Noise-optimization

Quieter than the engineers who developed it

Where there are people, noise emissions should always be kept to a minimum. This applies in commercial and industrial zones, and even more so in the vicinity of offices, hospitals and residential areas.

The CyberCool 2 is equipped with components that lower noise emissions to a most impressive minimum. So the CyberCool 2 works demonstrably quieter than the STULZ engineering teams that developed it!

Efficient. And reliable. And quiet!

  • For both large ...

    With the CyberCool 2, the optimum operating point can be achieved for every project. Depending on your priorities, efficiency, noise emissions or both can be optimized to suit your individual requirements. The examples below demonstrate the versatility of the CyberCool 2.
