This universal electric air conditioning and heating system is a fully standalone climate solution designed for vehicles that require cooling or heating without relying on engine operation. Powered directly by a battery or generator, this system continues to operate even when the engine is off—making it ideal for trucks, campers, vans, and off-grid vehicle builds.

With low noise output, high efficiency, and energy-conscious operation, this system delivers reliable comfort while reducing fuel usage and overall operating costs.

Key Advantages

Independent electric compressor operation (engine not required).
Cooling and heating functions operate on separate systems.
Energy-efficient design helps reduce fuel consumption.
Low-noise performance suitable for overnight use.
Flexible installation allows mounting in multiple locations.

Power Requirements

12V system requires generator output above 100A.
24V system requires generator output above 70A.
For engine-off operation, battery capacity must support sustained load.
