Low and high pressure Feeders are critical components of your fibre line. Their function is transporting chips and sawdust to steaming and digester vessels. Tristar rebuilds and manufactures most popular models and sizes of High & Low Pressure Feeders.

Each rebuild is

  • Photographed, disassembled and inspected
  • Evaluated to establish scope of work
  • Report issued to customer supported with N.D.T. reports
    and photographs

Tristar prepares a report with recommendations for feeder repair scope and a quotation with shipment date.
