It all starts with small aluminium bars called sows. To manufacture our aluminium radiators, we use high-quality raw material with increased requirements for a group of elements of chemical composition according to the Armatura standard based on the PN-EN 1676 standard. We test this composition for each smelting process using a Spectromax type spectrometer and check the crystallographic structure using a microscope.
Then the aluminium sows are placed in a melting furnace, where they are melted at a temperature of about 850°C. After that, the material is transported to the heating furnaces installed at the casting machines. Once the process is over, the casts are strictly controlled, both visually and with the use of an X-ray machine. Later, after machining, which includes a series of operations connected with precise grinding of the surface, welding the plug, threading, and bolting sets together, we check the tightness of our radiators.
The next step of the manufacturing process is connected with protecting the radiators against corrosion during the fluorozirconic and anaphoretic treatment. Thanks to anaphoretic varnishing, we obtain a durable coating highly resistant to corrosion. The last stage involves covering the radiators with an electrostatic powder coating and placing them in furnaces where the varnish polymerises (at a temperature of around 200°C).
After that, the radiators are packed and transported to our clients.
Get to know the 4 key arguments that will convince you to choose the aluminium radiator manufactured in our factory in Nisko.
The thermal output of the radiators for an average temperature of 50°C is even over 90% higher than in the case of popular steel panel radiators having the same weight.
Fast heating-up: thanks to low unit weight and excellent thermal conductivity of aluminium.
The radiators have a special shape of air outlets, thanks to which heated air is directed directly to the centre of the room and not upwards, which prevents it from bouncing off the windowsill.
