Pfannenberg’s Signaling Devices compliant with the Seveso III Directive

/in

Enhance Industrial Safety: with the SIL/PL-compliant Signaling Technology from Pfannenberg, plant operators can guarantee standard alerting in accordance with the Seveso III Directive.

The EU Directive, Seveso III, is based on the catastrophic accident which occurred in the Italian town of Seveso in 1976 which prompted industrial companies that use dangerous chemicals to prevent and control such incidents. This can be achieved by installing appropriate industrial alerting and alarm systems.The amended Seveso III Directive has been enhanced and now stipulates that the authorities must do systematic assessments of all known plants with hazardous incidents as well as random inspections. Therefore, plant operators should, without fail, take the new legal situation into consideration when planning new plants – and check their existing plants for conformity to standards.

More industries concerned by the Directive
The Chemical Industry is no longer the only one affected by the Seveso III Directive legal requirements. Indeed, depending on the amount, type and risk category of the substances which are processed, the revised specifications can now be applied to metal processing and logistics companies or storage facilities for technical gases. A classification system (attachment 1 of Seveso Directive III) can be used to know how the new regulations apply to a company.

More safety with Pfannenberg’s sounders and flashing lights
An important requirement of the Seveso III Directive is to prevent failures and to limit the possible effects of incidents; for example, installing appropriate industrial signaling.

Pfannenberg’s SIL/PL Signaling Devices are therefore compliant to the EU specifications. Pfannenberg’s sounders and flashing lights are equipped with the safety-related parameters and can be integrated to your plant’s safety plan. Our DS Sounders or our Quadro Flashing alarms and PMF Series are, for example, particularly suitable for the compliant implementation of the revised Seveso III Directive.

“The deployment of our SIL/PL compliant Signaling Devices in industrial plants and companies reflects the consistent safety mentality of the planners and operating companies. Our products stand for more safety and reliability in the plants”, says Carsten Hippler, Product Sales Manager Signaling at Pfannenberg.

Pfannenberg Signaling Solutions comply to the European standard EN54-3

/in

Providing effective fire alarms has gained prominence in recent years. A major reason of this concern is the increase of ambient noise also called “acoustic smog”. The use of headsets, hearing protection and the consideration of deafness made the requirement of visual and acoustic alerts essential to save lives when a dangerous situation occurs.

European standard EN54-3

In order to meet these needs, The European Standard EN54-23 is effective since January 2014 and now sets requirements, testing procedures and performance features for audible alarms. The general requirements and specifications are made regarding the range of the audible alarm thus giving a certified area. Every certified tone has to be measured independently due to varying sound pressure levels.

In particular, the horizontal and vertical angle radiation characteristics of the signaling devices must be checked and defined for each individual tone allowing the total volume of area to be correctly alerted. This is an essential part of the approval which must be considered during the planning phase, as the number and location of devices is critical to meet approval.

Planning of audible signaling devices

Planning an audible alarm must be a complete process and further technical characteristics must now be considered:

  • The sound-pressure level [SPL] and the loudness (dB) of an audible alarm device is not identical for every tone. For planning requirements the SPL of the tone to be used on site always has to be taken as the basis for the plan. Never the loudest one available from the device.
  • The audible alarm device achieves varying dB depending on the radiation angle from the device. The maximum dB is at a 90° angle (head on) in most cases. The level is significantly reduced at the sides (0° / 180°) (see fig. 1: Polar diagram)

Specifically in the planning phase the respective signaling range of industrial sounders must be determined. This results from the existing ambient sound level, or background noise, at the project site in connection with the radiation characteristics. The technology used to create the sound also has to be checked and taken into account.

Pfannenberg visual and audible signaling devices

Pfannenberg PYRA and PATROL series of  industrial flashing sounders are the perfect option to comply with the highest European standards. Our experts assist our European customers to plan and design their signaling ranges with viable certified data and take into account their specific project conditions to determine and install the exact number of audible alarm devices required.

Pfannenberg’s enclosure cooling units installed in the Gotthard Tunnel

/in , , , , ,

Under construction for 15 years, the 35 mile long Gotthard tunnel located in Switzerland opened in 2016.

The Gotthard Base Tunnel impresses with many outstanding features:

  • It is the longest railway tunnel in the world at 57 km and its tunnel run, with all the transverse and connection tunnels, stretches over 154 km.
  • From 2016, passenger trains should have a top speed of 250 km/h, reducing the travelling time e.g. between Milan and Zurich to under 3 hours and should almost double the haulage capacity on the Swiss North-South Axis to 40 m tons of goods.

