Auxiliary Power
& Idle Reduction
Auxiliary power, engineered
for your business
APUs and idle reduction technology cut unnecessary engine idling while keeping your cab powered — heating, cooling, and hotel loads included, without burning diesel to get them.
From assessment to operation —
one continuous partnership
Every idle reduction plan starts with the right fit
A Class 8 tractor can burn about a gallon of diesel for every hour it idles — accumulating to 2,000–3,000 hours a year per vehicle. Before recommending hardware, Velociti assesses your climate, vehicle types, and operational needs to find the right mix from seven available technologies.
Technology & Fit Assessment
We evaluate climate conditions, vehicle types, and operational needs to determine which idle reduction technologies make sense for your fleet.
Regulatory & Compliance Review
We map current and upcoming idle limitation requirements so your fleet stays ahead of fines and penalties, wherever it operates.
ROI & Fuel Savings Modeling
We project fuel savings and payback timelines before you commit to hardware, so the business case is clear up front.
Installed across your fleet, matched to each vehicle’s role
Velociti professionally installs the hardware that fits — from diesel and battery-powered APUs to solar and electrification systems — so cabs stay powered without the engine running.
APU Installation & Integration
Professional installation of diesel, hybrid, or battery-powered APUs providing heating, cooling, and 110v power while cutting idle time.
Solar & Electrification Systems
Roof-mounted solar PV and electrification technology power auxiliary loads and climate control without idling the main engine.
Smart Controls & Driver Coaching
Automatic shutdown/startup systems paired with training that helps drivers understand and change idling habits.

Velociti provides comprehensive auxiliary power and idle reduction solutions built around your fleet — from full APU installation to the specific comfort systems that keep drivers running without the engine.
APU Installation & Integration
Diesel, hybrid, or battery-powered APUs providing heating, cooling, and 110v power while minimizing idle time and fuel usage.
Battery-Powered HVAC
Heating and cooling systems built on a phase-change medium, charged during normal operation of the truck’s A/C — no idling required.
Fuel-Operated Heaters
Efficient diesel-fueled cab heaters that provide warmth on cold nights without ever needing the engine to run.
VeloCare Managed Services
Proactive, unlimited support for your APU and idle reduction systems — unlimited repairs, real-time monitoring, and scalable solutions that keep your fleet running efficiently as you grow. No limits. No boundaries. Just results.
What idling really costs your fleet
Beyond fuel, long-duration idling wears out equipment, invites fines, and hurts air quality — costs that idle reduction technology is built to eliminate.
Rapid ROI
Many anti-idling solutions pay for themselves fast. The City of Columbus found units costing $3,000 each generated projected savings of more than $3,500 per cruiser in the first year alone — with potential savings of $14,000 across a vehicle’s five-year lifespan.
Significant Fuel Savings
Long-haul trucks can burn 2,400 gallons a year idling for auxiliary equipment. At $4/gallon, that’s $9,600 per truck, per year in avoidable cost.
Maintenance Cost Reduction
Excessive idling wears down engines, alternators, belts, and emissions components like DPFs. Idle reduction extends the life of all of them.
Regulatory Compliance
Idle reduction technology helps fleets meet increasingly strict idle limitation requirements wherever they operate, avoiding fines and penalties.
Environmental Benefits
Zero-emission auxiliary power units cut CO2 emissions, supporting anti-idling and sustainability goals — especially valuable for public service fleets.
Emergency Service Enhancements
For emergency vehicles, APUs reduce noise at the scene while still powering warning lights, scene lights, A/C, and communications electronics.
Questions fleets ask us most
Straight answers to what fleet operators want to know before investing in auxiliary power and idle reduction.
Options include engine controls for automatic shutdown/startup, fuel-operated heaters, auxiliary power units (APUs), battery-powered heating and cooling systems, and shore power or truck stop electrification. The best fit depends on your operational needs, climate conditions, and vehicle types.
It varies by technology, but many systems show payback in under 2 years at current fuel prices. Diesel-fueled cab heaters, for example, have shown a 2.4% improvement in fuel economy with a payback of less than 2 years.
APUs move power demands off the main engine and onto a separate power source. Diesel APUs use a small engine to run a generator that provides air conditioning, heating, hotel power, and battery charging; electric APUs use battery systems to power those same functions.
It depends on the type. Diesel APUs need service similar to a regular engine, just at longer intervals. Electric APUs focus more on battery system maintenance, connection points, and eventual battery replacement.
Yes. Solar panels capture sunlight and convert it to electricity that powers auxiliary loads or charges battery systems. Once those batteries are fully charged, excess power can even support accessory loads like radios, lights, and fuel pumps.
Modern APUs are built for diverse climates. Battery systems tend to be more maintenance-free, while diesel APUs provide more robust A/C output and auxiliary power — we’ll recommend the right fit for your specific operating environment.
Yes — Velociti specializes in integrating idle reduction solutions with existing fleet management systems. Tracking software monitors engine performance and helps reinforce driver behaviors that reduce idling, working alongside the physical APU hardware.
