  • Innovative control

    STULZ's own control system with touch display enables the STULZ Explorer to be perfectly integrated in existing systems.

  • Sustainability

    Due to the reduced piping lengths and the microchannel coils, the Explorer contains only a small amount of refrigerant and protects the environment.

  • Flexibility

    A targeted selection of options as well as the possible customization allow it to be adapted to customer requirements.

Optimised coil surfaces

Standardised use of microchannel coils reduces the heat exchanger depth and thus the internal pressure losses while also facilitating reduction of the refrigerant filling quantity and greater efficiency.

    "Robust design and efficiency, united!"

Compressor chamber

The low-noise version facilitates lower noise levels thanks to the closed compressor chamber and fan speed reduction.
