About product
Specially designed high-tech solution
Variable Frequency Drive Triol AT24 line SR is specially designed for high technological tasks of controlling sucker rod pumps (SRP) with induction motors. Implementing Triol AT24 VFD line SR there is no need to use a rod load sensor, thanks to Triol special algorithms, which allow getting dynamograms with a measurement error of less than 2%.
Automatic flow rate optimization
There is no need to use braking resistors due to drive automatic adaptation to the rod pumping speed. Rocking mill balancing control system and rocking mill mechanical part diagnostic system allows monitoring system status and perform maintenance in time. Automatic flow rate optimization makes it easy to maintain the rate at the optimal level by controlling the well dynamics. It is possible to optimize the process due to archives of dynamograms. The archived data is accessible over the years, whenever you need it.
Remote monitoring and control
Safe operation of Triol AT24 VFD line SR is ensured by blocking from unauthorized pump start and change of system key settings, as well as light and sound alerts for personnel before operation start. Remote monitoring and control via GSM-modem compatible with any application make it easy and convenient for maintenance personnel. It is possible to control the drive via satellite communication as well.
