​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​The SpiralTrac® Environmental Controller* is an exclusive, patented throat bushing specially engineered to transform and control the internal stuffing box environment in rotating process equipment to reduce downtime and extend equipment life. With unique versions designed to work with both Chesterton mechanical seals and packing, SpiralTrac modifies the flows that exist inside rotating processing equipment:
​
Enables particulates to be removed from the stuffing box (and away from packing or mechanical seals)
Permits air to evacuate the stuffing box upon flooding to retain cooling
Minimizes heat buildup in the stuffing box by creating circulation around
seal faces.​
