NAPA 
Delivering trusted solutions and innovation to Australia’s mining industry
As a leading supplier to Australia’s mining sector, NAPA is committed to partnering with trusted suppliers who bring innovative, safety-focused, and efficient solutions to our customers. We understand the demanding environments our clients operate in, and we prioritise products that enhance reliability and performance while supporting operational safety. That’s why NAPA proudly offers Work Air Tech’s Freezebrain AC Amplifier — a breakthrough upgrade designed to transform your vehicle’s air conditioning system.
Specifically tailored for the 76, 78, and 79 Series Toyota Land Cruisers (2007-Current) equipped with the V8 1VD-FTV engine, the Freezebrain is a plug-and-play replacement device that enhances cooling performance by lowering the evaporator temperature by up to 5 degrees Celsius. While the standard Toyota controller limits your evaporator temperature to 6-7 degrees, this next-generation AC Amplifier lets you dial down to as low as 1 degree, granting unprecedented control over your air conditioning comfort.
Installation is straightforward and fully integrates with all stock controls and functionalities. Simply access the AC Amplifier located behind the passenger speaker, remove the factory controller, and replace it with the Freezebrain — no complex tools or modifications needed beyond a 10mm socket wrench. The packaged solution also includes clear installation and operation instructions for ease of use.
Beyond enhanced cooling, the Freezebrain offers diagnostic LED indicators to detect air conditioning faults and an idle control switch that simulates compressor engagement. This feature helps maintain a slightly elevated idle during periods when the compressor is off, ensuring optimal alternator charging — a critical advantage for mining vehicles that experience frequent idling.
With the Freezebrain AC Amplifier available through NAPA, you can upgrade your Cruiser to deliver superior cooling, improved efficiency, and reliable performance in the toughest conditions. The Power of Partnership — NAPA collaborates with the trusted brands and suppliers to bring you innovative products that keep your site and fleet operating safely and efficiently.
