Perfect ice conditions for Olympic performance
As the Olympic Winter Games Milano–Cortina 2026 were approaching, the Cortina d’Ampezzo bobsleigh and skeleton track required a refrigeration solution that would ensure flawless ice conditions. Danfoss contributed with an innovative ammonia-based system, featuring state-of-the-art air purger technology that guarantees consistent ice quality, exceptional energy efficiency, and enhanced safety. Partnering with Energytech and Longofrigo, Danfoss crafted a solution that meets the stringent demands of Olympic competition.
We chose Danfoss for its strong reputation and proven reliability. For a project of this scale, system efficiency and reliability are critical. The integrated Danfoss solution supported our design objectives and ensured optimal operation of the ammonia plant. What set Danfoss apart was its ability to combine automated purging technology, advanced control components, and deep expertise in natural refrigerant (NH₃) applications into one integrated package. This ensured regulatory compliance, long-term reliability, and optimized system performance.
The challenge: Ensuring flawless ice conditions for Olympic performance
The intricate design of the Olympic bobsleigh track demanded a refrigeration system capable of sustaining precise ice temperatures throughout its length. Essential requirements included:
- Consistent ice quality for fair competition
- Prevention of efficiency losses from non-condensable gases
- Reduction of downtime and manual maintenance
- Enhanced safety by minimizing ammonia-related risks
- Seamless integration with advanced control systems
The solution: A fully integrated ammonia refrigeration package
Danfoss provided a pre-engineered ammonia refrigeration package tailored for large-scale applications. This solution featured:
- Enhanced energy efficiency and stable cooling capacity
- Improved safety with reduced ammonia presence
- Automated operations requiring minimal manual intervention
- Smooth integration with control systems for precise management
A central element of the installation is the IPS 8 purging system, which automatically removes non-condensable gases from the refrigeration circuit. In addition, a comprehensive portfolio of valves, sensors, safety components, and variable-speed controls ensures precise regulation and dependable operation under demanding conditions.
The outcome: Reliable performance for world-class events
The refrigeration system delivered the stability and efficiency needed for world-class events. Key benefits include:
- Uniform ice quality across the track
- Optimized system performance through continuous purging
- Enhanced operational safety and improved working conditions
- Reduced maintenance needs thanks to automation
The collaboration between Longofrigo, Energytech, and Danfoss demonstrates how integrated technology, application expertise, and strong engineering partnerships can deliver safe, efficient, and high-performance refrigeration — even on the global stage.
The Danfoss IPS 8 system was easy to install and provides a flexible solution that can be reused for future installations.
