double tube (DTA series)



The heat exchanger DTA series is a corrugated double tube heat exchanger specifically designed to meet the needs of the food industry, with high heat transfer levels. The product flows through the inner tube, and the service fluid flows between the inner and outer tubes. The corrugated surface of the inner tube increases heat exchange levels. The geometry of our DTA 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.


Recommended for the following products

  • Fluids containing fibres, dice, cells, and other solid 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.
