We believe quality must be measurable, traceable and repeatable. Our assurance framework integrates ISO9001 quality management, CTI-compliant thermal performance evaluation, automated manufacturing processes and multi-stage inspections. This approach ensures that every tower leaving our factory provides consistent, verifiable performance—whether deployed in a steel plant, a petrochemical facility or a nuclear application.
Our full-process quality control follows a structured sequence designed to eliminate defects and guarantee consistency:
Quality Workflow：
Material Qualification – FRP resins, fiberglass, steel components and motors are tested upon arrival.
Precision Forming & Molding – Automated FRP lines ensure uniform curing and dimensional accuracy.
Component Verification – Critical items (fill, drift eliminators, fans, gearboxes) undergo targeted testing.
Assembly Checkpoints – Each assembly stage requires inspection approval before entering the next phase.
Performance Validation – Towers are test-assembled and assessed for fit, airflow pathways and load integrity.
Final QA Report – A complete digital record is generated for traceability.
Thermal Testing Capabilities
Cooling efficiency measurement
Hot/cold water temperature evaluation
Airflow distribution mapping
Noise and vibration monitoring
Drift loss detection
On-site portable testing for real projects
Our test platform complies with CTI standards and provides accurate, repeatable thermal performance data—ensuring that every cooling tower performs exactly as designed.
Meet sustainability, quality and productivity challenges with advanced equipment and solutions.
Every cooling tower manufactured by Dongjie is assigned a digital traceability code. This system links material batches, inspection results, assembly logs and performance test data into a single record that accompanies the product throughout its lifecycle.
Traceable Items Include:
Material batch information
QC inspection results
Assembly process documents
Thermal performance data
Final acceptance report
From structural integrity to thermal performance, Dongjie ensures that every cooling tower is validated by measurable engineering data. Our quality system is designed to deliver reliability today—and sustained performance for decades.
