  •     First and as of today only VdS-approved system with constant gas discharge

System overview Sinorix CDT

Sinorix CDT extinguishing solutions are based on a cylinder pressure of 300 bar. The innovative valve technology already limits the pressure at the cylinder valve to approximately 60 bar. In this way, it ensures that the extinguishing agent is distributed in the room constantly under consistently even pressure throughout the entire discharge time, allowing effective extinguishing without pressure peaks. Thanks to the even flow, overpressure flaps can be reduced by up to 70%. Sinorix CDT is therefore particularly suited for rooms in which large overpressure flaps are very difficult to deploy because of structural conditions. These include, for example, interior rooms or rooms with thick walls. With Sinorix CDT, overpressure flaps – which must be guided to the outdoors via a separate duct due to fire protection reasons – can be realized more cost effectively thanks to a reduced cross section. In addition, the piping networks can be smaller in size compared to standard extinguishing systems. The use of low- pressure range selector valves saves costs especially in larger multi-sector systems.

Sinorix CDT uses nitrogen, a pure, color- and odorless natural gas. As a natural agent, nitrogen is environmentally friendly and does not leave any residues or decomposition products. In addition, nitrogen is available everywhere, which makes refilling easier, more cost-efficient, and faster compared to technologies that use mixed gases.
