ZERO BREEZE Portable Air Conditioners on the Racetrack

At ZERO BREEZE, we're thrilled to announce our official partnership with Patrick Emerling, a standout driver in the NASCAR Xfinity Series. While this collaboration might come as a surprise to some, it’s actually a natural next step for us. For years, ZERO BREEZE portable air conditioners have been quietly making an impact at racetracks worldwide—whether it’s the high-speed thrill of NASCAR or the cutting-edge pits of student solar and electric racing teams. In every one of these high-heat environments, there’s one feature that sets us apart: portability.

Keeping Cool Between the Flags

One customer once shared a moment he caught during a live race broadcast: the driver had just rolled into the pit lane, helmet on, suit zipped tight, the sun blazing overhead. A crew member stepped in, placed a compact unit right next to the cockpit, aimed the air outlet duct toward the vent port, and within seconds, cool air was flowing in.

"That's definitely the Mark 2!" said the customer. Even on screen, it was easy to recognize—shaped like a travel bag with a convenient carry handle. Also, the battery-powered setup, combined with the front air outlet duct, made it unmistakable as it delivered targeted cooling to keep the driver cool, sharp, and race-ready when it mattered most.

Beating the Heat in Solar Car Racing

While professional drivers in NASCAR and IndyCar face intense heat, solar car racers contend with an entirely different challenge—especially under Florida’s mid-summer sun. At the Solar Car Challenge, student teams like HelioTech are responsible for every part of their vehicle, from initial sketches and CAD designs to the final build and test drives. And because the cars run entirely on solar panels, there’s no room for traditional cooling systems. Worse, those very panels absorb and trap heat, pushing cockpit temperatures dangerously high.

At the 2024 Solar Car Challenge, HelioTech—an accomplished high school team that earned second place nationally—tried using dry ice to manage the heat. While it provided some short-term relief, it was difficult to control and didn’t offer lasting comfort. Now preparing their next-generation solar car for the 2025 competition, the team is turning to a more advanced solution: the ZERO BREEZE Mark 3. With a real compressor-based cooling system, it offers true, dry, refreshing air. Thanks to its portable design, it's directly integrated into the cockpit, helping keep temperatures in check and the driver clear-headed from the starting line to the final stretch.

Battery Cooling for Electric Race Cars

Portable air conditioning doesn’t just benefit drivers and crew—it also protects what’s under the hood. In electric race cars, battery temperature can make or break a race.

That’s why Revolve NTNU, a top-tier Formula Student team, uses the ZERO BREEZE Mark 2 to cool their battery packs before ignition, bringing them down to the optimal range of 59–68°F. The result? Lower thermal stress, better energy efficiency, and greater stability when it counts.

What truly sets the setup apart is how naturally it fits into their workflow. There's no complex setup or time-consuming installation—just place the unit, power it on, and let it do its job while the team handles final checks. No disruption. No delay.

Why Race Teams Choose ZERO BREEZE

The reason is simple: they don't just need cooling—they need cooling that moves with them. That's the portability ZERO BREEZE delivers.

Racing happens fast. Between pit stops, scorching heat, and tight timelines, every second matters. Bulky, heavy units with no handles or complex setups—all the things that slow them down—are not welcome. Crews want units that move with them and operate as efficiently as their tempo. And the cooler that comes to their mind? The ZERO BREEZE Mark 3.

• Compact Design: Measuring just 22" x 10" x 12", the Mark 3 is as small as a travel bag, making it easy to store in tight spaces or transport alongside the crew's gear.
• Lightweight Build: Weighing only 22 lbs—about the same as a large watermelon—it’s easy to grab and go.
• One-Hand Carry: With its ergonomic handle, the Mark 3 is designed for effortless one-handed carry, even up ladders or across uneven ground. No awkward grips or second person required.
• Battery-Powered Freedom: The detachable, off-grid-capable battery means the Mark 3 doesn’t need a wall plug. It’s ready for action anywhere, and can even run off your own compatible battery system.

The unmatched portability of the Mark 3 is exactly why Emerling's crew trusts it throughout the 2025 season. Whether it's keeping the driver cool and focused before the green flag or offering quick relief after a demanding race, the Mark 3 is always within reach. His team shares with us that the Mark 3 isn't just limited to pit lane use—it follows them everywhere. From the garage during tune-ups, to the signature booth where fans line up, and even to the motorhome for a much-needed cooldown after the race, it goes wherever it's needed—no hassle, no waiting. Just reliable cooling that moves with the rhythm of race day.

Cooling That Goes Wherever You Go

Of course, racing isn't the only place where heat makes an impact. From job sites and truck cabins to summer tournaments and wilderness camps, there are countless scenarios where traditional cooling simply can't reach.

That's why we built the Mark 3 with one goal in mind: ultimate portability. Whether you're welding outdoors, hauling freight, navigating a trail, or relaxing at a lakeside camp, you deserve cooling that's as mobile as you are.

With the Mark 3, we've combined double the cooling capacity with the same grab-and-go convenience our users love. Just pick it up, move it, power it on—no friction, no fuss. Wherever your journey takes you, cool comfort should follow—and with ZERO BREEZE, it does.
