Thermo Pro 90 HDD

Introduction

Dear Webasto Customer,

Thank you for purchasing the Thermo Pro 90 HDD water heater from Webasto. We hope that 

you will find it gives you reliable comfort for years to come.

The heater Thermo Pro 90 HDD works together with the vehicle's heating system to preheat 

the cab and engine in parking heating mode.

Regular use of the heater can provide the following advantages:

– Improved safety thanks to clear all-round vision from the moment you move off.

– Reduced wear and cold-start emissions thanks to engine preheating.

– Achieving the comfort temperature even with engines with low waste heat thanks 

to the Heating during Travel option.

– Comfort temperature is reached automatically and in an energy-saving way in 

vehicles with start/stop system thanks to corresponding heater integration (engine-off 

integration).
