Webasto At Busworld 2015: New Roof-mounted Air-conditioning Systems For Mini And Midi Buses

Webasto At Busworld 2015: New Roof-mounted Air-conditioning Systems For Mini And Midi Buses

From October 16 to 21, 2015, Webasto will be presenting its new Cool Top RTC rooftop air-conditioner for mini and midi buses in Hall 5, Stand 507 at Busworld 2015 in Kortrijk, Belgium. For the first time, Webasto will thus be providing air-conditioning solutions that have a cooling capacity of more than 30 kW and is therefore ideally situated for larger midi buses. Further highlights include the new Thermo Top models and the electric High-Voltage Heater (HVH).


Perfect air-conditioning for buses 

The Webasto air-conditioning solutions guarantee pleasant temperatures in the interior – even when the bus is travelling in very hot areas. Until now, the most powerful rooftop system in the portfolio is the Santana L/XL, with a cooling capacity of 18 kW, designed for mini and midi buses with up to 35 seats. With the modular Cool Top RTC 250, 300 and 360 models, Webasto has now significantly expanded its comprehensive range for buses. The new models have a cooling capacity of up to 36 kW and also provide a heating option of up to 35 kW. The high efficiency of the equipment is achieved using the latest component technologies as well as innovative concepts such as the individually switchable condenser fans. Special additional blowers ensure a sufficient supply of fresh air during the journey. Various diagnostic functions, direct access to the refrigerant connections and filters, and individually openable fans for cleaning the condensers make the Cool Top models the most service-friendly systems in their class.

The models of the Cool Top RTC range are compatible with the 24 V on-board power supply and can be easily and inexpensively mounted on the vehicle roof. The rooftop systems will be available worldwide for retrofitting starting in 2016.

Water heaters – high heating power even at extreme temperatures 

Webasto has developed the powerful Thermo Pro 90, with a heat output of 9.1 kW, for minibuses. The high efficiency enables effective heating even at very low temperatures. This is made possible by the Arctic Start function as well as by the gradual heating output control, which enable new application areas even under extreme conditions. The low fuel and energy consumption and the especially quiet operation make a valuable contribution to both cost savings as well as environmental protection. Another highlight in Kortrijk: Webasto will be premiering the Thermo Top Pro 120/150 prototype, its new generation of heaters for the output classes of 12 and 15 kW. The market launch is planned for 2017. These heaters are ideal for use in mini / midi buses.

High-voltage heaters for plug-in hybrids and electric vehicles 

Webasto will also present its electric high-voltage heater (HVH) for hybrid and electric vehicles at the fair. Webasto originally developed the technology for cars, and has now successfully adapted it for buses and other commercial vehicles. The system converts electrical energy into heat with virtually no loss and is very light, with a weight of 2 kg. The heating power is infinitely adjustable from 0.2 to 7 kW.

Effective air heaters for large commercial vehicles 

The Air Top heating systems are ideal for mini and midi buses that require powerful and easy-to-install air heaters. With the models Air Top Evo 40 and Air Top Evo 55, Webasto has once again set new standards in this series of devices. Using an automatic cold start system, the models heat up more quickly and provide a significantly higher heat output. The advantage: despite the higher speed, an efficient and intelligent control system lets the devices consume little power and work very quietly. This is ensured by the built-in exhaust gas temperature sensor, which – acting as a flame detector – accurately measures the heating power and provides infinitely variable control of the fuel pump. If necessary, two heaters can be combined modularly. This function, named Air Top Evo System, provides a heating capacity of up to 11 KW. As a result, even larger buses can be quickly and efficiently heated. 

The air heaters can be retrofitted in the bus interior or under the floor, in both gasoline and diesel vehicles.
