Eberspächer Airtronic and Hydronic

Fuel Operated Heaters

Eberspächer Airtronic and Hydronic

Two technologies – one goal: maximum comfort

Cold outdoor temperatures are no problem for the pre-heaters from Eberspächer. They always create the perfect climate in the rear area and driver’s cab of minibuses and midibuses, thus ensuring that the highest level of comfort for the passengers is guaranteed and that the driver has the best possible working conditions. With the – ethanol, petrol or diesel operated – Airtronic air heater and the Hydronic water heater, Eberspächer provides the optimum climate.


Airtronic air heaters

Fast, quiet, with capacity to spare

Eberspächer Airtronic air heaters heat the air in the minibus or midibus and distribute it through individually positioned air outlets. This is why the Airtronic is especially suitable for quickly and efficiently heating the driver’s cab and the rear area for passengers. A constant interior temperature can be maintained for an extended period thanks to the low fuel and electricity consumption.

Power range: 2 to 8 kW

The main benefits:

  • Rapid rear area and driver’s cab heating 
  • High heating performance with compact dimensions
  • Extremely quiet operation for even more comfort
  • Stepless heating performance control
  • Integration into the vehicle control unit via CAN/LIN/S+ interfaces
  • Intuitive operation, e.g. using the Eberspächer EasyStart Pro and EasyStart Web control units
  • Compact size – flexible, uncomplicated installation under the floor, under the driver’s seat or in the rear area
  • Installation position can be angled 90° to both sides
  • Service life 5,000 h
  • Protected against dust and sprayed water
  • Automatic altitude adjustment up to 5,500 meters*

* Depending on variant


Airtronic Ethanol

Ethanol heaters for minibuses and midibuses

The Ethanol variants of the Airtronic family combine all professional properties of the fuel or diesel operated variants with the specific requirements for emission-optimized driving. They are almost CO2neutral during operation. The Airtronic Ethanol versions heat the rear area and driver’s cab of the minibus or midibus very rapidly without compromising the vehicle’s range.

The main benefits:

  • Durable and robust heating performance
  • Rapid rear area and driver’s cab heating
  • Protected against dust and sprayed water
  • Compact size–flexible installation under the floor, the driver seat, or in the rear area
  • Intuitive operation, e.g. using the Eberspächer EasyStart Pro and EasyStart Web control units
  • Integration into the vehicle control unit via CAN/LIN/S+ interfaces

Hydronic S3 water heaters

An efficient heat source for the highest levels of comfort

When integrated into the vehicle’s coolant circuit, the Eberspächer Hydronic S3 can pre-heat the engine at standstill while heating the entire rear area of the vehicle at the same time – ideal for all passengers and the driver. The Hydronic S3 combines maximum comfort with stable heating performance and low fuel consumption. As a result, the minibus or midibus is already at a pleasant temperature when personnel/passengers get in and is ready to go immediately.

Power range up to 5 kW

Additional models with higher heating performance up to 12 kW available

The main benefits:

  • High heating performance
  • Rapid operational readiness and durability
  • Space-saving installation in the engine compartment
