ECHO XL3-D6L Cargo Assembly, 12V

ECHO Cargo Heater Assembly — The Advanced Heating Solution for Temperature-Sensitive Cargo

The ECHO Cargo Heater Assembly delivers powerful, engine-independent heat to keep cargo at stable temperatures in every season. Built around the next-generation XL3-D6L Airtronic heater, it provides fast, even airflow throughout the cargo bay — while the upgraded brushless blower motor and 100,000-cycle ignitor ensure reliable, low-maintenance performance for Class 4–7 trucks.

Protect sensitive goods from frost damage, eliminate dependence on engine heat, and reduce wear on your vehicle’s coolant system — all in a preassembled, plug-and-play system that cuts field installation time significantly.
