SinorixTM CDT (Constant Discharge Technology) enables efficient extinguishing without pressure peaks. Thanks to the unique, by Siemens patented and VdS-approved valve technology, nitrogen is discharged with constant pressure during flooding. Thanks to the constant flooding, the piping network can be dimensioned smaller compared to conventional extinguishing systems and the overpressure flaps can be reduced by up to 70 percent. Thus, Sinorix CDT is especially suited for interior rooms where large overpressure flaps are hard to realize due to structural circumstances. Sinorix CDT uses pure nitrogen, a pure, color- and odorless natural gas. As a natural gas, nitrogen is environmentally friendly and does not leave any residues or decomposition products.
