About the LD-9 Reefer

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

Carries the same dual gross-weight rating as the dry LD-9, at 4,626 kg in a lower hold and 6,000 kg on a main deck. Internal volume is quoted at 9.6 m³ once the insulation is accounted for, against 10.8 m³ for the dry unit.

What it carries

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

How it is built

  • An insulated cool container on a P1P base.
  • The door is solid rather than canvas, as the insulated envelope requires.
  • 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.
