The "Wilo-Stratos GIGA" is another highly efficient product novelty launched by the Dortmund pump expert WILO SE. Now the sale of the first pump from the new high-efficiency series for the upper performance range in heating, cold-water and cooling applications started.

Approximately 8,000 kg CO2 per year and pump, as well as up to 85,000 euro electricity costs per pump installed can be saved with the "Wilo-Stratos GIGA" in 15 years compared to conventional uncontrolled pumps (based on the load profile "Blauer Engel"). The short pay-off period of less than two years also speaks in favour of installing the new high-efficiency series.

The series is a completely new development. For the first time glanded pumps are driven by extremely power-saving EC motors. The pumps' hydraulics is optimally adjusted to the motor technology. This is Wilo's competitive response to current and future customer and market demands. According to specifications of the manufacturer, the pumps reach a particularly high total efficiency based on a motor efficiency of up to 94 per cent at a nominal motor power of 4.5 kW. The motor's energy efficiency is based on a new high-efficiency drive concept, the High Efficiency Drive (HED) from Wilo and even outclasses the limit of the upcoming efficiency class IE4 (acc. to IEC TS 60034-31 Ed.1) that is set to be the best.

Thanks to the proven "red-button technology" and a display the pump guarantees a user-friendly operation. On the basis of optionally available IF-Modules to be integrated, different interfaces for Bus communication can be realised. External devices are redundant.

 "Wilo-Stratos GIGA" was awarded the "iF product design award" even before it was presented for the first time at the ISH trade fair in March 2011. The sought-after design award honours design quality as well as degree of innovation, environmental compatibility, functionality and ergonomics.
