Involved in improvements of the treatment of viscous or with particulates products, ACTINI SA has fitted its exchangers with tubes modified in geometry.
Specific geometries
• Corrugated
• Multilobe • Multitubulaire
Operating principle
•
In laminar flow (number of Reynolds < 2100), the heat exchange rates are far much lower than in a turbulent one.
•
The tubes with modified geometry have been designed in order to increase the global exchange rate and for a "core" treatment and homogenization.
•
In these tubes, the exchange surface is indeed higher in comparison with the volume of treated product.
Main assets
•
Improvement in the thermal efficiencies (up to 30%)
•
Treatment "in the middle" (no cold vein).
•
Geometries particularly appropriate to heat- sensitive products containing particules or very viscous.
•
Longer production period
•
Cleaning of the exchangers without dismounting it (design avoiding stagnant areas and preferential circuits, thus giving them perfect hygienic properties)
•
30% reduction of the machine size
