Spiral DirectDrive™ (DD)
Series 2900Achieve superior product stability in freezing, cooling, proofing, and other spiral applications with our revolutionary DirectDrive technology.
Part of our advanced DirectDrive System, the S2900 Spiral DirectDrive belt engages directly with the drum, aligning and securing products from infeed to outfeed. This innovative design drastically reduces belt friction and eliminates overdrive to ensure reliable performance in all operating conditions.
- Lack of catchpoints minimizes harborage risks
