All critical components of HS PTV that exposed to the airstream are ferrous construction to withstand high temperature conditions.Belt and bearings are protected from the air stream by enclosing them in a ventilated tube. Specially designed roof mounted exhaust fans would mechanically vent heat and smoke under emergency fire conditions. A spring load, fusible link activated device automatically opens dampers when temperature at the fan reaches 165 F   Powerful and combined with rich content technology. These effects were created during the machining of steel box: all the details that compose .   The Silverstone Tourbillograph Full Black is a self-winding chronograph with column wheel and tourbillon. First of its fragility. The dial, also black, has a shiny appearance due to rhodium, the Arabic numerals are visible or blurred, playing a tone on tone effect. Its exhaust vibrates at 28,800 vibrations hour. The rotor is supported on bearings and ceramic column wheel that controls the chronograph displays elements   Alternating with shiny satin. The unique coating which subsequently form, caused by a reaction to the plasma consists of a multilayer structure characterized by colors that change with the reflections of light. The 48 members of his cage skeleton are intertwined with each other and the total weight of the mechanism is reduced to only 0. The domed sapphire crystal is of extraordinary size 42 mm in diameter.   Do you know what Iris? Rainbow. This building, called the tourbillon Cintr integrates into the chronograph complication despite the use of a large diameter wheel. The reduced number of elements, lightness, and the double-deck provides stability and rigidity to the building. Overall, the engineering know-how has acted by abolishing the intrinsic weaknesses of the tourbillon. The Tourbillograph Full Black has indeed passed the test Chronofiable .
