The brief

Our client needed to verify airflow performance through a controlled test, with the final results demonstrated during a witnessed assessment.

The project required a suitable test rig and thorough preparation to ensure the final test could produce reliable, meaningful results. Before the witnessed assessment, the setup needed to be checked and pre-tested to establish that it was ready for the formal demonstration.

What we did

Chillax Engineering managed the project from the initial test rig design through to the successful completion of the witnessed performance test.

Test rig design and setup
We designed and set up the test rig to support the required airflow performance assessment. This provided the foundation for both the preliminary checks and the final witnessed test.

Comprehensive pre-testing
Before the witnessed assessment, we carried out comprehensive pre-testing to check the setup and assess performance against the required criteria. This preparation was essential to ensure the final test was ready to proceed.

Witnessed performance testing
With preparation complete, Craig and Caitlin attended the final airflow performance witness test. The test demonstrated that the required performance criteria had been met, giving the client confidence in the results.

The outcome

The airflow performance witness test was completed successfully, providing our client with verified results against the required performance criteria.

By managing the process from test rig design through to the final witnessed assessment, Chillax Engineering provided continuity throughout the project. Thorough setup and pre-testing supported a successful final demonstration and gave the client clear evidence of airflow performance.
