Welcome to the world of efficient trucking! Today, we're diving deep into the features, benefits, and installation details of the Polar Fox APU system, specifically designed for the 2020 Volvo VNL 860. If you're a trucker looking for an effective way to manage your energy needs while on the road, this blog is for you. Let’s unpack all the essential elements of this innovative system.
Understanding the Polar Fox APU System
The Polar Fox APU is a game changer for truckers, especially those operating heavy-duty vehicles like the Volvo VNL 860. This advanced system is designed to provide power without the need for idling, which not only saves fuel but also minimizes emissions. Let’s break down the core components and what makes this system stand out.
Core Components of the System
At the heart of the Polar Fox APU is a compact and efficient setup. The installation process involves several key components:
Evaporator Unit : This unit is designed for optimal airflow within the vehicle.

Compressor Unit: Located conveniently, this control unit is essential for managing the system's operations.
Polar Fox APU - Compressor Unit Condensing Unit: This is the only component that needs to be mounted outside the vehicle, simplifying the installation process.

The design of the system is such that it occupies minimal space, making it ideal for trucks like the VNL 860, which have limited room on the passenger side. This compactness means that truckers can enjoy the benefits of an APU without sacrificing valuable space.
Installation Insights
Installing the Polar Fox APU is straightforward and can typically be completed in 5-6 hours by a skilled team. This speed is a significant advantage over traditional diesel-powered APUs, which often require more extensive modifications and installation time.
Battery System
One of the standout features of the Polar Fox APU is its dual-purpose lithium battery system. This innovative battery technology replaces traditional lead-acid batteries, offering several benefits:

Bluetooth Enabled: You can easily monitor your battery's charge state and discharge levels through a simple app.
Lightweight: The lithium batteries reduce overall weight, which is crucial for maintaining compliance with weight regulations.
Long Lifespan: Unlike lead-acid batteries, which often need replacing every few years, these lithium batteries come with a 5-year full replacement warranty, significantly reducing long-term costs.
By using existing battery hardware, the installation becomes even simpler, and truckers don't need to worry about upgrading their alternators unless they want the faster charging capabilities of a 200 amp alternator.
Key Benefits of the Polar Fox APU
Now that we've covered the installation and components, let’s delve into the primary benefits of the Polar Fox APU system. These advantages make it a compelling choice for any trucker.
1. Zero Emissions
One of the most significant benefits of the Polar Fox APU is its zero-emission operation. Traditional diesel-powered APUs can emit harmful pollutants, but with the Polar Fox, you can operate without contributing to air pollution. This is particularly important for drivers who are conscious of their environmental impact.
2. Cost Efficiency
When it comes to cost, the Polar Fox APU shines. It is priced at about 60-65% of traditional diesel-powered APUs, and with lower operational costs, truckers can save significantly over time. Additionally, the reduced need for battery replacements means more savings in the long run.
3. Maintenance-Free Operation
Truckers will appreciate the maintenance-free aspect of the Polar Fox APU. Other than cleaning the evaporator filter every so often, there’s minimal upkeep required. This ease of maintenance allows drivers to focus on the road rather than worrying about their APU.
4. Lightweight Design
As mentioned earlier, the system’s lightweight design is a major advantage. This can be crucial for truckers who are close to their weight limits, as the Polar Fox APU can help maintain or even reduce the overall weight of the vehicle.
Customization Options
Every trucker has unique needs, and the Polar Fox APU recognizes this with its customization options. For those who require specific configurations, there are several ways to tailor the system to fit individual needs:
Ducting Options: The system allows for various ducting configurations to ensure the best airflow in the cabin.
External Compressor Housing: If space is tight, there are options to house the compressor unit outside the truck, ensuring that the internal space remains free for other uses.
The Polar Fox APU also offers a dealer installer program. This program not only provides a quick installation process but also offers dealers the opportunity to earn a profit from both the product and the labor. For fleets, there’s a fleet trial program that allows companies to try out the system in one of their trucks for up to 120 days, helping them make an informed decision before committing to a larger purchase.
