Russian engineer develops electrically heated glass

20 Nov '20
Electrically heated glass is an innovative technology and a unique engineering solution. The technology in demand all over the world has spawned a lot of imitators. And it was created by Russian engineer Alexander Kostyuchenko.

The world has long lacked such technology - ever since panoramic windows, glass roofs and luxurious glass entrances appeared. How to keep warm in the house if you have huge windows instead of walls? And how to clean the glass roof from snow in winter without calling climbers every day? But there are also ships that sail along the Northern Sea Route, and planes that fly at a temperature of -60 °, and just our cars that turn into an ice block in winter. It would be much more convenient to operate all this if it was possible to prevent the formation of ice on them or to quickly defrost them. All these problems were solved by an engineer, a graduate of the Academy of the State Fire Service of the EMERCOM of Russia, Alexander Kostyuchenko, General Director of Thermo Glass LLC (a resident of Skolkovo), who himself developed the technology of electrically heated glass with an infrared heating element from scratch.

At the beginning of his entrepreneurial career, Alexander Kostyuchenko was selling infrared heaters, developing the production of polyethylene pressure pipes for water supply, but he was always interested in creating something of his own. So in 2008, the first line of infrared heaters of his design was launched, then still metal, with a ceramic heating element.
“I made the drawings and the profile myself,” says Alexander Kostyuchenko. “But there were analogues of such devices in the world, and I wanted to develop an alternative heating element. I combined three separate technologies, learned how to spray an electrically conductive metal - I got a heating element, and I was able to adjust its power with a laser. My heating element generates thermal energy in the infrared range, and this range accounts for up to 95% of the heat generated, evenly distributed throughout the electric heater. The result is absolutely transparent glass, which heats up from 0 to 300 degrees, depending on the tasks.”
The scope of application of innovative electrically heated glass is almost unlimited: flat glass electric heaters, double-glazed windows, and showcases, as well as glass floors, roofs, partitions, aircraft and ship windows. Yes, just windows in an ordinary city apartment! When it is cold outside, but heating was not provided, a warm window is very helpful. Or, for example, you have a wide windowsill and you decide to arrange a sofa on it. But in winter it blows from the window, and the battery cannot help in any way. A warm window creates a screen, while it is enough to heat it up to 25 ° C, that is, to the room temperature. The window is connected to the mains through a thermostat, which automatically maintains a certain temperature. The maximum heating temperature of double-glazed windows for apartments is 50 ° C.
“You get not just a window, but an air conditioning unit that provides heating in winter and coolness in summer,” Alexander Kostyuchenko praises his invention. “Coolness is ensured by multifunctional glasses that reflect heat rays from the street , so that they do not penetrate inside the house. ”
And also warm glass is a useful thing when attaching and insulating a loggia: in this case, batteries are not allowed to be installed, but about electric-heated glass units, no there is no indication.

In the off state, the heating glasses save heat due to the special design of the glass unit. The heating layer is a low-emission sputtering (K-glass) that retains heat in the room from heating devices and heated objects. In addition, the glass unit can be retrofitted with another heat-saving or multifunctional glass to achieve the best properties for maintaining the room temperature.
“We see prospects in smart glass,” Alexander Kostyuchenko shares his plans. “Smart glass is not only heating, but also variable transparency, and certain properties of sun protection. Now the production of ordinary glass is falling, while the production of smart glass is growing by 7% annually. ”
The company already has models in which transparent glass turns into frosted glass at the touch of a button.
In the near future - to expand production: “The market requires large glass units, not 2 x 3, but 4.5 x 2.5. It is difficult to do this in our squares. And there are many orders. So we need to buy a new production building or enter into collaboration with the largest manufacturers of double-glazed windows in the country. ”
Patriot to the bone, Alexander Kostyuchenko is not going to transfer production to China, although he plans to make his own project international.
“We supply products to Europe, in particular to England, we have opened a joint venture in Poland, and now we are opening in Belarus,” he says.
