Dear customers and partners,
We develop intelligent products around the Webasto advanced core technologies and integrate them into large and innovative comfort solutions for every recreational vehicle: this is the vision we have been aiming at for years and which is still the base of our product roadmaps today. Since the RV market is going more and more towards more compact vehicles and the coming stricter EU regulations will limit further the payload, Webasto solutions are getting even more attractive as they can contribute quite significantly to the reduction of weight and to safe space in the inner cabin. Looking back, we are proud to have been the first supplier to introduce diesel technology into the RV market more than 15 years ago, and to have provided OEMs with the opportunity to build totally gas-free vehicles. Since then, we have continuously improved our products to increase the level of on-board comfort and autonomy. Our gas-free solutions or hybrid solutions (cabin air heating with diesel + water heating on gas) both bring outstanding savings when it comes to weight (less gas on board) and inner space (smaller gas tanks, underfloor mounting
of our products). Our Range Plus kit, including a fuel-powered air heater and a fuel tank (HVO-ready), extends the range of E-Vans under cold conditions and ensures warm interiors, creating new possibilities for electric RV. More recently, we highlighted the benefits of new, ultra-silent and high-performance refrigeration compressor technology for our customers. As a result, for example, happy caravan owners enjoy large innovative drawer fridges and the pleasure of having ice or cold drinks even in extremely hot climate conditions. Besides the well-known Freeline 115 Elegance and Freeline Slim 140, customers can profit from the two fridges Freeline Slim 70 and Freeline Slim 90. Both products are the lowest-power-consumption fridges on the market in this size and being slim and tall offers a great option for small vans where interior layout is challenging. Additionally having the space constraints of compact vehicles in mind, Webasto offers some special shaped products like BI 16 and BI 30 including updated verisons of BI 29 Dual, BI 36 and BI 41 Dual – top loading cooling boxes.
Our continous commitment in the development of new technologies drives us, bringing new ideas and keeping all of our customers satisfied. Air-conditioning is one of the core competences at Webasto. With the BlueCool Drive 40, we bring a powerful air-conditioning product which provides also cold air to the rear passengers while driving. To protect the environment in the best possible way, Webasto attaches great importance to making its products as sustainable as possible. One contribution to this is the conversion of its Cool Top Trail rooftop air-conditioning systems to the refrigerant R32. Therefore, all sizes of the air-conditioning unit are now available with the gas named the ‘G series’. Innovation should translate into beneficial features and great ease of use, not only of our products but also of all peripheral sales and application tools which make your life easier in installing and maintaining our products. Please register on our dealer portals and gain exclusive access to our extensive training programmes (online or on site) with the ultimate goal to be part of our network and
to help you develop new sales potentials. RV is our passion. Just as it is yours. We hope that this catalog assists you with your season and if you do have any suggestions or feedback, please do not hesitate to let us know. We look forward to enjoying a new motorhome and caravan season with you.
Enjoy more comfort. Enjoy more independence. Enjoy more Webasto. Your Webasto RV Team

A logical vision: Rely on the energy source you already have on board
Enjoy comfort, enjoy independence In all seasons and under all weather conditions
Webasto has always prioritized the fuel of the vehicle as the most logical, readily available, main energy source. This strategy is complementary to gas – it has been working properly for decades now. And it makes full sense, especially for big energy consuming functions like cabin heating.
Since the very start of our activities in the recreational-vehicle industry, we have always focused on innovation as a main business development driver. Our vision is to ensure greater comfort and freedom with our products for motorhomes and caravans. For enjoying greater independence, all our heating systems are based on diesel. Diesel is available no matter where you go and is taken directly from the vehicle‘s fuel tank. This ensures unlimited freedom!
Our comfort solutions additionally enhance well- being atmosphere in your motorhome or caravan by providing cooled drinks or food from a fridge or travel box. With Webasto you can enjoy unforgettable moments in your motorhome and caravan. That is what we mean by ”Enjoy comfort, enjoy independence.“ That is Feel the Drive.
Long tradition Since its foundation Webasto has been a family-run company where high-performing quality products are our main purpose.
Innovative technology High investments in R&D and the continuous development of new technologies allow us to keep all our customers satisfied.
More space inside Most Webasto heaters can be mounted outside the vehicle. This significantly increases the total storage space inside the motorhome. Less weight In winter, on average 90% of the gas carried with the RV is needed for heating. With Webasto products you can downsize your gas stock to one single 5 kg bottle and gain up to 35 kg for additional load inside the vehicle. Perfect climate on board Thanks to the stepless power regulation and Gasoline for continous heating. Webasto heaters manage to maintain a stable cabin temperature with a hysteresis lower than 0.40°C. This creates greater passenger comfort.
Increased fuel autonomy Diesel fuel is standardized worldwide and almost everywhere available even in the most remote places Precise monitoring of fuel supplies via fuel-gauge possible No extensive procurement of gas bottles in foreign countries necessary No adapter for foreign gas bottle connectors necessary Heating whilst driving in any country without the need of purchasing additional security valves. Thus, enjoying a warm cabin from the very first minute on

