Wilo-Stratos GIGA is the solution for optimising the cost of heating, cold water and cooling systems in new and refurbished buildings in the Hotel, Sport & Leisure sectors. As the first high efficiency glanded pump, it operates reliably with the minimum of effort. Compared to conventional uncontrolled pumps, Wilo-Stratos GIGA saves up to 70% energy – per pump, per year, and this adds up to a saving of around 8 tonnes of CO2. This is possible because Wilo has designed every component, from the drive, through the electronics to the hydraulics, to operate at the highest level, while perfectly coordinating each of the components with each other.
Fast and controllable: the motor
In the High Efficiency Drive (HED), Wilo has developed a pump drive with a motor efficiency that far exceeds IE4, the most stringent class defined today. This can be traced back to the choice of EC motor technology. Among other features, these motors have almost no rotor-related losses. The HED for Wilo-Stratos GIGA can be as small as a third of the size of a conventional asynchronous motor with the same rated motor power. By reducing the motor size, it is possible to achieve higher speeds without this having a negative impact on the components' service lives.
Simple and precise: the electronics
Thanks to the tried-and-tested "red-button technology", Wilo-Stratos GIGA can be handled simply and conveniently with just one button for a control element. Alternatively, the device can be controlled via infrared connection to an IR monitor, an IR USB adapter or a building management system.
Small and versatile: the hydraulics
The hydraulics for Wilo-Stratos GIGA are designed to ensure the maximum possible efficiency in the system. Both the housing and the three-dimensional impellers are shaped very precisely into a geometric form that maximises flow and minimises impedance. The powerful drive increases the rotational speed, which reduces the size and weight of the hydraulics.
Efficiency pays off
All these benefits add up to unbeatable energy - and cost-efficiency. Compared to the Wilo IL-E series, Wilo-Stratos GIGA uses about 31% less energy per year – and 70% less than comparable uncontrolled pumps. With 6,000 operating hours per year and an energy price of 0.22 EUR per kilowatt hour, the GIGA begins to pay for itself after just one year.
