You’ve seen them in images and videos from around the world..but how do these massive wind turbines actually generate electricity? The principle is the same as the wind mills of old , except that the windmills used the energy to crush corn or move water for irrigation.
For many of us looking to save energy , especially on hot water…This short video shows exactly how this system works. In South Africa, we are fortunate to have year round sunshine ( well mostly) and this is certainly a viable option as part of a long term energy saving strategy.
If you own a business that has refrigeration as an integral part of every day operations , like a supermarket , restaurant , coffee shop , cold storage , butchery, dairy etc, then you need to find a safe and effective way to cut your refrigeration running costs.
This simple device called an E CUBE , is a revolutionary product that was introduced to the world around 2007.
It simply changes the way that control systems function by receiving data based on the products inside the fridge, rather than the fluctuating air temperature.
So , simply put , if the food in the fridge doesn’t get warmer , then why should your fridge come on?
These were installed in the entire Cold Storage Facility at Johannesburg Fresh Produce Market after independent tests showed that the E CUBES reduced consumption by around 20%.
