EBERSPÄCHER TO PRESENT NEW AIR CONDITIONING SYSTEMS AT BUSWORLD EUROPE 2023
From freezing cold to tropically hot, thermal management systems from Eberspächer ensure a comfortable interior climate in all outdoor conditions. From October 7th to 12th, the system provider will be presenting primarily new climate-friendly products for alternative drive types at Busworld Europe in Brussels.
Digital and cloud-based services are expanding the portfolio. Visitors can get an insight into the comprehensive range of innovative solutions for city buses and coaches of various sizes at stand 629 in hall 6.
Sustainability is becoming increasingly relevant in public transport in light of the growing population. Eberspaecher is presenting two new air conditioning systems for hybrid and battery-electric buses at Busworld Europe.

With the AC135 AE, Eberspaecher offers a roof-mounted system with a built-in compressor for medium-sized to large passenger compartments. The all-electric platform includes a varied, cost-effective portfolio with a cooling capacity of up to 40 kW.
An integrated battery cooling module maintains a constant battery temperature, which extends the service life and ensures greater efficiency. The system’s lightweight construction additionally promotes low energy consumption.
The AC138 EVO heats and cools medium-sized to large busses in a particularly energysaving manner with its own patented heat pump technology. The innovation lies in the reversal of the air circuit, rather than the refrigerant circuit. This ensures a less complex setup, weight reduction of up to 15% to 325 kg, and, last but not least, a longer range for e-buses.

The AC138 EVO operates on the climate-friendly refrigerant CO2 (R744). The natural refrigerant is much more environmentally friendly and safer than chemical alternatives. With a GWP (Global Warming Potential) value of 1, it has the lowest greenhouse potential used in bus thermal management.
Tried-and-tested systems with new functions
In addition, Eberspächer will be launching updated versions of well-known products in the fourth quarter of 2023: The Hydronic L3 is the successor to the fuel-operated heater with a standard integrated nozzle preheating system.
Preheating the heater fuel allows reliable starting, stable operation, and reduced emissions. For the first time, the new generation has a CAN- and LIN-capable controller and a brushless electric drive. This enables less wear, a longer service life, and greater efficiency. Four versions — from 16 to 35 kW heat output — address the different customer needs.
A special feature is the automatic altitude adjustment. Depending on the model, the Hydronic L3 is suitable for operation at altitudes of up to 4.000 m. In addition, the device can be operated with HVOs without further modification, as is already the case in Northern EU countries. The fuel is made from hydrogenated vegetable oils and reduces greenhouse gas emissions by 90% compared to fossil diesel.
