Feature Overview
The control units run Biodynamic stirrers fitted with commonly available and affordable capacitor start capacitor run electric motors, both prototype and current model control units have been tested and working for many years with Fasco GP motors.
Existing or new float mechanisms are easily adapted to sense Biodynamic stirrer’s start/stop cycles however the switch is only required to carry low voltage and current resulting in a SAFE and low cost implementation.
There is no mains power required in direction change switches or float micro switch, but one of the most important aspects of this design:
There is also no arm, fin, or other obstruction required inside the stirrer for direction change.
From applications I have seen were there is a physical mechanism inside the stirrer, these systems effectively “sample the chaos” of the vortex, and pass that chaotic signal back to whatever control mechanism is in place driving the motor – the effect is often erratic starting and stopping stir cycles and direction change, and dramatically increased stress on motor.
With the recommended float mechanism and the control units you do not sample the chaos of the vortex – instead computer logic in the control unit takes care of motor direction and stirrer cycles including 60 minute countdown for each stir.
The float mechanism provides a smooth signal which changes throughout the 60 minute stir as the work in water changes, it sends accurate information to the control unit when each cycle should stop at the height of the vortex.
There is no need for external power timers to run the complete 60 minute stir cycle, and the computer also counts up after the stir has finished so you know exactly when the cycle finished and how long you have left to get it out into the paddock.
Control Unit V2 (1HP) are available dependant on stock of components and build time requirements.
Control Unit V2 (2HP) are currently under development..
Control Unit VERSION 3 is at design stage and further development may proceed in the future..
