What are the interior dimensions of a 53ft reefer trailer?

A standard 53ft reefer trailer has interior dimensions of approximately 15,849 mm (52 ft) length × 2,464 mm (97 in) width × 2,591 mm (102 in) height. These are smaller than a 53ft dry van because the insulation walls and floor reduce usable space on all sides.

How many pallets fit in a 53ft reefer trailer?

26 standard GMA pallets (48 × 40 in / 1,219 × 1,016 mm) in the conventional orientation (48 in running along the trailer length, 2 wide). If pallets are turned 90°, up to 30 can fit. Euro pallets (800 × 1,200 mm) also fit 26 floor positions.

What is the maximum payload of a 53ft reefer trailer?

Approximately 18,500 kg (~40,800 lbs) under FMCSA 80,000 lb GVW. The reefer unit itself weighs roughly 1,800 kg (~4,000 lbs) more than a dry van body, which directly reduces available payload. The practical freight payload is typically 40,000–44,000 lbs depending on tractor tare.

How does a 53ft reefer compare to a 53ft dry van?

The reefer is shorter (15,849 mm vs 16,154 mm interior), narrower (2,464 mm vs 2,591 mm), and lower (2,591 mm vs 2,743 mm) due to insulation. It carries about 1,500–2,000 kg less payload. The dry van fits 30 GMA pallets vs 26 for the reefer. The trade-off is temperature control from -29°C to +21°C.

What temperature range does a 53ft reefer maintain?

A standard diesel-powered reefer unit (Thermo King X4 or Carrier Vector) maintains -20°F to +70°F (-29°C to +21°C). Multi-temp trailers have a bulkhead dividing the trailer into two independently controlled zones. Pre-cooling the unit to target temperature before loading is essential — reefer units are designed to maintain, not pull down, temperature.

What are the FMCSA weight limits for a 53ft reefer?

Federal limits for a 5-axle combination: 80,000 lbs GVW, 12,000 lbs steer axle, 34,000 lbs tandem drive axles, 34,000 lbs tandem rear axles. Individual states may have lower limits. The federal bridge formula (Formula B) may further restrict axle group loads based on axle spacing.

Why is the reefer payload lower than a dry van?

The refrigeration unit (engine, compressor, evaporator) adds roughly 4,000 lbs (~1,800 kg) of tare weight compared to a plain box trailer. Combined with thicker insulation walls reducing volume, reefer trailers haul approximately 1,500–2,000 kg less freight than a 53ft dry van under the same 80,000 lb GVW limit.

Note: Insulation walls on a reefer trailer reduce all interior dimensions compared to a dry van of the same overall length. The 53ft reefer interior is typically 15,849 mm long (vs 16,154 mm for a dry van), 2,464 mm wide (vs 2,591 mm), and 2,591 mm tall (vs 2,743 mm). The refrigeration unit adds roughly 1,800 kg of tare weight, reducing available payload. Always verify dimensions and payload with your carrier.

Bridge formula: The federal bridge formula limits tandem axle groups based on axle spacing. For a standard 5-axle semi-trailer, the practical payload ceiling is roughly 40,000–44,000 lbs (~18,000–20,000 kg). The reefer unit adds ~4,000 lbs (~1,800 kg) of tare vs a dry van, reducing available payload accordingly.

Temperature & cold chain

The 53ft reefer is equipped with a diesel-powered refrigeration unit (Thermo King or Carrier) capable of maintaining temperatures from -20°F to +70°F (-29°C to +21°C). Pre-cooling the trailer to target temperature before loading is critical — the reefer unit maintains temperature, it does not pull it down quickly.
