70 to 80 percent of the world’s electric motors waste energy – even the relatively new ones.
This is not the case at Kartarpur Cold Storage in Karpur, India, near the Pakistan border. The company helps secure fresh food to the ever growing number of inhabitants in Indian cities – but with a total electric-motor energy-use that is 15-20 percent below industry average.
Kartarpur Cold Storage has installed VLT® frequency converters from Danfoss. The frequency converters control the storage’s electric motors via the power supply, so the motors run at precisely the speed necessary to obtain the desired effect.
“The electronic circuits delivered never need repair. We got about 50 frequency converters working and in the last six years maybe one of them has gone out of service. We never have to bother. It’s fit and forget,” says Kanwar Charanjit Singh, owner of Kartarpur Cold Storage.
40 years to build on
Danfoss has 40 years experience in India and sees fast-growing business opportunities as Indian cities now expand at an ever increasing pace. Estimates say that more than 200 million people will move to the urban areas during the next ten years and expected infrastructure investments approach 1000 billion USD.
“The infrastructure increase will cause a huge energy demand and, in power electronics, Danfoss has a perfect value proposition for the market. Cold chain is also going to require significant investments and here we are building competences and dedicated sales forces in the market to increase our coverage,” says Noel Ryan, President, Danfoss in India.
Electric motor installations can typically save up to 40 percent in energy consumption, if frequency converters are installed.
