Busworld Europe 2025 is the world’s largest B2B exhibition targeting the bus and coach industry. This year’s event focuses on sustainable transport and the decarbonization of public transportation. Danfoss will showcase its innovative solutions for electric bus thermal management, including BOCK® compressors designed for use with natural refrigerants.
The public transportation sector finds itself at the convergence of several megatrends. We have the drive towards zero emissions, with new models of electric buses being introduced each year. And you have municipalities’ efforts to expand the usage of public transportation in urban areas, which increases passenger numbers and focuses on passenger comfort.
Therefore, the industry needs sustainable solutions for comfortable passenger environments, and Danfoss provides them.
The Danfoss booth will feature the BOCK® HG and HR series of transcritical CO2 compressors, specifically designed to work with the R744 natural refrigerant, including the BOCK® HRX40 CO2 T and the HG24 CO2 T. HG compressors have a compact, lightweight design, which makes them ideal for transport air conditioning systems. They also set benchmarks for low noise and vibration, have a minimal oil carry over rate and a large heating and cooling capacity range.
With the industry's transition to low-GWP refrigerants, CO2 has emerged as an energy-efficient natural refrigerant ideally suited for air conditioning and heating in mobile applications. “BOCK® has over 25 years of experience in working with CO2 compressor technology, and we look forward to presenting our wide range of compressors to Busworld attendees.
Busworld will also provide a launchpad for Danfoss’ newest compressor, the HGZ44, a two-in-one solution that works across a wide range of natural refrigerants. Specifically developed for truck refrigeration applications, the HGZ44 features aluminum housing, for a lightweight design, and supports A2L and HC refrigerants. The compressor is validated for transport and is expected to achieve UL certification by mid-2026.
In addition to providing energy-efficient compressors for mobile heating and cooling systems, Danfoss also offers line components, such as thermostatic and electric expansion valves, solenoid valves, hermetic filter driers and brazed plate heat exchangers that meet the needs of the bus industry. Busworld participants can see the full range of components available at the Danfoss booth, as well as learn how the company can support OEMs on their electrification journey.
One of our goals is to be our customers preferred decarbonization partner, and that includes the OEMs we work with in the bus transportation sector. Due to the breadth of our business, which includes our Editron and Silicon Power divisions, we’re able to offer a one-stop shop for our customers’ electrification needs, including everything from small power modules to complete powertrain systems. We look forward to engaging with them at Busworld Europe 2025, to demonstrate how we can help them achieve their zero-emission goals.

Thermostatic expansion valves (TXV) are available as parts programs, i.e. with separate valve body and orifice assemblies, or as complete valves (fixed orifice). The category also contains thermostatic injection valves.
TGE is an innovatively designed series of thermostatic expansion valves for fluorinated refrigerants. TGE has copper connections upgraded to high-pressure applications for hermetically tight soldering, and is available with a wide variety of connection types and sizes.
The new ETS 8M series offers additional options in the lower capacity end of the Danfoss EEV portfolio. With 4 sizes available from 12 to 40 HP (62 to 114 kW) with high bi-flow MOPD, application costs can be massively reduced by only using one valve in both flow directions.
Danfoss offers a complete range of direct and servo-operated solenoid valves for air conditioning and refrigeration systems. The easy-to-service EVR® valves can be used in liquid, suction and hot gas lines. The valves are compatible with fluorinated refrigerants, including high-pressure refrigerants such as R410A (EVRH).
