Economical design with high-efficiency pumps from Wilo

When designing larger construction projects, choosing the right heating, water and sewage components is crucial for ensuring that the system runs smoothly.

By integrating the innovative products from Wilo into your building design, you ensure at an early stage that the property is both energy-efficient and cost-effective in later operation. Depending on the sector, pump types such as the Wilo-Stratos MAXO, the Wilo-Helix 2.0-VE or the Wilo-Actun ZETOS use only a fraction of the energy of conventional, uncontrolled pumps.

With the Wilo-Select 4 online tool, you can check in just a few steps which of our products are suitable for your building. As an alternative, our Wilo Service team can get an impression of your site themselves and make a recommendation.

By relying on Wilo systems, you protect the environment, the wallets of future tenants and the nerves of the building developer. It’s a real win-win situation!

Five stars in energy efficiency for the Sheraton Nanjing Kingsley Hotel

Over the course of comprehensive renovation and modernisation measures, the entire air-conditioning system of the 41-storey building was replaced and the energy-efficient standard pumps of the Wilo-Atmos GIGA-N series were installed. Their high overall efficiency ensures an energy-saving refrigeration circuit in trouble-free continuous operation at significantly reduced electricity costs.

“Compared to other energy-saving measures, switching to the Wilo standard pumps was the simplest and most effective one”, states Mr Lin, equipment supervisor of the hotel. “Moreover, the payback period is just two and a half years. This has clearly exceeded our expectations!”

In figures, this means 240,000 kWh of electricity savings per year and 22.8% less energy consumption than before the conversion. As a result, the five-star resort is now also in the top class when it comes to saving energy!
