Stulz launches WPAmini series

The Stulz WPAmini provides free cooling for data centres and industrial applications with low cooling needs, delivering a cooling capacity of 160kW in a very small footprint.

The Stulz WPAmini series offers free cooling in a small footprint.

The chillers are equipped with two redundant refrigerant circuits to increase operational reliability. The circuits are controlled according to the required cooling capacity, so that the respective circuit is activated with maximum efficiency when minimal cooling is needed.

The WPAmini is equipped with oversized aluminium microchannel condensers and four scroll compressors, which are activated and deactivated (25, 50, 75, 100 percent) in stages.

The compressor operating time can be reduced to a minimum using the free cooling functionality that can be incorporated as an option. This considerably cuts both power consumption and operating costs.

Three operating modes are available: DX mode, free cooling mode and mixed mode. In mixed mode, cooling capacity is generated by means of simultaneous free cooling and compressor cooling. In this way, significant energy savings can be achieved even at moderate outdoor temperatures.

For noise-sensitive locations, the WPAmini is also available in a 'low noise' configuration. Here, the compressors are enclosed in a special sound-insulated casing, which lowers the volume to normal conversation level. The chillers can also be fitted with optional fan diffusers, which further reduce the noise level as well as electricity consumption.

The WPAmini can run in extreme climates and its operating limits range from -40 to +50 °C, depending on the model.

The switch gear cabinet is generously sized at the factory, ensuring sufficient space for optional electrical equipment. There is therefore no need for additional switch gear cabinets or extensions, with the interface problems these sometimes entail.

Furthermore, the WPAmini series satisfies the requirements of Ecodesign or ErP Directive Stage 2018.
