Robust & user-friendly
Protection from Damage & Downtime
Soft starts and stops protect your equipment. Reduced start currents result in smaller fuses, cables, and energy bills. Controlled stops eliminate the risk of water hammer and other costly damage.
A built-in shaft power monitor and a unique Load Curve Protection function protect your process by immediately detecting any situation that could cause inefficiency or damage. Early warning and safety stops allow preventative action.
Energy Savings & Optimized Operation
The FDU regulates flow and pressure by continuously adapting motor speed. No energy wasted and no unnecessary equipment wear. A sleep function further reduces energy consumption by pausing the motor when it does not need to run. An automatic pump rinsing function also increases efficiency.
Multiple pump or compressor control is a reliable and cost-efficient method of keeping a constant flow or pressure despite varying demands. The FDU can control up to seven pumps.
User-friendly & Reliable Operation
Operation parameters can be set in your own process unit - m3/min, bar, Pascal, etc. - making monitoring easier and more reliable. The removable control panel has a copy function for transferring settings to other FDU units. Switching between local and remote control can be accomplished with the push of a single key on the control panel. The virtual connection of logical functions, comparators, and timers, means no cables or external I/Os are required.
