The Second Most Electrically Efficient Sic Heating Elements Float Glass

THE SECOND MOST ELECTRICALLY EFFICIENT FLOAT GLASS HEATING ELEMENTS IN THE WORLD

For those companies not able to take advantage of the most electrically energy efficient float elements we offer the second most efficient. The 28mm diameter cold end float element is the most efficient but the cold end is too large in diameter to fit into the terminal hole of some roof modules. For these roof modules we offer the 19mm cold end. The second most efficient float element in the world.

COLD ENDS ARE LOWER IN RESISTANCE

The energy efficiency is obtained in the cold ends. The cold ends are 19mm in diameter. The same as other float element manufacturers. Our 19mm cold end provides a larger surface area over which the electrons flow because it is a solid rod and not tubular, therefore it is lower in resistance. The 19mm cold end is manufactured of low resistance Beta silicon carbide. It decreases in resistance with an increase in temperature.

Our U.K. competitor with one piece construction 19mm solid cold end is manufactured of high resistance Alpha silicon carbide impregnated with silicon metal. It is high in resistance at room temperature and increases in resistance with an increase in temperature. The low resistance cold end reduces the amount of the electrical power wasted in heating the roof module. The perfect cold end would have zero resistance. The Starbar 28m and 19mm cold end are close to perfection.

LONG LIFE HOT ZONES

Type W three-phase hot zones are manufactured of high purity, high density, alpha silicon carbide and selfbonded by recrystallization. They have a high density of 2.50 grams per cubic centimeter. This provides high structural strength and minimum porosity, and therefore slow aging characteristics. They have an average campaign life of 15 years.

SUPERIOR WELDS

Before welding the cold end to the hot section we serrate the surface of the butt end of the cold end. This makes our welds stronger and more reliable. RELIABLE WELDS AT BRIDGE The bridge is manufactured in 2 pieces to get a better electrical connection and superior welds to the three hot section legs.
