About the LD-29 Reefer
The refrigerated LD-29 — a contoured cool container on a P1P base, built to the RAU code.
The insulated counterpart of the dry AAU, with a solid door in place of canvas. Internal volume is 11.1 m³ and tare rises to 450 kg, the heaviest of the lower-hold reefers, on an unchanged six-tonne gross rating.
What it carries
How it is built
- Full-width insulated lower-hold unit angled at both ends — the refrigerated counterpart of the dry AAU.
- The door is solid rather than the canvas used on the dry version.
- Insulated panel walls, usually foam-cored, built onto a standard container base.
- A solid door with a sealing gasket in place of the canvas curtain used on dry units.
- Active units carry their own refrigeration machinery with battery or aircraft power; passive units hold temperature using stored coolant.
- Temperature monitoring throughout, and on active units a controller showing setpoint against actual.
Why it is used
- Holds a temperature range across the whole journey, including ground handling and tarmac waits — the points where an unprotected cold chain usually breaks.
- Uses the same aircraft positions and handling equipment as the equivalent dry unit.
- The standard choice for pharmaceuticals, vaccines and high-value perishables, where a temperature excursion destroys the cargo's value.
What to check before booking
- Insulation and machinery both eat internal volume compared with the dry equivalent.
- Tare weight is markedly higher, so revenue payload is lower.
- Active units need power or charging on the ground, and pre-cooling before the cargo goes in.
