The Webasto DBW 2016 / Spheros DBW 160 coolant heater

The Spheros DBW 160 / Webasto DBW 2016 coolant heater is a powerful modern solution for heating large vehicles. Perfectly suitable for busses, trucks, and construction machinery, this 16KW diesel heater is powerful, silent, and efficient. 

User Benefits of the 16KW diesel heater

  • Pre-heating high-power engines improves life expectancy and readiness for operation of the engine.

  • Quickly heat up passenger areas in busses without the engine running

  • Maintain comfortable interior temperature at extreme colds on large vehicles with no/poor thermal insulation (construction machinery, large military vehicles, trucks).

  • The Spheros 16KW diesel heater provides hot water and warm air to the cabin.

  • Maintains optimal engine operating temperatures.

Powerful, efficient, and reliable heating

The Spheros DBW 160 is a cutting-edge diesel-powered forced flow coolant heater. It works by circulating coolant with an electric pump. Forced flow heaters warm the coolant and pump it through the engine block, providing uniform heat distribution. Preheating your engine using the 16KW Spheros DBW has multiple benefits: it ensures fast starts for critical applications, significantly reduces fuel consumption and engine wear, and produces less emissions.

The Spheros DBW 160 / Webasto DBW 2016 is a 16KW version of the more sensitive DBW 2010. In order to cope with the higher power output, DBW 2016 is equipped with a brand new heat exchanger and a more powerful drive motor. 

Upgraded with new sensors and a more powerful ECU, this heater is reliable and long-lasting. It’s efficient fuel consumption makes it more affordable and ecologically friendly in the long-term, while the precision design ensures that it functions smoothly and silently.

Currently installed in over 150,000 busses worldwide, the DBW 160 is a staple of heating for large vehicles. Not only does it preheat the engine, it also provides the interior with warm air, and can supply hot water on demand.
