Variable Frequency Drive Dispersers

Model DVF Dispersers
Post Mounted, Variable Speed, Heavy Duty
Now available with Vector Drive Controller

The DVF models are heavy duty, high speed Dispersers with standard output torque using high efficiency motors and variable frequency inverter for a state-of-the-art variable speed drive designed into a single set of belt power train, resulting in maximum power delivery to the high speed mixing blade, in lower power consumption, in precise speed adjustments, and in programmable mode for automatic operation based on time, speed, temperature, viscosity, etc.

Series 2072 are production models from 5 to 200 HP.
