Functional expansion with other systems
The Airtronic D2L functional expansions allow the air heater to work with programmable timers, remote controller operation, and directly with the vehicle’s diagnostic systems. These expansions also enhance the user experience, allowing for better climate control and energy management.


Flexible Installation with 90° Tilt to Either Side
The design of the Airtronic D2L unit allows for flexible installation options to fit a variety of spatial configurations and user preferences. With the ability to tilt the unit 90 degrees to either side, it can be positioned to direct heat exactly where it’s needed most. The heater can be mounted directly in the cab, on the floor or in the rear cargo panel of the vehicle without extensive modifications.
The Airtronic D2L automatically adjusts to altitude, ensuring efficient performance and heat output at heights up to 5500 meters, ideal for mountainous regions.
The Airtronic D2L offers a quiet, stepless blower for smooth airflow and even temperature distribution.
The Airtronic D2L offers backward compatibility, enabling easy upgrades without major modifications and related costs.

Extended Operational Lifespan
The Airtronic D2L has an impressive operational lifespan of up to 5,000 hours, thanks to its advanced brushless motor technology. This technology ensures reduced wear on the motor during frequent usage which also reduces maintenance frequency and replacement. It’s the perfect air heater for users who require consistent uptime and performance.
