Case Studies

A sterile manufacturing plant in Gujarat experienced uneven airflow distribution causing room pressure fluctuations and contamination risks.

Complete TAB assessment using calibrated capture hoods and micro-manometers. Proportional balancing of 48 supply grilles and 12 return air grilles. Damper calibration and pressure cascade re-establishment.

• Stable differential pressure cascade (15 Pa sterile, 10 Pa prep, 5 Pa corridor)
• Zero pressure excursions over 30-day monitoring period
• Successful regulatory audit clearance

A pharmaceutical company in Hyderabad needed to qualify a new ISO Class 7 cleanroom facility for injectable manufacturing.

Executed complete DQ/IQ/OQ/PQ validation protocols. Performed HEPA integrity testing (PAO), non-viable particle counting, air velocity mapping, temperature/humidity uniformity, and airflow visualization studies.

• All test parameters within ISO 14644-1 limits
• Zero HEPA filter leaks detected
• Cleanroom recovery time under 15 minutes
• Complete validation dossier accepted by regulatory auditors

A large IT park in Pune with a 1000 TR chiller plant faced electricity costs 30% above industry benchmarks.

Conducted detailed HVAC energy audit measuring chiller COP, pump efficiency, AHU fan consumption, and cooling tower effectiveness. Recommended VFD installation on AHU fans, chiller tube descaling, and delta-T optimization.

• 22% reduction in annual HVAC electricity consumption
• Chiller COP improved from 4.6 to 5.3
• Payback period of 9 months
