid and cooling medium must be kept separate, where as Direct Contact Condensers (Spray type PTFE lined) are used when complete mixing is acceptable.
