The spiral heat exchangers are compact and ideal for many HVAC and industrial applications.

Operation of the spiral heat exchanger:
The hot fluid enters at the center of the unit and flows from the inside outward. The cold fluids enter at the periphery and flows towards the center. Thus, true counter current is achieved.

Application Range of Spiral Heat Exchanger:

  Minimum Max

Nickel Alloy, C-276 , Titanium

Typical Spiral Heat Exchanger Configurations:
Spiral Liquid-Liquid
Typical counter-current flow for both liquids.

Spiral Gas Condenser
Typical chamber on top of heat transfer bundle and gravity flow as it condenses or cools.

Spiral Liquid Vaporizer
Typical reboiler configuration with vapour dome on top of the heat transfer bundle.

Spiral Vapour Condenser
Typical vapour condenser, usually with little or no inerts.

Spiral Top Condenser
Typical condenser without cover and is usually installed directly to column or reactor.

Common Spiral Heat Exchanger Applications Include:
1. PVC slurries
2. Particle laden/fibrous media in ethanol, textiles, pulp and paper etc.
3. Erosive slurries metal extraction and processing
4. Hydrocarbon processing
5. Viscous fluids such as heavy oils and oil extraction
6. Distillation, condensation and reboilers
7. Vegetable oil deodorizing
8. Non-Newtonian fluids
9. Sewage sludge and waste water
