Air heater sd air top evo 55 D, 12V – code: 9036996A – Webasto

Webasto SD Air Top Evo 55 D 12V air heater (code 9036996A)

The SD Air Top Evo 55 D 12V air heater by Webasto is a solution designed for those who want reliable air heating onboard, with a technical setup focused on comfort and efficient operation management. The compact size and the “system” setup typical of Webasto air heaters make it suitable for marine installations, where hot air distribution and control quality are central aspects.

In a short time, Webasto air heaters help create a more pleasant and welcoming environment. The ability to manage multiple hot air outlets also supports good dehumidification of the boat, a useful feature especially during more humid periods or stops.

This model is suitable for sailboats and motorboats up to 45 feet, according to the usage indications provided for the range.

Main features and details

Power supply and configuration

• Power Supply: 12V
• Type: air heater
• Supplier product code: 9036996A

Intelligent Blower Control

One of the distinctive elements is the intelligent blower control. Thanks to the control of multiple parameters (via multiple sensors), the heating regulation can disconnect, to some extent, the heat output from the blower speed. In practice, this approach allows optimizing operation under normal conditions, aiming to reduce electrical consumption and contain noise, while maintaining a more “fine” management of thermal output.

Flame detection and start-up management

• New flame detection via exhaust gas temperature sensor.
• Automatic cold start function to promote faster heating in the initial phases.

Components oriented to comfort and installation

• Improved air intake silencer, designed to contribute to quieter operation.
• Vibration dampers for supply pipes, useful to limit the transmission of vibrations to the system.
• Silent fuel pump (DP42) listed among the elements that support quieter operation.

Control interface

The heater is indicated as compatible with the new MultiControl digital user interface. This aspect is relevant for those who want to integrate heating with a more modern and centralized command management, in line with onboard needs.

Typical applications in the nautical field

The Webasto SD Air Top Evo 55 D is particularly suitable when air heating with ducted distribution is desired, typical of installations on:

• Sailboats, where humidity management and cabin comfort are often priorities.
• Motorboats, to improve livability during navigation and at anchor.
• Large yachts, , where the demand for comfort can be higher and the distribution of warm air across multiple zones becomes a practical requirement.

The presence of multiple hot air outlets (depending on the system configuration) helps achieve a more uniform diffusion and supports the dehumidification of indoor environments.

Operational advantages

Rapid heating and efficient management

Among the advantages reported for this model is the power of 5.5 kW, designed for rapid heating. The adoption of the’Intelligent Blower Control is aimed at more efficient operation management, with attention to electrical consumption and noise levels under the most common usage conditions.

Acoustic comfort and perceived quality

The operation is described as very quiet, thanks to the combination of a lower blower speed (at the same thermal power, when possible) and the quiet fuel pump (DP42). Also, the improved air intake silencer contributes to the comfort-oriented setup.

Compact solution for onboard installations

The product is presented as extremely powerful, compact, and quiet, with the goal of ensuring a comfortable climate even on large yachts and in demanding conditions. In the nautical field, compactness is often an important requirement to facilitate the integration of the heater into technical compartments and spaces dedicated to systems.

Usage and notes for selection

System design and air distribution

To achieve the best results from an air heater, it is important that the system is designed consistently with the onboard spaces: ducting, positioning of vents, and flow management directly affect heat distribution and comfort perception. The possibility to provide multiple hot air outlets is a useful element to serve multiple environments and contribute to dehumidification.

Control and command integration

If you are considering upgrading or integrating the command system, consider the compatibility indicated with MultiControl. When choosing, it is advisable to check the overall system configuration and the desired control logic (simple or more advanced management), based on onboard usage needs.

Note on installation and maintenance

In a nautical context, installing an air heater requires attention to positioning, intake, exhaust, and power supply, as well as the correct laying of ducts. For consistent performance and smooth operation, it is advisable to rely on qualified personnel and follow the manufacturer's instructions for installation and maintenance.
