Driven by the motor industrial process consumes large amounts of power, even smallimprovements can also bring great benefit. Low voltage converter has been installed ABB by controlling the motor power consumption, can reduce 2.2 tons of carbon dioxide emissions per year.

ABB has a synergistic energy-saving broad product portfolio, which includes advanced process control system and automation products and electrical equipment,but the most remarkable energy-saving results should be the inverter can improve themotor efficiency.

Motor everywhere, they drive equipment energy consumption accounted for the total global consumption of 1/4. With adjustable speed motor frequency converter, power consumption can usually be decreased by 30%, thereby greatly reducing the cost and reduce greenhouse gas emissions. Whether in civil, commercial or industrial areas,ABB inverter are helping users "use less, do more".

In 2010, low-voltage inverter has been installed ABB save enough electricity to meet the 65000000 European family annual demand.

For example, in Sweden, thermal power plant operator M larenergi AB ABB in anenergy saving audit assessment, decided to install adjustable speed motor frequency converter to control many within the plant operation.

ABB provides 8 sets of medium voltage inverter, part of which is used to replace theoriginal resistance speed motor control system. This improvement eliminates theresistance heating caused by the great electric energy loss, make the factory every year to multiple output power of 35000000 kwh, which is equivalent to increase capacity by 5%.

The control is more outstanding

Many factories, whether or not necessary, many motor driving pump and fan has beenrunning at full speed. These devices by the throttle control -- it is like when the brakestill fill the throttle loss, both equipment and waste a lot of energy. In addition, the resistance and the retaining ring motor can also be used to control the flow velocity,but this approach also waste energy.

Adjustable frequency converter provides a new efficient and energy-saving methodfor motor control. Let motor inverter can according to the actual needs of the use of electricity, can reduce energy waste and equipment loss. In addition, the inverter can also save raw materials through improving the process quality.

In addition to save electricity, the device also reduces CO2 emissions of M larenergi thermal power plant, and improve the reliability of district heating network. On Mlarenergi thermal power plant operators, the best news is, the investment returnperiod is only a short span of 12 months.

It is estimated that the low voltage converter in 2010 has been installed ABB save 260000000000 kilowatt hours of electricity, enough to meet the 65000000 Europeanfamily annual demand; while also reducing emissions of 2.2 tons of carbon dioxide, is equivalent to let Europe about 55000000 cars off the road for a year.

Human society is faced with reduced environmental impact and meet growing demand for electricity this dual challenge, ABB converter will make a long-term positive contribution.
