PosiDrive Spiral®

PosiDrive Spiral® is an alternative to Lotension drive systems. PosiDrive Spiral features a stainless-steel grid belt with driving tabs on the inside edge. The tabs engage and are driven by vertical ribs on the spiral center drum.  PosiDrive Spiral is recommended particularly for applications where product movement is a problem, or where oils or other product characteristics cause operational issues with Lotension drive systems.

Features

The positive drive concept of the PosiDrive Spiral keeps belt tensions low which helps increase belt life and allows for increased product load capacity.

The PosiDrive Spiral system allows product dwell time to be easily set using a simplified single speed control and is offered for various cage configurations making it ideal for new spiral systems.

Features Include:

  • Engineered inside belt edge designed to securely engage ribbed cage
  • Simple to use, easy to adjust single point speed control system
  • Steel welded legs that reduce flexibility in the belt
  • Self-synchronizing drive eliminates flip-ups
  • Easily retrofittable options to minimize conversion downtime
  • Factory service support available 24 hours a day, 365 days a year

PosiDrive at a Glance:

  • Prevents product movement and disorientation
  • A perfect solution for oily products
  • Designed for processing both heavy and lightweight foods
  • Ideal for retrofitting existing proofing, cooling, and freezing spiral applications

NOTES:

  • UHMWPE material type components have a 150°F [66°C] maximum operating temperature.
  • Maximum bore sized listed for UHMWPE material is based on 1/2 inch [12.7 mm] of material above keyway.

FILLER ROLLS:

  • 4-3/16 inch [106 mm] diameter filler rolls recommended with #4-13 tooth sprockets
  • 5-7/8 inch [149 mm] diameter filler rolls recommended with #6-18 tooth sprockets
  • 7-5/8 inch [193 mm] diameter filler rolls recommended with #8-23 tooth sprockets

Supports

As a rule, support rails are required, with maximum spacings of 18 inches [457.2 mm] on the load side and 24 inches [609.9 mm] on the return side.  Rollers may also be used. For light loads, support rails may be placed farther apart - consult Ashworth Engineering for your particular application.

NOTES:

  • UHMWPE material type components have a 150°F [66°C] maximum operating temperature.
  • Maximum bore sized listed for UHMWPE material is based on 1/2 inch [12.7 mm] of material above keyway.
  • One sprocket will engage the inside row of links and one sprocket will engage the middle row of links.
  • One toothless flanged idler support roll supports the outside row of links.

FILLER ROLLS:

  • 4-3/16 inch [106 mm] diameter filler rolls recommended with #4-13 tooth sprockets
  • 5-7/8 inch [149 mm] diameter filler rolls recommended with #6-18 tooth sprockets
