Updating security signatures, firmware patches, and configuration audits to maintain robust network security and compliance. We conduct vulnerability scans and hardware health checks to prevent disruptions caused by security device failures.
Using advanced diagnostic tools to proactively detect performance degradation or component faults. Our technicians troubleshoot issues ranging from overheating and power irregularities to software conflicts and hardware failures.
Timely replacement of failing or end-of-life hardware components, including memory modules, power supplies, and cooling fans, to sustain optimal operational conditions. We also assist with hardware upgrades to support scaling and technology refresh cycles.
Detailed logs of maintenance activities, hardware status, and any changes implemented, ensuring transparency and enabling informed decision-making for future capacity planning and risk management.

Environmental Control Systems

Maintaining a stable and safe environment within data centers is critical to ensure the optimal performance and longevity of IT equipment. ERA GROUP provides comprehensive maintenance services for all key environmental control systems, focusing on reliability, efficiency, and compliance with industry standards.

HVAC Systems:

We perform both preventive and corrective maintenance on precision cooling units, including CRAC (Computer Room Air Conditioning) and CRAH (Computer Room Air Handling) units, chillers, and air handling systems. Our services include:
• Regular inspection and replacement of air filters to ensure clean air flow and reduce contamination.
• Airflow balancing and duct cleaning to maintain even temperature and humidity
distribution throughout the data center.
• Calibration and servicing of sensors and controls to optimize cooling efficiency.
• Leak detection and refrigerant management to comply with environmental
regulations and maintain system performance.
• Emergency repairs and parts replacement to prevent overheating and equipment
failure.
• Water tanks used in cooling systems or fire suppression receive routine cleaning, inspection for contamination, and maintenance to ensure safe, uninterrupted operation of auxiliary systems.
These efforts ensure that temperature and humidity are maintained within ASHRAE recommended limits, reducing thermal stress on critical infrastructure.

Building Management System (BMS)

ERA GROUP services integrated BMS platforms that centrally monitor and control HVAC, lighting, power distribution, and security systems within the facility. Our maintenance includes:
  • • Regular software updates and patches to improve system security and functionality.
  • • Calibration and testing of sensors and actuators to ensure accurate environmental readings and responsive control actions.
  • • Integration of alarms and notifications for early detection of system anomalies or failures.
  • • Data logging and reporting to support operational decisions and compliance audits. The BMS enables centralized facility management, helping reduce energy consumption and operational costs while improving reliability.

Fire Detection & Suppression Systems:

We provide detailed inspection, testing, and maintenance of advanced fire safety systems including:
  • • Early Warning Smoke Detection: Maintenance of Very Early Smoke Detection Apparatus (VESDA) systems that detect smoke at its earliest stages, allowing rapid response before fire escalation
  • • Conventional Smoke Detectors & Fire Alarms: Functional testing and battery replacements to ensure continuous protection.
  • • Gaseous Fire Suppression Systems: Servicing of clean agent systems such as FM200, Novec 1230, or inert gas agents, including cylinder pressure checks, nozzle inspections, and system discharge tests.
  • • Fire Panel & Control Equipment: Regular diagnostics and firmware updates to maintain system reliability and compliance with local fire codes. These systems are critical for safeguarding data center assets by rapidly detecting and suppressing fires without damaging sensitive electronic equipment.

Physical Security Systems

ERA GROUP ensures the security and protection of your data center and telecom facilities by maintaining advanced physical security systems designed to control access, monitor activities, and safeguard assets and personnel.

Access Control:

We maintain and service a variety of access control technologies including biometric scanners (fingerprint, facial recognition), RFID card readers, proximity sensors, turnstiles, and electronic locks. Our maintenance services cover hardware calibration, software updates, and system integration to ensure seamless operation. These systems restrict entry to authorized personnel only, enforce multi-factor authentication, and provide detailed access logs for audit and compliance purposes.

Video Surveillance (CCTV) :

ERA GROUP provides routine inspection, calibration, and preventive maintenance of high-resolution IP and analog CCTV cameras, including pan-tilt-zoom (PTZ) units, thermal cameras, and fixed lenses. Our services include lens cleaning, firmware updates, camera repositioning, and network video recorder (NVR) or digital video recorder (DVR) system upkeep. We ensure continuous recording, secure data storage, and effective video analytics integration (motion detection, facial recognition, anomaly detection) to enhance situational awareness and provide reliable evidence for security incidents.

Power System Maintenance

ERA GROUP provides specialized maintenance services for all critical power infrastructure components within data centers and telecom facilities, ensuring continuous, clean, and reliable power supply to prevent costly downtime and equipment damage.

Uninterruptible Power Supplies (UPS) & Battery Banks:

Our maintenance covers comprehensive capacity and performance testing of UPS systems, including battery health checks, replacement of aging or degraded batteries, and firmware updates to enhance system responsiveness. Thermal management practices such as temperature monitoring and cooling system maintenance prevent overheating and extend battery life. These services guarantee uninterrupted power delivery during utility outages or voltage fluctuations.

Diesel Generator Sets & Fuel Tanks

We perform thorough engine servicing including oil and coolant changes, filter replacements, and system diagnostics to maintain engine health and efficiency. Fuel polishing processes remove contaminants from diesel fuel to prevent injector clogging and fuel system failures. Scheduled cleaning and inspection of diesel fuel storage tanks ensure fuel quality and prevent sediment buildup, microbial growth, and corrosion. Leak detection and corrosion control measures safeguard environmental compliance and fuel integrity. Load bank testing simulates full-load conditions to verify generator performance and reliability, while synchronization checks ensure seamless parallel operation of multiple generator sets during power transfers.

Transformers & Electrical Distribution:

Maintenance of oil-immersed transformers includes regular oil sampling and filtration to remove moisture and impurities, insulation resistance testing, and thermal imaging to detect hotspots. Protective relay calibration and functional testing ensure reliable operation and fault detection. Dry-type transformers receive cleaning, insulation checks, and thermal performance evaluations to maintain voltage stability and power quality within the facility.
