The Streicher Frequency Converter Cabinet is the Streicher variable-frequency drive (VFD) control cabinet for VTA wiped-film distillation systems, providing adjustable-speed control of the wiper drive motor. By varying the motor frequency, the VFD enables optimization of wiper rotation speed for different feed viscosities and distillation targets, directly affecting film thickness and distillation efficiency. An OEM VTA electrical system component; consult Root Sciences for service and replacement.
