O produkcie
Complete cabinet solution for oil production
Variable Frequency Drive Triol AT24 line RT is a premium solution for submersible and surface oil production pumps (including SRP and PCP) with metal housing with the possibility to install additional options inside the cabinet. Triol AT24 VFD line RT is a complete cabinet for placing the main and additional functionality in one place and is a universal drive that controls both SRP and PCP, while it is also used for other types of industrial equipment, such as HVAC systems, fans, compressors, etc.
Special algorithm for PCP
Triol AT24 VFD line RT and line SR are identical in functionality, but line RT is more versatile due to special algorithm for PCP: implementation of kinetic buffering algorithm that allows the drive to remain in operation during short-term (up to 0.5 sec) power supply failure and “catch on fly” mode for induction motor with the turbine rotation output.
Two versatile versions
It is possible to optionally install input and output filters inside Triol AT24 VFD line RT cabinet. Triol AT24 VFD line RT is available in two versions: with a removable wireless control graphic terminal with induction supply or with an intelligent well controller with a 3” touch screen (optional – 7” touch screen).
