HVAC Qualification Standards (DQ, IQ, OQ, PQ)

Rigorous validation documentation adhering to US FDA, WHO GMP, and ISO clean room compliance protocols.

DQ

Design Qualification

Verifying psychrometric calculations, CAD layouts, material compliance, and air change rate specifications before fabrication.

IQ

Installation Qualification

Auditing physical installation, duct seal integrity, HEPA filter integrity test (PAO/DOP), electrical wiring, and sensor placements.

OQ

Operation Qualification

Testing airflow velocity, room pressure differential, temperature/RH control loops, and alarm limits under static conditions.

PQ

Performance Qualification

Validating room air particle counts, thermal stability, and recovery time under full operating heat & personnel load.

Independent Third-Party Audits & TAB Commissioning

Comprehensive field measurement and certified balancing for guaranteed system performance.

Energy Audit

Detailed KW/TR benchmarking, thermal imaging, power factor analysis, and investment payback reporting.

HVAC Performance Audit

Evaluating chiller COP, AHU fan static pressure, cooling tower approach temperature, and piping pressure drops.

Clean Room Validation

ISO 14644 & EU GMP particle count tests, HEPA filter leak tests, airflow pattern visualization (smoke test).

EHS & ISO Audits

Environmental, Health, and Safety (EHS) compliance audits for indoor air quality and chemical refrigerant containment.

TAB Commissioning

Testing, Adjusting, and Balancing (TAB) for air, chilled water, and static pressure differential to eliminate hot spots.

Sensor Calibration

Precision calibration of temperature sensors, humidity transmitters, differential pressure gauges, and CO₂ monitors.

Energy Saving Retrofit Solutions

High-impact technologies designed to cut electricity bills from day one.

Automatic Tube Cleaning System

Keep condenser tubes 100% free of scale deposit automatically using sponge balls, improving chiller COP by 10-15% permanently.

Adiabatic Condenser Cooling

Pre-cooling ambient air entering air-cooled chillers during peak summer, reducing head pressure and peak KW draw by 18%.

EC Fan Retrofits

Replacing belt-driven AC fans in AHUs with direct-drive electronically commutated (EC) fans, saving 30%+ electricity.

Predictive Maintenance & VFDs

Dynamic VFD speed modulation driven by IoT differential temperature loop algorithms.
