Plug & play HVAC
Liebherr's modular air conditioning system meets the railway industry's toughest demands, offering standardization and adaptable flexibility.
The universal HVAC standard for multiple railway platforms
As a multi-platform standard Liebherr has readily developed a modular HVAC design that is suitable for different rolling stock platforms with different cooling power demands. Each module consists of identical standardized components.

Liebherr has developed MACS, a modular air conditioning system designed to meet the most demanding requirements of the railway industry, such as a high degree of standardisation and adaptability to power needs by a modular architecture.
Key features and benefits
Flexible configuration
- Modules can be arranged to suit individual car designs and cooling power requirements.
- Includes options for cab climate control.
Simplified maintenance
- Individual modules are easily replaceable for off-car repair, streamlining maintenance and spare parts management.
- Customizable service concepts optimize schedules to meet operators' needs.
High availability through modularity
- Multiple cycle redundancy ensures continuous operation, even if one module fails.
- Minimizes unplanned downtime to maintain reliability.
Cost-efficient operation
- Reduces development time and costs by up to 70%.
- Total cost of ownership is approximately 10% lower than comparable HVAC systems.
Future-proof and environmentally friendly
- Supports next-generation cooling technologies, including CO2-cooled modules with identical interfaces.
- Modular small-cycle CO2 design ensures easy maintenance and safe operation.
Technical advantages
- Compact and lightweight design: 220 mm profile height, weighing only 125 kg per module.
- 70% greater cooling power density and 8% lower power consumption compared to typical HVAC systems.
Consistent evolution for long-term performance
MACS 8.0 is continually upgraded to ensure seamless integration into new projects, eliminate obsolescence, and maintain a high maturity level. Liebherr’s life-cycle engineering approach guarantees long-term value and adaptability. With MACS 8.0, Liebherr offers a universal HVAC standard that is lighter, smaller, more energy-efficient, and optimized for multiple railway platforms.
