Carrier Transicold supports transcritical CO2 research
11th August 2026
GERMANY: Carrier Transicold is donating two NaturaLine container refrigeration units to Technische Universität Berlin (TU Berlin) to support the university’s research into transcritical CO2 refrigeration technology.
The Institute of Energy Engineering at TU Berlin will use the NaturaLine units as a hands-on learning tool for graduate students. Fitted with basic instrumentation, the units will allow students to measure temperature profiles, system pressures and power consumption, helping them learn directly on a real commercial system and gain first-hand insight into how transcritical CO2 differs from conventional refrigeration cycles.
The NaturaLine was the first CO2 marine container refrigeration system when its is was introduced in 2010. Sixteen years on, improving the performance and efficiency of transcritical CO2 systems under a wide range of operating conditions remains a key focus of refrigeration research.
The units will also form part of the institute’s research infrastructure. Researchers plan to integrate and evaluate prototype components inside the units to develop and test future heating and cooling systems, with performance assessed through automated test sequences. Researchers also plan to conduct long-term performance evaluations across a range of operating conditions to better understand commercial-scale transcritical CO2 system behaviour.
