International. Seeking to improve efficiency and energy savings in one of its most important attractions (The Viking Splash River), the amusement park Legoland has incorporated a new system of frequency converters that would allow it to save up to 190,000 kWh per year.
The attraction consists of propeller pumps that send water into a large bathtub with curves and small bumps that create a rafting effect on the boat. The Danfoss VLT system will help control water use as strictly necessary, an important feature considering that this attraction requires the pumping of 1,800 liters of water per second.
Anders Christensen, who worked in Legoland's power sector, says that " we had problems when boats hit the wood and the flow of water could not be controlled; we have solved the problem by adjusting the frequency converters of the two pumps to 43.0 and 46, Hz, respectively, improving the performance of the attraction."
Thanks to the system designed by Danfoss, the electricity consumption of the Viking River Splash that normally per season was 444,000 kWh, after the installation of the frequency converters will be 250, 000 kWh.
