Surge protection in tall buildings

As water companies reduce water pressure in the domestic mains to reduce leakages, tall buildings are becoming reliant on booster pumps to provide water at sufficient pressure to enable normal daily living. This has revealed a potential threat – hydraulic shock, says Gary Wheatley from Wilo (U.K.) Ltd.

Energy savings from inverter drives in the efficient building Energy savings from inverter drives in the efficient building

As our energy reserves dwindle while costs continue to rise and as the spectre of climate change looms ever larger, it becomes ever more imperative to take action on energy savings. Recent legislation is now making the route of no-action impossible. Danfoss' John Martin, strategic business area manager, HVAC put the case forward for intelligent inverter speed control of fans and pumps in buildings.

A quantum leap in energy efficiency for house heating A quantum leap in energy efficiency for house heating

For decades it has been common practice to use circulation pumps in household central heating systems. The advantages are simple: a low noise level, an efficient wet runner motor and a maintenance-free design. Dr. Holger Krasmann, General Manager of the WILO Pump Group in Germany, explains the development of the technology and predicts its dramatic effects on energy consumption.
