This efficiency is based on the efficient driving philosophy of Vaille AG, Germany, which is said to exceed the limits of the IE4 efficiency class. June 16, 2011, the EU new regulations on motor energy efficiency will come into force. Efficient drive with integrated frequency converter, combined with DC motor technology, control range than the traditional electronic control pump three times. Improved adaptability to changes in hydraulic system power requirements. Pluggable IF modules are available for a variety of interface bus communications. BACnet, Modbus, CAN, LON, and PLR mean supporting all current market standards. The Wilo-Stratos GIGA range is suitable for heating, cooling and cooling systems. The allowable liquid temperature range is -20 ° C - 140 ° C. In climate control applications, the series offers better corrosion protection due to the electrophoretic coating. Wilo-Stratos GIGA series first high-efficiency pump diameter DN40, motor rated power 4.5 kW, available in September 2011.
