Professional Services

Electrical, Mechanical & Instrumentation (EMI) Engineering

We deliver integrated Electrical, Mechanical, and Instrumentation engineering solutions covering LV/MV/HV power systems, transformer substations, lighting and small power systems, instrumentation and control systems, power quality assessment, thermography, and energy optimization. Our services are designed to enhance safety, improve system reliability, ensure regulatory compliance, and extend the operational life of critical assets across residential, commercial, industrial, oil & gas, and critical infrastructure environments.

HVAC Systems Design, Installation & Maintenance

We provide complete HVAC solutions, including chilled water systems, VRF/VRV systems, precision cooling, automation, and preventive and corrective maintenance. Our approach ensures stable indoor comfort, improved energy efficiency, protection of sensitive equipment, and long-term operational performance for commercial, industrial, offshore, and critical facilities.

High Voltage Partial Discharge (PD) Testing & Monitoring

We offer advanced Partial Discharge (PD) testing and monitoring services for MV and HV electrical assets, including transformers, switchgear (GIS/AIS), cables, motors, generators, and associated equipment. Using online and offline diagnostic techniques, fault localization, and condition-based analytics, we help clients detect insulation weaknesses early, prevent unexpected failures, reduce downtime, and extend asset lifespan.
