Variable Speed Drive Triol AK06

Variable Speed Drive (VSD) AK06 series is designed to control and protect electric submersible and surface pumps with induction and permanent magnet motors. Triol AK06 VSD solution combines unique technical characteristics, the highest operating qualities, and excellent reliability.

Triol AK06 VSD is represented by 6 lines, each of which was created for definite segment of the global oil production industry. The lines differ from each other in the cabinet enclosure type and the power requirements at the VSD input. Variable Speed Drives AK06 series is the optimal solution to a wide range of operational tasks, significantly save the time of service engineers.

The dedicated special algorithms of VSDs operational system strengthen resources of oil production Companies and contribute to the growth of oil industry. Triol AK06 VSDs correspond to virtually any task of ESP technology and help oil and oilfield service companies receive the maximum benefit.

The products of the series operate in the following climatic conditions:

  • Arctic
  • Tropical
  • Desert
  • Maritime (including offshore platforms)
