The ROXSTA 2.0 from TEKO is suitable for larger supermarkets, food production and logistics or warehouses. For difficult placement situations or narrow machine rooms, the machine and medium pressure station can be separated on site.

Capacities

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

  • Medium temperature 36…320 kW
    3-6 transcritical CO2 compressors
  • Low temperature 0…240 kW
    0-5 subcritical CO2 compressors

Freshness first

The quality of chilled goods always is the highest priority. When using heat recovery/heat pump or climate function the first step is to check whether the goods temperature is safe.

Parallel compression

In larger power ranges (> 80 kW), parallel compression can deliver significant efficiency advantages. In combination with our control concept, it is checked during the operation of the unit whether the ECO compression is an advantage. Depending on this, the feature is activated or not.
