Overview

Developing zero-emission public transport requires manufacturers to rethink more than the vehicle powertrain. Components supporting onboard pneumatic functions must also meet demanding requirements for weight, energy use, noise, integration and reliability.

 

Aluminium Revolutionary Chassis Company (ARCC), an Australian developer of zero-emission bus chassis, worked with Gardner Denver Transport to develop compressor solutions for its electric and hydrogen-powered bus prototypes. The collaboration ultimately led to the use of the TX02 compressor, selected for its lightweight design, simple integration and quiet operation.The project supports ARCC's goal of developing Australian-designed and built buses that move public transport away from conventional diesel engines toward electric and hydrogen technologies.

Challenge: Reducing Weight for Zero-Emission Buses

Founded in 2016, ARCC set out to develop a zero-emission bus chassis designed and built in Australia. The company developed two prototypes: one fully electric bus and another using hydrogen fuel. Both vehicle designs were developed from the ground up with a particular focus on reducing overall bus weight and the energy required to power the vehicle. This required an approach to onboard pneumatic equipment that complemented the wider vehicle design. The compressor needed to support pneumatic functions while addressing the requirements of a new zero-emission vehicle platform.ARCC approached Gardner Denver Transport after learning about its earlier work with Wrightbus, where Hydrovane compressors had been installed on 1,000 hybrid-powered London Routemaster buses.

Solution: TX02 Compressor for Electric and Hydrogen Buses

Following discussions and a visit to Gardner Denver's Redditch facility, an initial compressor solution was recommended for ARCC's electric vehicle program. The collaboration later expanded when ARCC began developing its hydrogen-powered bus prototype.For the hydrogen bus, the requirement was for a lighter, more robust compressor, leading Gardner Denver to offer a package based on the TX02. The TX02 provides several characteristics relevant to zero-emission public transport:
  • Lightweight design to support vehicle weight objectives
  • Simple integration with electric drive applications
  • Quiet operation for public transport environments
  • Vibration-free operation supporting passenger and pedestrian comfort
  • Flexibility to accommodate vehicle integration requirements
The project combined engineering expertise from the UK with regional support in Australia, creating a cross-border engineering and service approach for the customer.

Impact and Results

The collaboration enabled ARCC to integrate compressor technology into both electric and hydrogen-powered bus development.The main benefits documented by the case study include:
  • Easy chassis integration: compressor products were designed to integrate with ARCC's vehicle chassis while allowing modifications where necessary.
  • Reduced equipment weight: the TX02 was selected specifically where a lighter compressor was required.
  • Quiet operation: the compressor helps address noise considerations important to urban public transport.
  • Vibration-free performance: the TX02 supports comfort requirements for passengers and pedestrians.
  • Support for zero-emission technology: the compressor package supports onboard pneumatic requirements within ARCC's electric and hydrogen bus development.
  • International engineering support: centralized expertise in the UK was combined with regional support in Australia.
The source also reports that the international team delivered the project on time and within budget.

Customer Quote

"Gardner Denver has been indispensable throughout the last four years and has played a key role in our efforts to provide sustainable public transport in Australia. The company’s products are easily integrated on our chassis but the team has made it clear they are happy to accommodate modifications where necessary."
