PowerCO 2OL CO 2 Rack System PowerCO 2 OL is the name of our most powerful refrigeration rack. Its platform is suitable for a variety of large applications and can be designed as a single or dual-temperature solution. It integrates the CO 2 OLtec EVO modulating vapor ejector technology as a standard feature to achieve high energy efficiency – up to 30% energy savings on an annual basis vs. a standard transcritical CO 2 (R744) system. Multiple configurations are offered, including direct expansion, flooded liquid chillers, pump-assisted flooded low-temperature systems and liquid-toliquid heat pumps. The platform can be packaged in either indoor or outdoor configurations, with a cooling capacity up to 1.5MW (426.5TR) with full heat recovery. All functions are managed by a userfriendly and flexible controller.

Five natural refrigerant systems, described by the nominating companies on the following pages, are finalists for a 2021 Innovation of the Year award. The awards will recognize products, introduced since January 2020, having, or expected to have, a significant impact on the market. Awards will be given in Gold, Silver and Bronze categories.

PowerCO 2 OL was launched in 2020 and has already been installed at iconic sites. To name one example, PowerCO 2 OL has been installed at SNØ – Norway's first year-round indoor ski arena – in Lørenskog. Norwegians and others who love winter sports now have the ability to enjoy Nordic and Alpine skiing year-round. How can we achieve these energy efficiency levels?

PowerCO 2 OL works for many high-capacity applications such as: Distributions centers (warehouse, medium- and low- temperature cold storage) Sport venues (ice rink, ski arena) Processes (food processing, butchery, plastic industry) Heat pumps (domestic hot water, heating and hot water production)

PowerCO 2 OL embeds the CO 2 OLtec Evo modulating vapor ejector technology, assisted by a CO 2 pump. This patented technology has raised the bar in high-efficiency performance with up to 30% annual energy consumption (AEC) reduction compared to a "standard" transcritical CO 2 solution. It has enabled CO 2 systems to become a viable alternative in warmer climates as well as providing heat reclaim advantages in cold and mild climates. In addition, the solution becomes a sustainable alternative by using CO 2 , a natural refrigerant, which is safe and non-ozone-depleting, with a GWP of one.
