FlexBox Smart Fuel-Saver Solution
Cut Fuel Costs. Optimize Power. Drive Sustainability.
At Power Intelligence Group, we partner with proven technologies that deliver measurable operational savings and a clear path to sustainability. FlexBox is a precision-engineered fuel-optimization device designed for reefer trailers and similar diesel generator applications—locking in efficiency gains while lowering operating expenses.
Why FlexBox Matters
Diesel fuel expense is one of the largest controllable costs for refrigerated transportation and fleet operations. FlexBox integrates advanced power-factor correction and energy-management technology to improve the efficiency of your reefer generator system.
01
Real-World Savings
Users can save up to ~3 gallons of diesel fuel per day on reefer units equipped with FlexBox. That translates into significant monthly and annual cost reductions.
02
Efficiency Where It Counts
FlexBox reduces wasted generator output by balancing electrical load, limiting excess fuel burn while maintaining cooling performance.
03
Sustainable Impact
Lower fuel consumption also means reduced greenhouse gas emissions, aligning with corporate sustainability goals and ESG reporting standards.
How It Works
FlexBox optimizes the electrical characteristics of your reefer’s power system by addressing inefficiencies in how diesel generators supply power. Generators with low power factor must produce excess apparent power to meet demand. FlexBox corrects this imbalance, allowing the generator to run closer to real power requirements, reducing fuel usage without compromising performance.
The Business Case
With diesel prices consistently elevated and budget pressures on logistics operators intensifying, FlexBox delivers:
Quantifiable Fuel Savings
Potential savings of up to $450/month or $5,400/year per trailer (based on average market fuel prices).
Scalable Impact
Savings scale with fleet size and utilization, improving ROI across your entire refrigerated transport operation.
Data-Driven Confidence
Third-party tests demonstrate measurable improvements in fuel economy and generator efficiency.
Engineered for Reliability
Developed by a team with two decades of experience in energy optimization and patented electrical technologies, FlexBox is built for rugged field conditions and dependable performance.
