History of the Induction Radiator

The Infinity SAV company has been developing induction heaters for more than 7 years. Initially, the heater had the shape of an –®-shaped transformer and weighed 125 kg, its power was 5 kW. The cost price of this heater was very high. Therefore, we could not compete in the market.

But our induction heater had one advantage over competitors, this is the lack of scale formation on the walls due to the lack of a heating element as in tubular electric heating element. Further this feature has influenced reduction in cost of this heater.

For two years, the company Infinity SAV with great efforts tried to achieve a cheaper cost of production and acquired the necessary experience. We have manufactured a competitive induction heater. Its cost and weight was similar to the competitive devices.

It was a breakthrough in heating engineering, because it was a new way of obtaining heat through induction. This was economically justified, because the consumer was able to get a good product that did not require maintenance in the process of operation.

Known existing heaters must be disassembled and descaled on the heating element, which leads to a decrease in efficiency. The induction heater did not require such maintenance. The company Infinity SAV received a patent for the working model and technology and launched this induction heater.

During the year after the release of the product, other companies appeared that produced copied plagiarism of our model. These companies, through cheap labor, manufactured cheap induction boilers and became our direct competitors. The company that copied our device was able to obtain a patent for a utility model, based on our patent, changing only one trivial element in the device.

We started working to make the cost of the induction boiler even cheaper. As a result, we produced a mini boiler, whose weight was 3 kg per 5 kW, the price decreased by 2 times.

By installing capacitors in the device, we were able to increase the reactive current to 98%. This was the last point to reduce the cost of the device, it was the extreme limit. The next step was only to change the very essence of induction boilers. It was necessary to remove the thermal carrier in the device and to heat the air directly.

What does it give us?

– we avoid complex installation of the thermal system
– the thermal carrier is not necessary as well as pressure control in the system
– no circulating pump needed
– expansion tanks are not needed
– no radiator needed (cost is very high)
– do not need combs and couplings
– and most importantly, we get rid of the induction boiler and control system.

As a result, we have developed an experimental sample of induction radiator, which has heating gills (heated by induction field), a system of forced airflow (for the rate of air exchange in the room) and a grill tube.

The induction radiator consists of a large number of tubular gills. Gills are selected depending on the required power, depending on the room, which needs to be heated. One gill has a power of only 200W. If we need a power of 1 kW – we install 5 gills of 200 watts.

Advantages:

– fast heating rate
– energy saving
– easy and quick installation
– a set of any capacity by increasing the number of gills
– wireless control
– programming of temperature for an extended period of time
– switching on, switching off and setting the required temperature in each room remotely via the phone

How does an induction radiator work?

Each gill has a cast-iron cooler, which has a short closed loop, it is secondary. Primary is induction winding.
When the voltage is applied to the induction coil 220V at a frequency of 50Hz, an alternating magnetic field is formed, then the cast iron cooler is heated.
The cost of one gill does not exceed 10 USD.
