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.
Modular air conditioning system (MACS)
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.
