ROXSTA systems are designed for economical and energy-optimised operation. Technologies such as parallel compression, ejectors and advanced control strategies minimise energy consumption across all operating conditions.
Lower energy consumption – while maintaining high performance.
Stable operating conditions are essential for reliable system performance. Solutions such as the TECO₂nditioner for compressor stabilisation, combined with intelligent control strategies, ensure safe and continuous operation.
High availability – even under demanding conditions.
CO₂ (R744) is a natural, non-flammable refrigerant with a GWP of 1 and already meets future regulatory requirements.
Investment security through sustainable technology.
The combination of ROXSTA systems and Wurm control technology creates a fully integrated solution. With tools such as FRIGODATA, operators have continuous access to operating data, analysis and optimisation potential.
Transparency, control and optimisation – in one system.
Every application has its own requirements. ROXSTA rack systems are modular in design and can be precisely adapted to specific use cases – from small commercial applications to industrial systems.
Tailored solutions instead of standard concepts.
The waste heat generated by the refrigeration system can be used efficiently – for example for heating processes or hot water.
Maximising the use of available energy.
Thanks to a compact design, well-planned piping and installation-friendly concepts, ROXSTA systems can be installed efficiently and integrated into existing infrastructures.
Reduced installation effort and fast commissioning.
With digital solutions such as FRIGODATA Online and additional tools, systems can be monitored and analysed at any time.
Proactive maintenance instead of reactive troubleshooting.
EVALIFT is a TEKO solution for the energy‑efficient increase of the evaporation level in CO₂ refrigeration systems. By using semi‑flooded evaporators and relocating the superheating from the evaporator, EVALIFT enables higher evaporation temperatures, increases efficiency, and enhances operational safety – for medium‑ and low‑temperature applications.
The TECO₂nditioner optimally conditions the suction gas of CO₂ booster systems at the inlet of the medium‑temperature compressor. This reduces temperature fluctuations, increases system stability, and supports the service life of the compressors – without any additional control effort.
Together towards the best solution
CO₂ refrigeration systems of the ROXSTA series combine efficiency, sustainability and digital intelligence into a future-proof overall solution.
