Industry Segments We Serve

Automotive & Auto-Ancillary Manufacturing

The automotive manufacturing corridor spanning Oragadam and Sriperumbudur is one of India’s most advanced auto hubs, housing OEMs, Tier-1, and Tier-2 suppliers. Thermal imaging plays a vital role here in R&D validation, prototype testing, and quality assurance. Engineers use thermal cameras to study heat dissipation in braking systems, battery packs, power electronics, and exhaust components under simulated operating conditions. In vehicle interiors, thermal imaging helps validate heated seats, defoggers, and HVAC systems to ensure passenger comfort and uniform temperature distribution. Accurate calibration is critical because even minor measurement errors can distort thermal profiles, leading to incorrect design conclusions or QA rejections. In production environments, calibrated thermal cameras are also used for predictive maintenance of robotic welding systems, motors, and conveyors. Reliable thermal data ensures compliance with OEM specifications, reduces rework, and supports consistent product performance across high-volume manufacturing lines.

Electrical Transmission & Power Distribution (Thirumudivakkam & Gummidipoondi)

The electrical substations and transmission infrastructure in Thirumudivakkam and Gummidipoondi form the backbone of power supply for Chennai’s industrial ecosystem. Thermal imaging is the primary preventive maintenance tool used by utilities to identify abnormal heating in high-voltage insulators, busbars, transformer windings, and switchgear—often while equipment remains energized. These “hot spots” are early indicators of loose connections, insulation breakdown, or load imbalance. However, the effectiveness of such inspections depends entirely on the accuracy of the thermal camera. An uncalibrated device may underestimate temperatures, allowing critical faults to go undetected until catastrophic failure occurs. Proper calibration ensures accurate Delta-T analysis, enabling maintenance teams to classify fault severity and prioritize interventions. In power utilities, calibrated thermal imaging directly contributes to fire prevention, reduced outages, improved grid reliability, and enhanced personnel safety.

Pharmaceuticals & Biotechnology (Alathur & Chengalpattu)

For power utility companies and private contractors maintaining substations in Palladam and Pollachi, thermal imaging is the primary line of defense against grid failure. High-voltage switchyards, transformers, and capacitor banks develop "hot spots" due to loose connections, oxidation, or load imbalances. These hot spots are precursors to arc flashes and explosions. A thermal camera used for these inspections must be calibrated to quantify the severity of the fault. A "Delta-T" (temperature difference) of 5°C might be a "monitor" status, while 20°C is an "immediate repair." If the camera is out of calibration, a critical 30°C rise might be under-reported as 10°C, leading the maintenance team to ignore a dangerous fault. Vega’s NABL-accredited calibration ensures that your safety audits are based on precise, defensible data, protecting both infrastructure and personnel.

Facility Management & Green Buildings (Sholinganallur & Velachery)

With the rapid growth of IT parks and commercial complexes in Sholinganallur and Velachery, facility managers increasingly rely on thermal imaging for energy efficiency and sustainability initiatives. Calibrated thermal cameras are used to conduct energy audits by identifying air-conditioning leaks, thermal bridges, poor insulation, and moisture ingress within building envelopes. These hidden inefficiencies often lead to higher energy consumption, occupant discomfort, and long-term structural issues. Thermal imaging allows non-invasive inspection of façades, rooftops, electrical panels, and HVAC systems during normal operation. Calibration is essential to ensure accurate detection of small temperature differentials that indicate energy loss or condensation risk. Reliable thermal data helps facilities meet LEED and green building certification requirements, optimize HVAC performance, reduce operating costs, and improve occupant comfort while supporting sustainability goals.

Industrial Use Cases

Electrical Panel & Switchgear Inspection

In the high-demand industrial sectors of Maraimalai Nagar, electrical maintenance is critical. Thermal imaging cameras are used to scan vast banks of electrical panels, busbars, and circuit breakers to identify loose connections, unbalanced loads, or corroded contacts. A loose connection increases resistance, which generates heat—a precursor to an electrical fire. However, if the thermal camera is uncalibrated, it may report a critical temperature of 90°C as a safe 60°C, leading the maintenance team to ignore a ticking time bomb. Conversely, a high reading caused by reflection (rather than true heat) might trigger unnecessary and costly shutdowns. Vega’s calibration ensures that your camera correctly interprets emissivity and reflected apparent temperature, allowing safety officers in Hosur and Kanchipuram to distinguish between a false alarm and a critical emergency, thereby saving millions in potential fire damage and downtime.

Predictive Maintenance of Mechanical Motors

Manufacturing units in Thiruvallur utilize thousands of motors, pumps, and conveyor systems. Thermal imaging is the frontline tool for "Predictive Maintenance" (PdM). Technicians scan motor casings to detect overheating bearings, misalignment, or winding issues before the motor burns out. A calibrated camera allows them to trend temperature data over time—for example, noticing that a pump in Sriperumbudur is running 5°C hotter this month than last month. This specific trend analysis requires high repeatability and accuracy. If the camera’s calibration has drifted, the data becomes useless, leading to either "run-to-failure" scenarios or premature replacement of healthy parts. Vega’s NABL-accredited services validate the linearity of the camera’s detector, ensuring that a 5°C rise on the screen truly represents a physical change in the machinery, enabling precise intervention schedules that maximize asset life.

Process Quality Control in Injection Molding

For the plastic and polymer industries in Guindy and Ambattur, temperature control is synonymous with product quality. Thermal imaging cameras verify the temperature distribution across injection molds and extruded parts. If a mold has uneven heating, the resulting plastic parts will suffer from warping, internal stress, or incomplete curing. A thermal camera helps engineers visualize these thermal gradients instantly. However, different plastics have different emissivity values (ability to emit infrared energy). A camera that is not calibrated for these specific ranges can give wildly inaccurate readings, leading to batch rejections. Vega Calibrations validates the camera’s performance against variable blackbody sources, ensuring that quality managers can trust the thermal profile of their molds, reducing scrap rates and ensuring that automotive components made in Oragadam meet strict dimensional tolerances.

Process Temperature Profiling (Plastics & Rubber)

As energy costs rise, industries and commercial complexes in Chromepet and Taramani are turning to thermal imaging for building diagnostics. This use case involves scanning the building envelope to find "thermal bridges"—areas where heat is escaping in winter or entering in summer due to poor insulation or construction defects. It also detects hidden moisture trapped in roofs or walls, which appears cooler due to evaporative cooling. This is crucial for preventing mold growth and structural damage. An uncalibrated camera might miss the subtle temperature contrast required to spot a damp patch behind a drywall or a gap in window sealing. Vega’s calibration services ensure the camera’s thermal sensitivity (NETD) is functioning correctly, providing auditors with the confidence to sign off on green building certifications and energy-saving retrofits across the city.

Compliance & Audit Requirements

In industrially advanced landscape, data integrity for temperature measurement is the key to passing inspections:

• ISO/IEC 17025:2017: The global standard for testing and calibration laboratories. Our accreditation proves that we are technically competent to generate valid results.

• IATF 16949 (Automotive): Requires all external labs used by automotive suppliers (like those in Oragadam) to be accredited to ISO 17025 to ensure measurement traceability.

• FDA 21 CFR & GMP (Pharma): For pharmaceutical clients in Chengalpattu, instrument accuracy is tied to patient safety. Calibration records must be traceable and retrievable for regulatory inspections.
