Another innovative, patented technology

ThermoDrive belts are homogeneous
thermoplastic with 100 per cent closed
surfaces, making them well suited for
hygienic food-processing applications. At first
glance, they may appear to be traditional flat belts.
What makes them significantly better is the patented
ThermoDrive positive drive system.
Unlike traditional flat belts, these belts drive on
sprockets like a modular plastic belt and are not
under tension, enabling easy lifting for conveyor
cleaning and solving nearly all traditional flat belt
problems.
Intralox offer ThermoDrive technology for dough

including improving sanitation, extending belt life
and decreasing maintenance.
