25.3020.05.0000 – Eberspächer Airtronic XL3 D8L 24V Diesel Air Heater (Commercial)

Description

When large cabins or compartments require dependable heat, output matters. The Eberspächer Airtronic XL3 D8L is engineered to deliver powerful, consistent air heating for demanding commercial applications without relying on engine operation.

This 24-volt diesel air heater produces up to 7.6 kW (approximately 26,000 BTU) of clean, dry heat. Because it heats air directly, warmth is available quickly, even in extreme cold conditions. In addition, its stepless heat control maintains stable temperatures rather than cycling on and off.

The Airtronic XL3 is designed for installations where high air throughput is critical. As a result, it is well suited for large truck cabs, buses, personnel carriers, and cargo or equipment compartments that require reliable engine-off heat.

This part number (25.3020.05.0000) is supplied as a heater-only assembly with metering pump. Installation components, controllers, ducting, and accessories are selected separately to allow maximum configuration flexibility.
