DualPac® 2211 Beats Out the Competition at Food Processing Plant


Chesterton products – Chesterton DualPac® Packing Technology


In an effort to achieve more reliable sealing of a potato steam peeler, this food plant tried installing multiple types of packing in the hopes of finding one that would last. With their best contender only lasting two months before failure, Chesterton recommended the Chesterton DualPac® 2211 Packing Technology, and the MTBF increased astronomically!

A food plant tried multiple types of packing (PTFE, graphite, reinforced corners, etc.) to achieve more reliable sealing of potato steam peeler. The best MTBF they were able to achieve with other packing was two months before catastrophic failure when the packings needed to be completely replaced. The customer’s goal was to increase MTBF and reduce maintenance costs.

Operating conditions: Frequent, rapid pressurization 0 – 19 bar (0 – 80 psi) and rapid decompression 19 – 0 bar (280 – 0 psi). Bi-directional equipment.

Temperature: 212°C (415°F) Speed:18 rpm
