Silent Nozzle Extinguisher Does Not Harm Hard Disks

27.09.2011
Siemens has developed a very quiet nozzle for gas extinguishing systems.

The system is especially suitable for use in computer centers that store sensitive data. That’s because loud noise can cause hard disk drives to fail. However, the noise created by the Sinorix Silent Nozzle remains below the level that would endanger hard disk drives.


As is the case in many industrial facilities and archives, fires at computer centers are generally not extinguished with water but with gas. If a fire breaks out, the extinguishing systems flood the room with natural gases such as argon, nitrogen, or carbon dioxide within seconds, displacing oxygen in the process. Alternatively, chemical extinguishing agents can be used. These extinguish fires by extracting heat (energy) from the flames. The discharge of gas by conventional nozzle systems is very loud and can reach noise levels of 130 decibels or more, which is equivalent to a fighter jet taking off. In rare cases, computer center operators have noticed that such extinguishing systems have caused hard disk drives to fail temporarily. Studies have confirmed that this failure was the result of the hard disks’ sensitivity to noise.

The new nozzle from Siemens Building Technologies is designed to keep the noise level below 100 decibels, as this comparatively low noise level doesn’t damage hard disks. The nozzle also makes it possible for the operator to choose the direction in which the gas will be discharged so that the sound waves will have a minimal impact on the hard disks.

The nozzle can use the natural gases nitrogen or argon, and a similar nozzle concept is currently being developed for chemical extinguishing agents. The flooding times are identical to those for conventional nozzles. The new nozzle is fully compatible with the Sinorix gas extinguishing system and can also be retrofitted into existing facilities.

Im Focus: Attoseconds break into atomic interior

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.

In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...

Im Focus: Good vibrations feel the force

A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.

By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

Im Focus: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
