The innovation consists on a High Efficiency Voltage Variator system which depending on water temperature and demand, would turn on or off cooling tower's fans. If water is cold and on low demand, fans would stay off; if water is hot and / or on high demand, fans would have turned on to cool it down, thus using electricity only when needed. This technology emerged when the operator of the fans, who was previously turning them on or off according to his judgement, suggested to the master black belt, that there was an improvement opportunity. The productivity team came and mapped the whole process, and using six sigma and lean tools, they detected that the process could be improved. Finally Evan Camps and Jorge De León participated in the creation of the innovation and implemented it. Linde’s mission is to make the world more productive and this innovation is well aligned; this innovation relates to a sense of mission because it has a broader social context, it seeks to reduce environmental impact rather than being merely oriented to productivity.
Motivation at the end of the day comes from sustainable development goals appointed by Linde and the employees' desire to reach them. "At Linde we have appointed 6 sustainable development goals and 2 of them are directly related to my department", said Armando Villarreal.
In 1 year, this innovation helps saving 386,400 kilowatts, equivalent to stop emitting 252 tons of CO2, having a big positive impact on environment and society. This benefit contributed to Linde's 2017 electricity savings of 78,590 megawatts, equivalent to the electricity consumption of 8,700 homes during one year.
This reduction on electricity represented savings by year of $19,320 USD, having a positive impact on the business.
In one year, this innovation helps saving 386,400 kilowatts, 6% of the plant's electricity consumption, equivalent to stop emitting 252 tons of CO2, having a big positive impact on environment and society.
