Challenge

Heat exchangers are critical components used across industries. Due to complex geometries, multiple inlet/outlet positions & tight tolerance requirements, traditional inspection methods were proving inefficient and error-prone. Key challenges included: Difficulty in accurately measuring complex geometries and spatial relationships. Time-consuming manual inspections impacting production timelines. Inconsistent accuracy and lack of traceable digital inspection data. High cost and inflexibility of conventional fixed CMM systems. On-site inspection limitations due to varying temperature, humidity, and industrial environments.

Solution

A portable 3D measurement and inspection solution was implemented. Using advanced handheld metrology technology, the solution enabled feature-based measurement of critical components such as: Inlet and outlet positions. Center distances between ports. External shell dimensions (length, width, height). Angular alignment between nozzles and shells. The system allowed operators to digitally probe key geometric features (planes, circles, axes) & align measurement data directly with CAD models. Integrated software enabled real-time data processing, coordinate system alignment, and instant generation of inspection reports. 

Results & Benefits 

Higher accuracy & repeatability in dimensional inspection of complex geometries. Significant reduction in inspection time. On-site inspection capability, eliminating production delays and rework. Digital traceability and automated reporting, enhancing quality control and compliance. Lower inspection costs by avoiding expensive fixed CMM systems and external services. By adopting OTS’s digital measurement solution, the client modernized its inspection workflow—achieving faster inspections, greater accuracy and improved overall operational efficiency
