How the LD-9 Reefer is used

The refrigerated LD-9: an insulated cool container on a P1P base, built to the RAP code with a solid door.

It carries the same two gross ratings as the dry LD-9: 4,626 kg in a lower hold and 6,000 kg on a main deck. Inside volume is quoted at 9.6 m³ once the insulation is counted, against 10.8 m³ for the dry unit.

Cargo it usually takes

  • Pharmaceuticals
  • Fresh produce
  • Seafood
  • Chilled and frozen food
  • Cut flowers

How this family is arranged

  • An insulated cool container on a P1P base.
  • The door is solid, because the insulated shell needs a seal.
  • Insulated panel walls, usually with a foam core, sit on a standard container base.
  • A solid door with a sealing gasket takes the place of the canvas curtain used on dry units.
  • Active units carry their own refrigeration, on battery or aircraft power. Passive units hold temperature with stored coolant.
  • Temperature is watched throughout. On an active unit the controller shows the setpoint next to the actual temperature.

Why operators pick it

  • It holds a temperature band for the whole journey, including the ramp and the wait on the ground, which is where an unprotected cold chain usually fails.
  • It uses the same aircraft positions and the same handling gear as the matching dry unit.
  • It is the usual choice for pharmaceuticals, vaccines and high-value perishables, where a temperature spike ruins the cargo.

Settle these points before you book

  • Insulation and machinery both take inside volume compared with the dry unit.
  • Empty weight is much higher, so the paying payload is lower.
  • An active unit needs power or a charge on the ground, and pre-cooling before the cargo goes in.
