HEXNOVAS Shell Coil Heat Exchanger (Spiral tube heat exchanger ) is a compact all-welded heat exchanger designed for heating, cooling and heat recovery applications where conventional shell and tube units are oversized and gasketed plate heat exchangers may not be preferred.

Built with an internal helical coil tube bundle inside a pressure shell, this design provides efficient heat transfer, compact footprint and stable mechanical reliability. The spiral coil geometry increases turbulence and heat transfer efficiency while maintaining a practical cylindrical structure suitable for industrial systems.

Key Features:
• Compact helical coil structure for high heat transfer area
• All-welded design without plate gaskets
• Suitable for steam-to-water heating
• Available in stainless steel or titanium
• Ideal for HVAC, district heating, marine, pool and industrial process duties
• Customizable connections, materials and pressure ratings

Applications:
• Steam heating systems
• Hot water generation
• Marine and seawater systems
• Swimming pool heating
• District heating substations
• Industrial heat recovery

HEXNOVAS provides custom thermal selection based on flow rate, temperature, pressure and installation requirements.