Introduction to autonomous camping Innovative technology for more freedom – heating with diesel
Besides the fact that you can gain more space inside the vehicle or increase your payload when heating with diesel, it provides you with more freedom and autonomy. Exactly what you need when you are on holiday and want to relax rather than wonder where to get new gas. Diesel heating is not that new anymore to the motorhome market as Webasto has been providing sophisticated solutions for years. Heating with the fuel provided by the vehicle fuel tank is the smartest way to make use of the existing fuel on board.
This enables you to reduce the overall gas consumption e.g. in winter by almoust 90 %. You can get diesel fuel anywhere whereas finding proper gas supplies might end up in some annoying hassle also due to the different gas bottles and adaptors used through-out Europe.
By heating with diesel you can benefit from
Webasto – market leader when it comes to diesel heating
Every year, Webasto produces more than 1 million fuel-operated heaters heaters for all kinds of markets: car, truck, light commercial vehicle, off-highway, special vehicle, rail, bus, recreational vehicle and marine. Quality, reliability and performance have always been our top priorities. We test our systems regularly in our own climatic test chambers against the highest quality standards, exposing them to varied and extreme temperatures and weather conditions. This enables us to adapt them perfectly to your motorhome needs.
Carrying less gas bottles leads to an increase of payload
Less hassle to find supplies in foreign countries Reduced physical handling of heavy gas bottles (2 x 11 kg gas bottles can weigh up to 54 kg) Heating whilst driving without any further expenses Thus, enjoying a warm cabin from the very first minute of your stay

Air heaters Application concept
Air heaters Advantages
How Webasto air heaters work When the unit is switched on, the fuel pump feeds fuel from the vehicle‘s fuel tank to the heater. Here the fuel is automatically ignited by means of a glow plug. In the combustion chamber, a flame is lit which heats up the heat exchanger. The unit takes air in from the outside for combustion purposes and the combusted exhaust air is discharged to the outside. During heating, the integrated fan takes in the air to be heated through the inlet and feeds it through the unit. As the air flows through the heat exchanger, it heats up and is then distributed through the outlet. The connected hot air pipes now spread the air evenly throughout the vehicle interior. Due to the unit’s own separation of the combustion circuit from the heating circuit, there is no impairment of the quality of the hot air. A temperature sensor constantly measures the interior temperature and automatically adapts the heating power output by adjusting the amount of air passing through the unit. In this way, the temperature selected by the user is rapidly reached and maintained at a constant level. After the unit has been switched off, the combustion process is terminated in a controlled manner. For this purpose, the unit briefly goes into re-run mode to cool itself down. It is then immediately ready for restarting.
The advantages of Webasto air heaters Optimum heat output at high altitudes thanks to altitude sensor (Evo range) and altitude mode integrated in MultiControl Automatic altitude adjustment (Air Top Pro 25) Heating power from 0.9 kW to 5.5 kW Very compact heaters for easier and faster installation Smooth blower and burner operation for low-noise and fuel consumption Hot air is channeled and distributed through the motorhome, ensuring a constant temperature Precise and stepless cabin temperature control Very fast heat-up phase Low-noise operation Diesel-fueled, directly fed from the tank More space inside due to the possibility of outside installation Heating while driving allowed in all countries

Range Plus system Extends the range of E-Vans under cold conditions and ensures warm interiors
Despite new generation battery technologies and battery management systems, heating the interiors of electric vehicles during periods of cold weather limits the range of the electric car per battery charge by up to 35 percent. Heat escapes as a result of frequent door opening. Window areas cause vehicle interiors to cool down quickly. Transportation of temperature-sensitive goods demands a reliable and constant ambient temperature, for which energy is required to heat the cargo compartment. The Webasto Range Plus system – a fuel-powered air heater plus fuel tank – significantly reduces the load on the vehicle’s existing electric heater. It moreover ensures pleasant temperatures for passengers and everyone who relies on a warm vehicle for work. Retrofit of: Heat source air heater
Further possible applications: Student transport Transport of disabled or sick persons Mobile workplace Transport & storage of temperature sensitive materials
Set includes: Air Top Pro 25/Air Top Evo 40 D 12 V Vehicle-specific installation kit Air in-/outlet, air routing, external temp sensor, heater bracket, wiring harness extension, etc. Fuel tank, tank-level sensor, tank-level indicator (LED), fuel-filler assembly, refuel cap Available for: Mercedes EQV/E-Vito Tourer/ VW ID.Buzz Cargo/ VW ID.Buzz Van/ Ford e-Transit, Stellantis K0 (Peugeot Expert / Citroën Jumpy / Opel Vivaro)

Water heaters Application concept
Water heaters Advantages
The advantages of a Webasto water heater Supply of warmth via the air outlets in the dash board Cabin heating and optional pre-heating of the engine Heating power from 2 kW up to 9 kW Less emissions due to engine pre-heating Very fast heat-up phase Quiet-running, low-noise operation Diesel-operated, directly fed from the vehicle‘s fuel tank or electrically driven via 230 V power socket
How Webasto water heaters work When the unit is switched on, the fuel pump feeds fuel from the vehicle‘s fuel tank to the heater. Here the fuel is automatically ignited by a glow plug. If combustion does not occur immediately, the unit automatically repeats the start-up procedure. A flame is ignited in the combustion chamber which heats up the heat and the coolant exchanger. The unit takes air from the outside for combustion purposes and the combusted exhaust air is discharged to the outside. During heating an internal circulation pump feeds the water-glycol mixture through the unit. As the water-glycol mixture flows through the heat exchanger, it heats up. In the connected water circulation system, heat exchangers then transfer the energy to the interior and the engine. Once the vehicle interior or engine has warmed up, the heat requirement is reduced and the water temperature continues to rise. At a pre-set temperature threshold the unit reduces output at this moment or goes into standby mode. The heating procedure automatically restarts when the water temperature drops below a certain level. The unit thus adapts the heat output automatically to the heat requirement. After the unit has been switched off, the combustion process is terminated in a controlled manner. For this purpose, the unit briefly goes into re-run mode to cool itself down. It is then immediately ready for restarting.
