Danfoss to showcase natural- and synthetic refrigerant-based solutions at Busworld 2023
Danfoss’ exhibit will focus on new and improved compressors for bus air conditioning units. “Traditional and electric buses around the world rely on our compressors as key components in their air conditioning units. As a result, we’re constantly adapting our compressor line to changing market requirements and new regulations,” says Ulrich Frey, Product Manager Mobile Applications at Danfoss. “At Busworld, we’re excited to show updated versions of existing products, and reveal some of our newest innovations within natural refrigerant solutions.”
Madhur Sehgal, Head Sales- Danfoss Climate Solutions, India Region said, “Bock manufactures semi-hermetic compressors that use natural refrigerants, such as CO2. This is a game changer since it offers higher efficiency and the global transition to natural and low-GWP refrigerants. The Bock portfolio is widely used in bus, rail, and truck air-conditioning, and it will fill the gap for us. Indian customers who are travelling will see the latest technology at the exhibit. “
Spotlighting mobile CO2 compressors
One of the exhibition highlights will be the mobile CO2 compressor, StarCO2mpressor. “We’ve been an early mover in developing efficient, reliable compressors for natural refrigerants,” Frey explains. “In this context, functionality, cost-effectiveness, and climate protection must go together. We’ll demonstrate this to exhibition visitors using our StarCO2mpressor, which is available as a 4- and 6-cylinder version.” The compressor’s innovative “star” engine design offers numerous advantages. It features the lowest overall height and weight in the industry and offers the widest frequency range for several performance requirements. “It’s particularly advantageous for energy-saving and environmentally friendly heat generation with a CO2 heat pump to achieve a significantly higher vehicle range,” says Frey. “The compressor has been installed and proven thousands of times since the start of series production in 2019.”
Booth visitors will also see Danfoss’ newly expanded portfolio of semi-hermetic BOCK CO2 compressors. The new model variants on display at the exhibition will include the transcritical CO2 compressor HGX24 with BOCK flexxCO2NTROL technology for digital capacity control – a perfect match for applications where compactness and weight are not the highest priority. This new compressor type impresses with its high efficiency and excellent running smoothness. Danfoss will also introduce a variant with energy-efficient LSPM motors and a UL-certified version for the North American market.
BOCK HG34 series offers flexible and future-proof solutions
Also on display will be the newly expanded line of BOCK HG34 compressor series, featuring an aluminum design for synthetic refrigerants, blends and – as a something new– hydrocarbons. The well-proven design offers several advantages, including low weight, high efficiency and durability. It’s also easier to repair and more sustainable when compared with full hermetic solutions. The compressors come in different variants and with special accessories, which allow customers to adapt them to meet their specific requirements. “For example, our compressors can be used with A2L refrigerants, such as R1234yf or hydrocarbons, which makes them perfectly suited for future-proof use in electric buses,” explains Frey.
