Our double-tube heat exchanger DTI series comprises an inner and outer tubes. The product flows through the inner tube, and the service fluid flows through the space between both tubes. The corrugated surface of the inner tube increases heat exchange levels. The geometry of our DTI series heat exchanger produces a real counter-current flow. It is further equipped with bellows or an expansion joint to balance out the differential expansion of the inner and outer tubes during functioning, thus considerably extending its lifespan.

• Fluids containing fibres or any other kind of particles.
• Non-Newtonian and medium-low viscosity fluids.

• Shortens heat treatment times.
• Reduces fouling.
• Reduces the weight and volume of the exchangers.
• Improves the quality of the end product.
• Decreases product loss during cleaning downtimes or product changeover.
