SPIRAL Heat Exchangers
AIC Spiral Heat Exchangers are custom crafted solutions for challenging, high-viscosity media. The unique circular chamber design, with two spiral channels, is ideal for sludges, slurries, waste water, wood pulps, high viscosity hydrocarbons, and fouling liquids containing fibers and solids.
Features and Benefits
- Single-channel design generates high shear rates, which contribute to a self-cleaning effect, preventing clogging of the unit. The perfect solution for challenging, high-viscosity media.
- The channel size is selected to fit the flow and qualities of the media. The many variations in diameters and widths of the spiral coil allow for many different combinations, creating the optimal solution for every duty.
- Designed to handle a very aggressive temperature program, and with a wide range of materials and plate thicknesses available, each spiral heat exchanger is customized to match the requirements of any application.
- Low product maintenance ensures extended operational uptime. Should the need arise, the hinged covers provide easy access to the entire heat transfer surface.
- Compact spiral design requires minimal operating space. The long, curved flow paths allow for heat transfer coefficients up to double that of a shell and tube equivalent.
