How many IBC tanks (1,000 L) fit in a 40ft reefer?
IBC tanks (1,000 L) of 1,200 × 1,000 × 1,160 mm (also called IBC totes, intermediate bulk containers) in a 40-foot high-cube refrigerated container (40RH) — inner dimensions 11,583 × 2,294 × 2,557 mm. Calculated by the Cubestow engine on 2026-09-08.
Upright, single layer (not stacked). 41% of the space used, 1 layer high, about 22,000 kg (76% of payload). Open this load in the 3D planner →

The answer in detail
A standard 1,000-litre IBC on its pallet base measures about 1,200 × 1,000 × 1,160 mm and weighs roughly 1,100 kg full. A full container of IBCs is limited by payload, not floor space — which the numbers here make obvious.
Inner length and width are reduced by the insulation and the machinery. Cargo must not block the airflow along the ceiling or the T-floor.
The simple grid estimate is 9 along the length × 2 across × 1 high = 18. The engine found 20 — 2 more than either uniform grid — by mixing orientations so that the leftover strip along the wall is used. The top view above shows the pattern.
Variants
| Loading rule | Fits | Layers | Volume used | Total weight |
|---|---|---|---|---|
| Upright, single layer (not stacked) (headline figure) | 20 | 1 | 41% | 22,000 kg (76% of payload) |
| IBCs stacked two high (permitted for many empty or rigid-caged IBCs) | 26 | 2 | 53% | 28,600 kg (99% of payload) |

Frequently asked
How many IBC tanks (1,000 L) fit in a 40ft reefer?
20 IBC tanks (1,000 L) of 1,200 × 1,000 × 1,160 mm fit in a 40ft reefer (inner dimensions 11,583 × 2,294 × 2,557 mm), upright, single layer (not stacked). That uses 41% of the 67.9 m³ available and weighs about 22,000 kg.
What are the inner dimensions of a 40ft reefer?
Typical inner dimensions are 11,583 mm long, 2,294 mm wide and 2,557 mm high (456.0 × 90.3 × 100.7 in), giving 67.9 m³ of space and a rated payload of about 29,000 kg. Individual units vary by a few centimetres, so check the actual box for tight loads.
How much does a full load of IBC tanks (1,000 L) weigh?
20 × 1,100 kg ≈ 22,000 kg, which is 76% of the 29,000 kg payload — so this load is limited by space, not weight.
How was this number calculated?
By running the Cubestow 3D load-planning engine on the exact dimensions above, allowing rotation on the floor plane only, no stacking and the container's payload limit, then re-validating the plan for overlaps, support and weight. Real loads leave room for dunnage, door clearance and uneven cartons, so treat the figure as the practical maximum.
