CTM 6 Combi

Danfoss Multi Ejector SolutionTM makes CO2 refrigeration systems economically competitive with the HFC systems at all ambient temperatures by improving COP in comparison to standard booster and parallel compressor systems. CO2 systems with Multi Ejector SolutionTM can be installed in any climate delivering lower energy consumption than i.e. R404A. It removes the CO2 equator entirely.

CTM 6 Combi consists of High Pressure and Liquid Ejectors built into one Multi Ejector block. This solution is designed for CO2 transcritical systems to lift gas and liquid from MT suction accumulator and mix it with the gas coming from the gas cooler at medium pressure level.

Features and benefits

  • Reliable and robust design, proven through extensive field tests that also contribute to first cost savings during implementation.
  • Fully integrated solution that eliminates the need for additional components such as check valves or motorized ball valves.
  • Completely serviceable design, supported by a wide range of spare parts and accessories.
  • Easily accessible strainer/filter that ensures faster and more efficient maintenance.
  • Improved COP and enhanced operation of parallel compressor systems reduce the required swept volume for MT compressors, resulting in noticeably lower energy consumption and contributing to fast payback.
  • Delivers clear savings for end users through optimized efficiency and reduced operational costs.
  • Higher suction pressure—enabled by Liquid Ejectors working together with Adaptive Liquid Control (ALC)—reduces energy usage and improves evaporator utilization, driving significant operational savings.
  • Increased system efficiency reduces overall energy consumption, naturally supporting a faster payback period.
  • The combination of the Multi Ejector Combi and Danfoss CALM controllers ensures easy setup and commissioning, while providing robust system control for many years of trouble‑free operation.
