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.
