Modulating Burner

• Webasto heaters have a Variable Heat Output from the maximum heat output down to the minimum output resulting in comfortable economic heat levels in relation to ambient temperatures.

Step-less power modulation

This results in a stable internal temperature and the absence of disturbing sudden noise increase

Temperature control logic is extremely precise.Stepless Control – Other manufacturers heaters use a stepped heat control. Switching

between these levels can lead to being either too warm or too cold, as the desired temperature is never controlled accurately. These sudden step changes also lead to distinct noise level changes, which can easily cause sleep pattern disturbances.

The electrical consumption is also kept at a precise control & not peaking and dropping due to the heater switching on & off as it attains temperature.

Ceramic Glowpin

Webasto have used this ‘state of the art’ technology for a number of years.

As you can see from the diagram below, the ceramic glowpin is significantly smaller in size. The heating element is straight and smooth in design, unlike the bulky winding element of the glowplug, still used by other heater manufacturers today.

The main benefits of using the ceramic glowpin are:

¨ Reduced Battery Power Draw¨ Increased Reliability¨

In the Airtop 3500 and the Airtop 5000 models, the glowpin also incorporates a flame detector, thus reducing component parts and stocking levels.

Other Features & Benefits

Ferrotec Burner Fleece, which has replaced the old cloth matting fleece. This concept uses metal to assist in achieving longer life.

A Self Diagnostic Blink Code is built into the on/off switch, providing quicker fault diagnosis in the event of heater failure, therefore reducing vehicle down time. Our heaters do not lock out or require specialist diagnostic equipment.

Low Noise Output

Integral Control Unit, using less wiring, thus reducing the risk of loose or corroded connections.
