The profile of a spiral is compact and fits in a smaller footprint than a shell and tube design. Since the tube bundle is coiled, space requirements for tube bundle removal are significantly reduced.
When exotic material is required, a spiral tube heat exchanger minimizes the material used since manifolds replace the channels, heads and tubesheets of a conventional shell and tube design. The shell side is usually smaller than a comparable shell and tube design and there are no requirements for tube supports or pass dividers.

Advantage:

• Optimal design for corrosive fluid/ gases
• Vapor condensing/gas stripping capabilities
• Highly resistant to thermal and hydraulic shock
• Numerous flow path and connection configurations
• Compact and lightweight; easy to install
