Key Field Service Capabilities
Comprehensive on-site electrical, mechanical, and predictive diagnostic services tailored for procurement officers and plant operations managers.
Predictive Maintenance (PdM)
Advanced diagnostic monitoring using multi-channel vibration analysis, infrared thermography, motor circuit analysis (MCA), and partial discharge testing to identify insulation breakdown and mechanical stress before failure occurs.
Equipment Rigging & Installation
Turnkey removal, rigging, transport, precision mounting, and final laser alignment for large Above-NEMA electric motors, vertical turbine pumps, and industrial generators across challenging plant environments.
On-Site Diagnostics & Inspection
Comprehensive root-cause failure analysis, electrical insulation resistance testing (HI-POT, Surge, Megger), borescope mechanical inspections, and field troubleshooting by veteran electrical engineers.
Field Rewinding & Re-Stacking
In-situ stator core re-stacking, high-voltage coil replacement, and field rewinding services performed under strict clean-room protocols, minimizing equipment removal and international freight expenses.
Laser Alignment & Field Balancing
Precision 3D optical laser shaft alignment, structural resonance testing, and multi-plane dynamic field balancing to eliminate harmful vibration, reducing bearing wear and operational power losses.
Outage & Emergency Recovery
Rapid emergency dispatch teams available 24/7/365 for planned turnarounds, scheduled plant outages, or unexpected catastrophic failures to restore continuous production with minimal lead time.
