ROXSTAindustrial meets the demands of the industry, food production and logistics perfectly. The transcritical CO2 booster provides a high level of flexibility in order to satisfy customer needs and completely meet the demands within the kinds of use

Capacities

(t0 MT -5 °C / t0 LT -30 °C / tGC 38 °C)

  • Medium temperature 390…960 kW
    4-10 transcritical CO2 compressors
  • Low temperature 0…590 kW
    0-6 subcritical CO2 compressors

Superheat plates heat exchangers for flash and suction gas

Increase in the flash and suction gas temperatures for a safe and stable unit operation.

Active liquid subcooling

For longer piping paths or bigger height differences within the piping network, the ROXSTA series contains active subcooling of the refrigerant. The differences in temperature within a unit are reduced, the behaviour of the unit also remains stable when distances are longer.

Subcooling plate heat exchanger for gas cooler

For attachment of an exterior chiller. Especially in southern countries, the additional cooling of the refrigeration circuit can keep a transcritical unit energetically stable. In doing so, sensitive products are protected.
