Resistance for electrolytic starters


This type of starter enables high-end starting, while reducing the cost of high-power starting.
When starting, the starter's power and impedance are varied by adjusting the electrodes in an electrolytic bath. The more the electrodes are immersed, the more power they deliver.


  • Energy saving
  • Reliable
  • Resistant to tropical and corrosive atmospheres
  • Economical
  • High power ratings
  • Adaptable starting curve
  • Wide range of settings.
  • IP54
  • No heat generation

Compliance with standards

A safe investment

This type of starter is easily adapted to the motor. In the event of a motor change or process modification, a simple adjustment enables you to retain the electrolytic starter and save costs.



The EP range of "continuously variable" liquid starters is designed for starting high-power slip-ring motors. The starter consists of :

  • A tank containing the electrolyte
  • A mechanism that controls electrode movement
  • A MV box containing the short-circuiting contactor
  • A B.T. control equipment box

Innovative technology and Internet connection

  • Degree of protection for tank and enclosure "IP54″.
  • Noble, durable assembly Maintenance-free stainless steel - bronze - PTFE
  • Intelligent sequencer (optional) for all automation, safety and special functions:
  • Recording start-up curves on PC
  • Constant current starting
  • TCP/IP and Internet connection, etc.


The ARL starter, based on the intrinsic characteristics of electrolytes, offers decreasing resistance to current flow. Its electrolytic resistance, always in the liquid phase, ensures remarkable starting performance. Depending on application and motor power, 2-stroke or 3-stroke systems are available. At the end of starting, the short-circuiting contactor eliminates the starter.


The variable-level CRN starter consists of two parallel resistors. The first is set to provide starting torque and absorb most of the energy (80%). The second resistor is activated during the last phase of starting, when the motor has reached 60-80% of its speed. The pump gradually fills the upper tank. The resistance decreases continuously, ensuring that the motor speeds up to rated speed.
At the end of start-up, the short-circuiting contactor eliminates the starter.
