Sinorix™ Silent Nozzle is an extinguishing nozzle made for Sinorix CDT and Sinorix 1230 extinguishing systems.

The nozzle has a specific linear design that smoothes the inflow of the inert gas into the protected area and

therefore reduces the noise.

All nozzles are drilled according to hydraulic calculations.

Each nozzle must be placed to its specific location within the distribution pipe network.

Sinorix™ 1230 extinguishing systems use containers with the agent FK-5-1-12, pressurized with Nitrogen to 42bar

at 20°C.

The pressure of the container is depending on the temperature:

- The container pressure will not exceed 53bar at 50°C

- The container pressure will not fall below 38bar at -20°C.

Engineering instructions Nozzle coefficients • Sinorix Silent Nozzle is designed to be used with Sinorix CDT Systems such as CDT-R, CDT-V, CDT-NXN and Sinorix 1230. Nevertheless, Sinorix Silent Nozzle can be used to upgrade existing unregulated Sinorix inert systems (IG-x-300, IG-x-200) as long as the nominal pressure in the distribution pipe network will never exceed 100bar.

Installation instructions • Check and clean the pipe network from dust and small particles which could obstruct the tiny linear diffuser holes during discharge. • Clean the thread on the nozzle and on the pipes. Remove any burrs. • Apply Loctite 577 or other thread sealant to the male pipe thread. • Fit the nozzle and tighten firmly. • The linear diffusers can be used to tighten the nozzle. The force applied to the linear diffusers shall not exceed 100N in any direction.
PAGE 6
Maintenance guidelines The nozzle is maintenance free. Nevertheless, special attention should be paid to keep the tiny holes in the linear diffuser unobstructed at all time. The linear diffuser holes should be checked for any dust or particles inside the linear diffusers. This is particularly important after the nozzle has been used for any discharge. The linear diffusers are attached by EO 24° connector to the T-Nozzle.
