R-8545-16-24P Red Dot Off-Road Backwall Air Conditioner with Heat – 24V, R-134a

The Red Dot R-8545-16-24P Off-Road Backwall Air Conditioner with Heat is engineered for construction, mining, and agricultural equipment operating on 24V electrical systems. Known for producing the highest output of any off-road unit in its size class, the R-8545 series is ideal for compact equipment cabs where performance and reliability matter most.

This model is designed to filter recirculated in-cab air as well as incoming outside air when cab pressurization is required, helping protect operators from dust and debris. It features totally sealed 24V DC permanent-magnet motors with long-life brushes and sealed ball bearings to withstand vibration and harsh environments.

With high cooling and heating capacity, intuitive controls, and a rugged backwall configuration, the R-8545-16-24P delivers dependable, all-season comfort. A 12V heater/A/C version is also available (see R-8545-16P), along with A/C-only variants for both 12V and 24V systems.
