Category: Tag: Regions:

TEKO’s new series solution is tailored for large supermarkets and hypermarkets. The TEKO ROXSTA G6 covers also many requirements in the field of food production and logistics.

Compact design

The combination of powerful 6-cylinder compressors with frequency controlled 4- or 6-cylinder guide compressors gives the TEKO ROXSTA G6 an extremely compact design for this capacity range. It does not leave out the optimally matched partial load requirements.


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

  • Medium temperature 207 to 640 kW, 3-7 transcritical CO2 compressors
  • Low temperature 0 to 590 kW, 0-6 subcritical CO2 compressors

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.

Efficiency improvement

We are happy to advise you which efficiency-enhancing technologies are right for your project.
