Koolbox IV

Space-age technology comes to the racetrack with Koolbox IV and its optional Carbon Monoxide Filter–removing up to 75% of carbon monoxide.

Heat and carbon monoxide are a racecar driver's worst enemies. That’s why we developed a helmet cooling system and carbon monoxide filter to minimize their effects. Our Koolbox IV incorporates the newest carbon monoxide filtering technology.

Air is brought in from a 3" NACA duct and through an external inline blower to the cooler. The air passes through the internal filter and then through the solid-state thermoelectric cooling core. The cooled, filtered air is fed to the helmet through an insulated hose by an internal, high-performance blower. The waste heat from the heat exchanger is exhausted through the top of the cooling unit. The volume of cooled, filtered air to the helmet is controlled by the driver and is variable from 8 to 28 CFM.

Koolbox IV Features & Benefits:

Koolbox IV utilizes state-of-the-art electronics and thermoelectric technology to provide cooling without loss of horsepower.

Koolbox IV uses no Freon. This technology, developed for NASA and the military, eliminates unreliable Freon-based systems.

Koolbox IV uses compact, solid-state cooling technology that will provide consistent cooling for the entire race.

Koolbox IV built-in filter system removes dust and debris.

Koolbox IV helps reduce fatigue by providing cool air to the driver’s helmet.
