Inspection Process
Strict Quality Control at Every Stage
Our multi-stage inspection process ensures that every component and every unit meets the highest industrial standards before delivery.
Raw Material Inspection
Every batch of steel, copper coils, aluminum fins, PVC fill media, and galvanized sheets is inspected upon arrival. We verify material certificates, check dimensions, and test surface quality before any material enters production.
Fabrication & Welding Inspection
During sheet metal fabrication and welding, our QC team performs in-process checks on weld seam integrity, dimensional accuracy, and structural alignment. Every joint is inspected for consistency and strength.
Coil Pressure Testing
All heat exchange coils undergo hydraulic pressure testing at 1.5x to 2x the rated working pressure. This ensures zero leakage and verifies the integrity of every coil circuit before assembly into the cooling tower.
Assembly & Component Check
During final assembly, every motor, fan, spray nozzle, PVC fill, and structural component is checked for correct installation, alignment, and secure fastening. Electrical connections are verified for safety compliance.
Final Inspection & Documentation
Before packaging, each unit receives a comprehensive final inspection covering appearance, dimensions, performance parameters, and labeling. Complete quality documentation, test reports, and certificates are prepared for shipment.
Performance Verification
Water Testing Experiments
Before shipment, every cooling tower undergoes a complete water circulation test to verify cooling performance, water distribution uniformity, and leak-free operation.
Leak-Free Verification
Full water circulation at rated flow to confirm zero leakage across all piping connections, basin joints, and coil circuits.
Spray Distribution Check
Water spray nozzles are tested for uniform coverage across the entire coil or fill surface, ensuring optimal heat transfer efficiency.
Performance Validation
Motor operation, fan vibration, and overall system performance are monitored and recorded to confirm compliance with design specifications.
International Standards
Certifications & Compliance
Our products comply with internationally recognized quality standards, giving our customers confidence in every unit we deliver.
