Sinorix CDT (EN)

Sinorix CDT (Constant Discharge Technology) is a regulated extinguishing system that uses nitrogen or argon as an extinguishing agent. A conventional unregulated extinguishing system follows an exponential discharge characteristic with a significant peak at the beginning of the discharge. The Sinorix CDT technology consists of a cylinder valve with a pressure-regulating function which discharges the gas into the flooding zone at constant mass flow throughout the entire flooding time. This eliminates the peak at the beginning of the discharge and thus lowers the maximum noise level. Thanks to the constant mass flow, the cross-section of the pipes can also be dimensioned smaller than with conventional unregulated extinguishing systems, and the size of the overpressure flaps can be reduced by up to 70%. Thus, Sinorix CDT is especially suited for interior or cellar rooms, where large overpressure flaps are hard to install due to structural conditions.

Sinorix CDT is applicable for both single and multi-sector systems and can be tailored for a wide range of applications. It is possible to position the cylinder battery either centrally or decentrally.

Sinorix CDT uses the inert gases nitrogen or argon for extinguishing. Inert gases extinguish a fire by reducing the oxygen volume concentration in the protected area – to a level at which the fire can no longer burn. Nitrogen and argon excel thanks to their excellent extinguishing properties for fire classes A, B, C and D.

Nitrogen and argon are harmless to the environment and safe for people. Ambient air, for example, naturally contains the two gases. Depending on the risk of fire and national guidelines, Sinorix inert gas extinguishing systems are designed as people-safe systems.

Nitrogen and argon have poor electric conductive properties and are chemically inert. As a result, they do not create any harmful reaction products. This allows optimal protection of critical applications with electric and electronic equipment like data centers or server rooms.

Easy refilling minimizes the downtime of the extinguishing system after a discharge – and also reduces costs.
