iCOOL OCU Series for LT applications
The possibility to address a larger audience, covering the Condensing Units (CDUs) market that CO₂ is not yet covering today.
- Complete capacity range of compact CDUs for multi-evaporator applications
- Significant energy savings vs. ON/OFF
- Low noise units with special silent features: Inverter compressor, EC fan and 6-face soundproof insulation of the compressor compartment
- Customisation options – fully tested and factory mounted
