Air Top Pro 25 Air Heater Details

The new Webasto Air Top Pro 25 delivers advanced features for improved efficiency and reliability. Equipped with automatic altitude adjustment, the system ensures consistent heating performance without requiring manual recalibration and adapts seamlessly to varying elevations. 

A new brushless motor enhances efficiency by reducing fuel consumption, minimizing noise, and extending the heater’s service life, making it good for demanding applications. 

With a maximum heat output of 8,500 BTU/h (2.5 kW), the Air Top Pro 25 rapidly warms vehicle interiors to a comfortable temperature while maintaining quiet, steady operation.

Operates on Multiple Fuel Types

Engineered for versatility, the Air Top Pro 25 supports multiple fuel types, including: 

• Diesel

• Gasoline

• Hydrotreated vegetable oil (HVO)

Once the set temperature is reached, it transitions to a low partial load mode, further reducing fuel consumption while maintaining consistent performance.

High-Performance Heating Solution 

The heater’s advanced brushless motor and variable load functionality provide precise temperature control and extended durability. Designed to integrate seamlessly with modern vehicle systems through protocols such as LIN and CI bus, it offers a flexible, high-performance heating solution for commercial vehicles, cargo spaces, and RVs.

Proven Commercial Vehicle HVAC Systems

Webasto will also highlight its range of commercial vehicle HVAC systems at its booth during Work Truck Week 2025.

Designed with a focus on component commonality, these systems improve spare part availability, enable faster customer support, and reduce vehicle downtime—key factors in maximizing customer satisfaction.

Webasto is also equipped to design custom kits to meet specific customer requirements, ensuring tailored solutions for unique applications. 

Every HVAC system is backed with a standard 3-year warranty, further reinforcing the company’s dedication to quality and customer success.

“Implementing local production with standardized components is crucial for ensuring an available inventory of spare parts for our OE customers, dealers, and end-users,” said Mike Cicioni, key account manager at Webasto Thermo & Comfort NA. “It also aligns with our goal of expanding our Made in America product portfolio.”
