Davey Fanox Control Boxes for Borehole Pumps

Davey Fanox Control Boxes for Borehole Pumps

Davey Fanox Control Panels protect pumps against dry running without using level sensors or probes.

Protections:  Dry running, overload, overvoltage, phase loss, incorrect phase sequence on the CBT1, CBT2 and CBT5. Maximum protection without level electrodes or level relays.



 

APPLICATIONS

  • Protect borehole pumps against dry running without using level electrodes
  • Borehole Pump Control application
  • Can be used for surface pumps in some cases

 

WHY CHOOSE THE DAVEY Davey Fanox Protection Control Panels?

Davey’s Fanox Protection Control Panels offer a comprehensive solution for single and three-phase control and protection of submersible pumps in domestic, industrial
and agricultural installations.


Single phase panels  –  CBM2 & CBM3

Main Advantages:

  • Thermal memory that memorises heating and cooling cycles of the motor
  • Automatic reset, adjustable from 2 to 240 minutes
  • Indication of tripping cause
  • Control point for pressure switch, float switch, etc.
  • Includes: circuit breaker 1P+N, PS electronic relay, contactor, LED’s and on/off switch

Protection against:

  • Dry running by monitoring undercurrent
  • Overload with thermal memory
  • Overvoltage (+ 15%)
  • Short-circuit


Three phase models – CBT1, CBT2 & CBT5

Main Advantages:

  • Thermal memory that memorises heating and cooling cycles of the motor.
  • Automatic reset for well filling and adjustable from 2 to 75 minutes.
  • Indication of tripping cause.
  • Control point for pressure switch, float, switch, etc.
  • Includes: circuit breaker 3P or 3P+N, PF electronic relay, contactor, LED’s and on/off switch.

Protection against:

  • Dry running by monitoring cos φ
  • Overload with thermal memory
  • Phase loss/imbalance
  • Incorrect phase sequence
  • Short-circuit
