HEXNOVAS WORKSHOPShell & Coil heat exchanger manufacturing
01 / 03Working principle
How the technology transfers heat.
One medium flows through the helical tube bundle while the second medium travels through the surrounding shell. The curved tube path provides a long heat-transfer length in a compact cylindrical body.
- Construction
- Welded tubular shell with internal helical tube bundle
- Typical media
- Water, glycol, steam and condensate
- Orientation
- Horizontal or vertical
- Connections
- Threaded, flanged, welded or customized
Engineering explained
