SpiralTrac™ for Pulp & Paper Refiners

Reduce your flush by 60% or more (depending on application), and extend the life of your packing in your Pulp & Paper Refiners with the Packing Version SpiralTrac

Refiner SpiralTrac Bulletin header image


By design, the Packing Version SpiralTrac™ enables greatly reduced flush through enhanced utilization of the flow and centrifugal effects around the rotating shaft. The SpiralTrac active throat bushing helps preventing fibre accumulation, which is a common cause of premature shaft and sleeve wear in Pulp & Paper applications. Installed and used in refiners across the Globe, the SpiralTrac Environmental Controller is the proven solution to maximize your equipment’s life and potential.
