Why Empty Mapping?
Empty mapping establishes the baseline temperature profile and airflow pattern. It helps identify where loaded operation, monitoring sensors, and operational controls need additional attention.

Airflow Disruption vs. Thermal Mass
An airflow-disruption study makes temperature effects visible quickly using a representative, low-thermal-mass load. A thermal-load study is appropriate when product mass, packaging, or recovery behavior is a defined quality risk.

Disclaimer
Client-Provided Test Load Disclaimer
The client is responsible for identifying, approving, staging, and maintaining the test load. Before deployment, the client approves a Load Definition Form specifying test objectives, dimensions, fill level, and thermal mass. Nexus documents and executes the study as defined.
Fixed-Price Condition
The fixed price applies to one contiguous zone, one temperature range, and one approved load configuration. Scope changes after protocol approval require written re-approval.
