A spiral heat exchanger is a compact heat transfer device that uses two long metal sheets coiled into concentric spiral channels, allowing two fluids to flow in counter-current paths. Its single-channel design creates high turbulence and a self-cleaning effect, making it ideal for fouling fluids, slurries, and viscous media.
Thermocare Boilers Pvt Ltd (TBPL) designs and manufactures high-efficiency engineered to your exact process conditions. With over 25 years of experience in industrial heating and cooling, we supply rugged, space-saving spiral units to pharmaceutical, chemical, food, textile, paper, and wastewater plants across India and overseas.
A spiral heat exchanger (also called a spiral plate heat exchanger) is built from two coiled metal plates that form two continuous, curved channels wrapped around a central core. One fluid flows through the first channel while the second fluid flows counter-currently through the other, transferring heat across the plate wall.
Because each fluid travels through a single, uninterrupted passage, the design generates high velocity and high shear rates. This turbulence scours the channel walls, producing a self-cleaning action that resists clogging the key reason spiral units outperform conventional exchangers when handling difficult, particle-laden, or high-viscosity fluids.

The curved flow path forces continuous directional change, increasing turbulence even at low flow rates. This delivers heat transfer coefficients up to twice as high as a comparable shell and tube heat exchanger, while the compact spiral geometry occupies as little as 30% of the floor space of an equivalent tubular unit.
A single-channel design that produces high shear rates and a self-cleaning effect to prevent clogging. Channel width and spiral diameter are matched to your flow rate and fluid properties, making this type the preferred solution for high-viscosity media, sludges, and fouling liquids. Hinged covers on both sides open fully for fast inspection and cleaning, maximising uptime.
A sturdy, compact, fully welded unit built for solvent condensing and process heating/cooling. Used widely in solvent recovery, it achieves condensing efficiency above 95% with cross-flow vapour entering from the top and condensate collected at the bottom. In vacuum duty it delivers a lower pressure drop on the solvent side, and in multipurpose distillation plants it provides a high-performance condenser in a fraction of the space.
