Frequently Asked Questions

Standard reefer units consume 0.5-1.5 gallons per hour depending on ambient temperature, cargo type, and unit efficiency. In continuous operation, this equals 12-36 gallons daily. Modern high-efficiency units with electric standby reduce consumption to 0.7-1.1 gallons/hour. Factors affecting consumption include: pre-cooling practices (20% impact), door opening frequency (15% impact), insulation quality (25% impact), and maintenance condition (30% impact). Optimized operations typically achieve 25-30% fuel reduction.

With proper maintenance, reefer trailers last 12-15 years, while refrigeration units typically need replacement after 7-10 years or 15,000-20,000 hours. Factors extending lifespan include: preventive maintenance programs (adds 3-4 years), quality components (2-3 years), proper operation (2 years), and climate conditions. Total lifecycle cost averages $250,000, but optimized operations reduce this by 40% through extended equipment life and lower operating costs. Best practice: plan unit replacement at 15,000 hours to prevent catastrophic failures.

Preventing cargo claims requires multiple strategies: continuous temperature monitoring with alerts (prevents 70% of claims), proper pre-cooling before loading (20% reduction), correct product placement for airflow (15% impact), and driver training on door discipline (25% reduction). Document everything: pre-trip inspections, temperature logs, loading photos, and seal numbers. Invest in redundant systems—backup power, dual temperature recorders, and emergency protocols. Average claim costs $45,000, but comprehensive prevention programs achieve 95% claim-free deliveries.

California Air Resources Board (CARB) mandates Ultra-Low Emission TRU standards. Requirements include: registration in ARBER system, compliance with model year standards, 7-year replacement cycles for older units, and annual reporting. Non-compliance fines start at $1,000/day per unit. Compliance strategies: upgrade to Tier 4 units, install electric standby systems, use alternative technologies like cryogenic cooling. Budget $15,000-20,000 per unit for upgrades. Many fleets achieve ROI through fuel savings and avoided fines within 24 months.

Calculate ROI by comparing current costs to optimized operations. Typical savings include: fuel reduction (25% = $8,500/year), maintenance savings (50% = $6,000/year), cargo claim prevention (85% = $13,000/year), extended equipment life (40% = $3,000/year), and reduced violations ($4,500/year). Total annual savings average $30,000 per unit. Investment required: monitoring systems ($2,000), training ($1,000), upgrades ($5,000-15,000). Most fleets achieve full ROI within 6-18 months, with 300-500% returns over equipment lifetime.
