Pre-cooling duration should be verified for the container model, starting condition, environment and loading plan. One universal time will not suit every dispatch.

Start with model instructions

Check the manual for the pre-cooling method and lid position. In a trial record ambient conditions, starting and pre-load interior readings, measurement point and elapsed time.

Confirm readiness by measurement

Compare loading conditions using the same container and measurement method. The product specification and site procedure set the target; do not assume readiness from air temperature or elapsed time alone. Add the result to the shift plan.
