Durable AC VF Variable Frequency Drive Drilling Rig for Versatile Oilfield Applications

Product Description

Product Description

AC VF Drive Drilling Rig

Engineered for precision, power, and reliability, our AC variable frequency drive (DB) top drive systems redefine drilling efficiency across all terrains—from shallow wells to ultra-deep explorations.

The drilling rig is equipped with independent driller control room. The gas, electric and hydraulic control, drilling parameters and instrument displays can be arranged unitedly so that it can achieve logic control, monitoring and protection through PLC during the whole drilling. In the mean time, it can also achieve saving, printing and remote transmission of the data. Driller can accomplish all operations in the room which can improve the working environment and decrease the labour intensity of drillers.
