Indirect Free Cooling with STULZ Explorer range

Low Noise

The compressors, fans and pumps are the only noise sources with the Explorer units. Depending on operating conditions, the noise level of the chiller can be reduced by up to 10 dB.

To do this, the maximum fan speed is restricted during operation. Furthermore, cooling capacity that is comparable with the standard version can be attained with the low-noise version due to the matching of condensers and fans.

Figure below: Restriction of fan speed - To reduce noise emission, the fan speed is reduced by approx. 30% by the use of a star-delta circuit.

Performance test for more transparency

At our modern test center, each of our STULZ Explorer units is tested before leaving our plant grounds.

If you wish you also can request and witness a performance test under your individual operating and site conditions. This creates transparency and confirms the unit's performance and energy consumption.
