Stulz’s Explorer WSW range of water-cooled chillers has cooling capacities of 230 to 430 kW with one compressor or 460 to 1530 kW with two compressors. They can be easily adjusted to different cooling loads thanks to two refrigerant circuits with semi-hermetic screw compressors and infinitely variable output sliders. Applications include data centres, communication rooms, industrial and commercial buildings and telecommunications.

Standardised components include shell-and-tube condensers that can be set to operate at different temperatures — for example, with well water, cooling towers or external recooling heat exchangers.

Following extensive customer consultation, Stulz identified a clear demand for a compact, corrosion-resistant device that emitted low levels of noise. For noise-critical applications, there is a low-noise version with extra acoustic insulation that meets the sound-power-level requirements of ISO 3744 and reduces them by a further 10 dB.

These chillers achieve high efficiency at part load. Depending on service conditions, they can achieve ESEER (European seasonal energy efficiency ratio) of five or more.

Features include an automatic transfer switch, energy meter for total power consumption, soft start and anti-vibrations mounts.
