Mathematical Formula Breakdown
Reefer Burn Rate is determined by ambient-to-setpoint temperature delta (ΔT) and run mode (Continuous: 0.8–1.5 gal/hr; Start/Stop: 0.35–0.75 gal/hr). Total Cost = Hours × Burn Rate × Diesel Price.

All calculations execute strictly according to standard federal transportation benchmarks and transparent mathematical constants with zero hidden padding.

Hauling Frozen Meat in Summer Heat

Hauling a load of ice cream set at -10°F in 95°F summer heat (ΔT = 105°F) over a 36-hour transit using Continuous mode. Diesel is $3.90/gallon.

Extreme temperature differential and continuous airflow requires ~1.25 gallons of diesel per hour. Total fuel consumed = 36 hours × 1.25 gal/hr = 45.0 gallons. Total reefer fuel expense = 45.0 × $3.90 = $175.50. You must ensure your freight rate includes at least a $0.25 to $0.35/mile cold-chain surcharge.

Fresh produce, flowers, chocolate, and sensitive pharmaceuticals typically mandate Continuous run to maintain consistent air circulation and prevent top-freezing or hot spots. Frozen freight (such as poultry or ice cream) can often safely utilize Start/Stop once pre-cooled.
