Pump Protection Panels
Fanox Control Panels protect pumps against dry running without using level sensors. Protections: Dry running, overload, overvoltage, phase loss, incorrect phase sequence. Max.protection without level elctrodes or level relays.
3 Phase Panels with Soft Starter – CBS
With progressive startup and shut-down are fitted with soft starters to prevent problems caused by water hammering or sudden start-up and shut-downs. Equipment with halogen-free wiring.
3 Phase Panels – CBT
The cosine of phi (cos φ) is the value of the cosine of the phase angle between the voltage and the intensity of the electrical current. This oscillates from a value slightly below 1 for a full load operating motor to almost 0 when it is dry running.
1 Phase Panels – CBM
One of the most critical situations in pump operation is dry running. In dry running situations a current decrease is detected. This reduction of consumed current is measured by the PS-R electronic relay fitted to the protection panel: When the preset undercurrent value is reached it switches the pump off.
