1. PREVENTIVE MAINTENANCE & REGULAR INSPECTIONS

Preventive maintenance is crucial to extending equipment life and ensuring compliance with industry standards. Our service follows a systematic approach for thorough inspections, adjustments, and preventive repairs to mitigate potential failures. Key activities include:

  • Routine Electrical System Testing: Comprehensive testing of electrical panels, circuits, transformers, and distribution systems, ensuring compliance with NEC Article 110 for safe installation practices and IEC 60364 standards.
  • HVAC System Performance Checks: Regular calibration, refrigerant level checks, filter replacements, and coil cleaning to enhance efficiency and prolong HVAC system life. We follow ASHRAE (American Society of Heating, Refrigerating, and Air-Conditioning Engineers) guidelines and NEC standards for power management.
  •  Load Balancing & Voltage Stability Monitoring: Ensuring load is evenly distributed across phases to prevent system stress, as per NEC 210.19 standards on branch circuit load requirements, minimizing voltage drops and harmonics.
  • Safety Equipment & Grounding Checks: Testing and maintaining ground fault protection, insulation resistance, and grounding systems as per NEC 250 and IEC 60364-5-54 standards to avoid electrical shocks, arc flashes, and grounding issues.

2. PREDICTIVE MAINTENANCE & CONDITION MONITORING

We leverage predictive maintenance strategies to detect early warning signs of equipment wear and potential failures, minimizing downtime and unplanned maintenance costs. Predictive maintenance techniques include:

  • Thermographic Scanning (Infrared Inspections): Identifying hotspots and abnormal heat signatures in electrical components using thermal imaging, as per NFPA 70B standards for electrical maintenance
  •  Vibration Analysis for HVAC Equipment: Detecting misalignments, imbalances, and bearing issues in motors, fans, and compressors through vibration analysis, ensuring optimal performance and
    adherence to ISO 10816 standards.
  • Power Quality Analysis: Monitoring harmonic distortion, voltage sags, and transients in compliance with IEC 61000-4 standards for power quality, which helps in proactive resolution of issues
    affecting sensitive equipment.
  • Condition-Based Inspections of Mechanical Components: Assessing the condition of belts, pulleys, and bearings, scheduling replacements before failures occur.

3. CORRECTIVE MAINTENANCE & EMERGENCY REPAIRS

When unexpected issues arise, our AMC services provide immediate response and corrective maintenance to minimize disruption and restore functionality. Our team is skilled in handling emergency repairs for both electrical and HVAC systems, ensuring rapid response times. This includes:

  • Fault Diagnosis & Troubleshooting: Utilizing advanced diagnostic equipment to isolate and address faults in electrical and HVAC systems quickly and efficiently.
  •  Replacement of Worn-Out Components: Replacing capacitors, relays, contactors, and other high-wear components to restore system reliability. Components are selected to align with IEC 60947
    standards for low-voltage switchgear and control gear.
  •  Compressor and Motor Repairs: Addressing issues with HVAC compressors and motors to prevent costly replacements, following IEEE standards for motor maintenance and NEC guidelines for motor
    circuit protection (NEC Article 430).
  •  System Calibration & Optimization: Recalibrating HVAC controls and thermostats, adjusting voltage regulation settings, and restoring systems to optimal performance levels.

4. DOCUMENTATION & COMPLIANCE REPORTING

We maintain detailed records of all maintenance activities, ensuring transparency and compliance with regulatory requirements. Documentation includes:

  • Maintenance Logs & Compliance Reports: Comprehensive records of all inspections, repairs, and replacements conducted under NEC, IEC, and local standards.
  •  Energy Efficiency Reports: Annual reviews highlighting improvements in energy usage and identifying potential areas for additional savings, aligned with IEC 60364-8-1 standards for energy efficiency
    in electrical installations.
  •  Safety & Compliance Certifications: Providing certificates for periodic inspections and regulatory compliance to meet insurance and local authority requirements.
  •  Asset Lifecycle Analysis: Tracking the condition and performance of equipment to support capital planning and timely replacements, ensuring equipment reliability and efficiency.

5. SPARE PARTS MANAGEMENT & INVENTORY

OEM and Compliant Spares: Stocking original equipment manufacturer (OEM) or IEC-compliant components to ensure quality, durability, and compatibility with existing systems.

  •  Critical Spares Readiness: Maintaining an inventory of critical spares such as compressors, motors, relays, and contactors for HVAC and electrical systems, reducing the impact of unplanned outages.
  • Predictive Stocking Based on Usage Patterns: Using data from previous maintenance activities to anticipate parts needs and adjust inventory levels, improving repair turnaround times.
