Reefer (Refrigerated) Trailer Fuel & Cost Calculator
Calculate auxiliary diesel fuel consumption and operational expenses for refrigerated trailers based on ambient weather, cargo temperature setpoints, and continuous vs cycle-sentry run modes.
Core Mathematical Formula: Reefer Burn Rate is determined by ambient-to-setpoint temperature delta (ΔT) and run mode (Continuous: 0.8–1.6 gal/hr; Start/Stop / Cycle Sentry: 0.35–0.75 gal/hr). Total Cost = Total Run Hours × Burn Rate × Diesel Price.
| Cargo Category | Setpoint | Mode | Burn Rate (gal/hr) | 24-Hr (Gallons) | Operational Notes |
|---|---|---|---|---|---|
| Deep Frozen (Ice Cream, Seafood) | -20°F to -10°F | Continuous | 1.10 – 1.65 | 26.4 – 39.6 | Requires high-speed continuous cooling; severe penalty in 90°F+ ambient heat. |
| Frozen Poultry, Beef & Pork | -5°F to 0°F | Start/Stop | 0.55 – 0.90 | 13.2 – 21.6 | Cycles off when setpoint is satisfied; saves 40–55% fuel vs continuous mode. |
| Fresh Berries, Lettuce & Leafy Greens | 34°F to 36°F | Continuous | 0.75 – 1.20 | 18.0 – 28.8 | Continuous airflow prevents respiration heat buildup, top-freezing, and spoilage. |
| Dairy, Milk, Eggs & Citrus | 38°F to 42°F | Start/Stop | 0.35 – 0.65 | 8.4 – 15.6 | Moderate tolerance allows cycle-sentry mode under mild ambient temperatures. |
| Chocolate, Candy & Pharmaceuticals | 55°F to 65°F | Continuous | 0.45 – 0.80 | 10.8 – 19.2 | Strict temperature uniformity required to prevent bloom or chemical denaturation. |
| Protect From Freeze (Winter Operations) | 40°F in <20°F Air | Heat Mode | 0.50 – 0.95 | 12.0 – 22.8 | Reefer runs hot-gas bypass or electric heat grids to prevent beverage cargo freezing. |
*Engineering benchmarks compiled across Tier 4 Final Thermo King Precedent (S-600/C-600) and Carrier Transicold (Vector 8500 / X4 7300) in 75°F (24°C) baseline ambient conditions. Subtract 20% in mild spring/fall; add 25–40% in 95°F+ (35°C+) extreme summer heatwaves.
Known for rapid pull-down capacity and proprietary Cycle-Sentry technology. Engine restarts dynamically to recharge reefer battery and circulate warm air when top-freezing risk arises. Burns ~0.35–0.50 gal/hr in Cycle-Sentry and ~0.85–1.40 gal/hr in Continuous mode.
Utilizes all-electric E-Drive architecture, eliminating belts, idlers, and compressor shaft seals. Provides up to 20% lower fuel consumption in electric standby grid mode. In diesel mode, burns ~0.40–0.60 gal/hr in Start/Stop and ~0.80–1.35 gal/hr continuous.
Protect your profit margins by emailing this addendum to your freight broker before signing the load rate confirmation:
Add this amount on top of standard dry van freight rates to recover auxiliary diesel costs when bidding refrigerated loads.

Canada NSC Standard 9: Max 13 hours driving within a 14-hour on-duty window, requiring 10 hours daily off-duty, operating under Cycle 1 (70h/7d) or Cycle 2 (120h/14d).
US EIA Benchmark: Tied to the weekly US Energy Information Administration national on-highway diesel index, billed in $/mile.
Canadian FCA / NRCan: Freight Carriers Association (FCA) of Canada weekly diesel rack pricing, pegged in Canadian cents per liter (cpl) and billed in $/km or % surcharge.
