Welcome To Nexus
Nexus Mapping Solutions, LLC is a San Diego CQV consultancy providing fixed-price, risk-based temperature qualification for cold rooms, warehouses, CTUs, reefers, and lab equipment, delivering calibrated data and inspection-ready documentation.
Fixed Pricing
Clear scope, fixed fees, and published assumptions remove surprise change orders and make internal budgeting and approvals faster and less stressful.
Risk-based designs, aligned with ISPE and USP guidance, focus testing on credible worst cases and generate qualification evidence that stands up to inspection.

2. Map the Environment
Deploy calibrated loggers throughout the usable product-storage volume.
3. Test Real Use
Add loaded PQ when load configuration, airflow disruption, thermal mass, or operations may affect performance.
4. Document & Monitor
Deliver the report and recommend permanent monitoring locations.

Why Mapping Matters
Temperature setpoint is not the same as product-storage conditions. Mapping identifies temperature variation throughout the usable storage volume, including potential hot, cold, poorly circulated, or operationally affected locations.
