Energy consumption is always a key topic when looking to invest in a new tempering line. The reason is simple: the tempering process requires a lot of energy. So, energy costs are a major part of the tempering line’s operating costs. That’s why tempering equipment manufacturers keep making their lines more energy efficient – and also why you sometimes see unrealistic claims regarding energy consumption.
The automotive industry offers a good analogy. The trend has been towards cars that use less fuel and produce fewer emissions. Tightening regulations have been one of the main drivers of this trend. But fuel prices too play a big role in car ownership, so buyers are also becoming more demanding. The result is more environmentally friendly cars on our streets. But another outcome has been the cheating we’ve seen to achieve higher performance rates with lower investments.
Two years ago, we published a blog post called “The Volkswagens of the glass tempering business”to address the same issues in the tempering line manufacturing business. If you haven’t had a chance, check out that article for a real-life example.
Two years have passed and the issue is still here. We constantly facing situations where some people claims glass can be tempered using less energy than is required for glass heating according to the laws of physics.
