Revving up energy savings: How Bosch enabled a leading automotive manufacturer to embrace sustainability with a hybrid ASU system

A leading automotive manufacturer company elevates energy efficiency by digitally transforming ASU units

Industry: Energy and Utilities / Automotive

Challenge:

The client struggled with high CO₂ emissions from gas-fueled hot water generation. Higher energy consumption resulted in higher operational expenditures (OpEx), and the lack of temperature and humidity control in the Air Separation Unit (ASU) led to discomfort during summer.

Solutions used:

  • Implementation of water-source and air-source heat pumps for energy optimization
  • Energy-efficient EC/EC+ fans in ASU units
  • Hybrid heating/cooling mode to optimize both CapEx and OpEx

Immersive Journey

The global crackdown on petrol and diesel car sales, regulatory pressures on sustainable manufacturing and operations, and a volatile energy market are mounting pressures on the automotive industry. Amid rising demand for more innovative energy technologies, decarbonization, and net-zero emissions, automotive leaders also grapple with macroeconomic hurdles such as supply chain disruptions, resource depletion, and geopolitical tensions. Meeting the energy needs while achieving environmental goals translates to a cultural shift for enterprises. Leaders must embed sustainability-driven objectives from strategy to production and the aftermarket phase.

Our client, a leading automotive manufacturer, faced energy and cost optimization issues. Their paint factory generated high CO₂ emissions due to gas-based hot water generation during winters. At the same time, the lack of temperature and humidity control in the ASU led to discomfort during summer. Moreover, inefficient belt-driven fans in ASU blowers resulted in higher energy consumption, leading to elevated operating expenses. They looked forward to establishing an optimal system design to maximize energy efficiency and prevent cost overruns.
