Typical Indirect Surface CondensersAs the name suggests, with indirect surface condensers the service side (cooling water) and the process sides are independent. With all indirect condenser steam ejector installations, steam nozzle jet impingement must be considered, to protect the inline equipment from steam droplet erosion. Indirect condensers are used when the Ejector fluid and cooling medium must be kept separate.
Benefits of Indirect Surface Condensers
- Steam condensate may be recovered
- Process product may be recovered as condensate, or gas at a higher pressure
- No contamination of condenser water can occur
- Vacuum surges will be less likely to carry water back to the process
- Less head room required
