What we have written on the cold chain12 / 154

A passive system runs no unit on the vehicle, yet it is not energy-free: plates are frozen at the depot and boxes are washed and returned. The comparison is made on the same delivery service.

Record product and box starting readings with separate times and methods; route pre-dispatch differences through the approved acceptance process.

Compare your loss rate with your own history, on the same base and the same return window, not with another company's figure. The same 12 lost containers can come out at 3% or at 4%, depending on the base.

Why forcing the lid costs more than the delay, how to check load height against the container's interior height and plate space, and what the road traffic law says about unsecured loads.

If damage and washing rise together, account for use intensity; compare per-cycle rates among containers of similar age.

Compare the same defined delivery service; show production, use, returns, maintenance and end-of-life in the boundary.

For the same service unit, record parts, labor, verification and remaining cycles; appearance or low price alone is not a decision.

Separate event times from arrival until cold-area entry to distinguish receiving delays from driving time.

State the return leg's system boundary and divide its attributed impact by empty units returned; distinguish shared and dedicated trips.

Use the same delivery service as the functional unit. Compare washing, returns, losses, materials and waste within the same period and system boundary.

Check rack arrangement against plate and freezer instructions. Record readiness and energy for the same batch to compare positions.

EPAL 1 and CHEP 03 share the same 800 × 1200 mm footprint but carry different load ratings. The container question is settled together with the pallet, the vehicle body and the door width.
