Webasto Air Top EVO 40The new Air Top Evo 40 and 55 heaters from Webasto Thermo & Comfort North America are said to offer greater comfort, safety, and heating capacity for various applications on medium-duty and commercial vehicles.

They incorporate an automatic cold-start system, providing up to 10% more heating power to cabins and cargo spaces than previous models. The new Evo models are quieter and have lower power consumption due to state-of-the-art modern controls and a new fuel pump design. With low power consumption and higher efficiency these new heaters are said to be ideal for continuous heating. Multiple heaters can be combined in a modular fashion to allow for heating larger areas as needed.

Webasto’s Air Top Evo 40 and 55 feature an automatic altitude adjustment, ideal for high elevations and leading to optimal operation up to elevations of 7218 ft above sea level (2200m).

The Air Top Evo 40 has a maximum heat output of 13,650 BTU/h while the Air Top Evo 55 has a maximum heat output of 18,800 BTU/h. Both are available in diesel (12/24 volt) or gasoline (12 volt) models.

Quick and easy installation makes the Air Top Evo an economical first-fit and retrofit solution, says Webasto. Common components will also lead to shorter installation and service times.
