Nol-Tec BBU & LIW Powder Handling System – Twin Tower, Dual Feeder, Dilute Phase Pneumatic Transfer

Machine Overview This Nol-Tec powder handling system is a dual-tower configuration supporting polyester powder transfer from bulk bag unloaders through surge hoppers, loss-in-weight feeders, and rotary valves into a dilute phase pneumatic line. Both systems are identical and operate independently with separate destinations. Designed for precise powder metering, the system integrates Brabender LIW feeders, Siemens-based PLC control, and full air and rotary valve interface.
