Why is the output a band?

Thermal behavior depends on load, insulation, ambient room conditions, and access patterns. A band is more honest than false precision.

What is the recheck interval?

It is the suggested monitoring interval during an outage based on estimated risk.

Runtime is a planning band. Validate against freezer model, load, ambient room conditions, and backup vendor specs.

When to use

Emergency planning
Backup sizing conversations
Facilities risk review

Do not use for

Validated disaster recovery without model-specific warm-up and backup-system testing

Door opens destroy margin

Opening a freezer during outage shortens passive protection and should be minimized.

Backup systems need drills

Runtime math should be validated by alarm tests, generator tests, and real escalation contacts.

Method

The estimate combines a passive warm-up band from freezer class, volume, ambient temperature, and access frequency with active backup capacity converted into hours by backup type. Output is a planning band, not a validated holdover claim.
