The answers below are calculated with the LULL & STORM Stuffing Desk. A refrigerated unit is smaller inside than its dry equivalent, because of the insulation and the refrigeration unit. For pallets, the tool allows 2 cm of clearance per pallet.
Indicative figures based on typical dimensions. Always confirm with your carrier before loading.

How many pallets fit in a 20ft reefer container?
10 EUR pallets.

A 20' reefer measures about 5.44 × 2.29 m inside, against 5.90 × 2.35 m for a 20' dry: one pallet less. Do not load above the red load line, and leave air free to circulate under and above the cargo.

How many frozen cartons fit in a 40' reefer?
1,640 cartons of 18 kg (50 × 30 × 25 cm), or 29.5 t: the payload is reached.

With dense cargo such as frozen goods, weight is the limit before volume. The 40' high cube reefer offers about 11.58 × 2.29 × 2.55 m and a typical payload of 29.5 t, which varies with the manufacturer and the refrigeration unit.