Operating a tunnel poses a huge challenge for engineers and operators. All products and solutions have to meet the highest requirements and have to work perfectly even under harsh ambient conditions. In particular, this applies to electrical enclosures and their thermal management, which are subject to extreme alternating pressure loads, temperature differences and are also exposed to dust and moisture.

In close collaboration, Swibox and Pfannenberg have developed a special climate control concept for tunnel applications. Robust Swibox electrical enclosures with a pressure body which was developed especially to protect the cooling circuit and the side mounted cooling units with integrated controller and heater from Pfannenberg guarantee a high system uptime which are situated, in the 176 cross passages amongst other places.

These electrical enclosure cooling units ensure that the thermal pressure of the electronic components integrated inside the electrical enclosures does not become too high and that they work safely and reliably throughout their whole service lives.

 

Electrical enclosures withstand every alternating pressure

The largest technical challenges were the high requirements to the system of protection of the electrical enclosure, IP65, and also the high alternating pressure load which is caused by the trains passing through. When entering the tunnel, the train pushes the air ahead of it, causing overpressure until the train passes by the cross passage where the electrical enclosures are standing. As soon as the train has passed, the overpressure transforms suddenly to a corresponding under-pressure.

All the electrical enclosures and the installed cooling units are exposed to the load of this alternating pressure of up to +/- 5 kPa. It had to be ensured that all devices can withstand this alternating pressure mechanically, simultaneously implementing the high system of protection.

It was possible to meet these requirements, thanks to the mechanical unit custom construction developed especially in cooperation with the company Swibox. This construction ensures a leak-proof separation of the surrounding (outer wall of the unit) and the inside of the electrical enclosure (unit inside), also under pressure load. A special feature here is the developed pressure body inside which the components of the inner cooling circuit are housed. Therefore, it was not enough to use reinforced sheet metal: the selection of a suitable material and the increased material thickness in combination with specially installed stiffening plates led to the desired compressive strength.

Climate control concept of electrical enclosures does not only mean cooling

Another challenge in tunnels is the ambient air. Large temperature differences ranging from -20 °C to +40 °C, maximum humidity of 100%, and ferrous abrasion of brakes, rails and contact lines in the ambient air increase the risk of corrosion and show how different a tunnel application is compared to standard applications.

Therefore, a special enclosure climate control concept had to be established for specifically this application. In addition to the cooling units, which are predominantly used inside the mountains (ambient temperatures up to +40 °C), Pfannenberg heaters also had to be installed in the portal sector (ambient temperatures to -20 °C). These heaters ensure that the temperature inside electrical enclosures does not fall below the so-called dew-point (the temperature that moist air has to drop to – by unchanged pressure – so that the amount of water dissolved in the air is precipitated as condensate). At the dew-point, the relative humidity is 100%; that means that the air is saturated with water vapour.

Pfannenberg’s new generation of controllers, designed especially for this project, were also installed. This is especially important to prevent unplanned failures and downtime and, by planning maintenance works in advance, to guarantee a high level of system uptime. The controllers are not only used directly inside the cooling units. The climate controller was also integrated into 500 other electrical enclosures without a cooling unit. This makes a temperature monitoring system possible, which, like the climate control units, can communicate with the tunnel control system and, if necessary, can be replaced with such, without having to reinstall the data transfer.

In 2010 the first cooling units were delivered to the company Swibox. In the meantime, all units have been delivered and will be installed one by one, together with the electrical enclosures, in the 176 cross passages of the Gotthard Base Tunnel. They have already been able to prove their reliability every day during the various test phases until the start of the scheduled railway operation on 2016.

Pfannenberg Illuminates the Tallest Christmas Tree in Paris

/in , , ,

Flashing lights make the “Place de la Concorde” shine

Hamburg, December 2012 – The tallest Christmas tree in Paris, which stands at 35 metres high, has been shining at the Place de la Concorde since the 6th December.

Equipped and illuminated with Pfannenberg 52 Quadro F12 flashing lights and inaugurated in an official opening ceremony by Paris’ mayor, Betrand Delanoë, the extraordinary light spectacle can be admired by inhabitants and visitors for a whole month longer.

Once again, Pfannenberg has proven that it is a competent partner in terms of art illuminations. As early as 2003, 20,000 Pfannenberg flashlights put the Paris landmark, the Eiffel Tower spectacularly in the limelight. Pfannenberg as a Hamburg company it was an absolute must to illuminate the Hamburg City Hall in 2004. And in 2008 9,500 flashing lights illuminated the Trinity Bridge, the television tower and the summer night sky in St. Petersburg.The French company SAF MAGNUM was commissioned by the City of Paris and is thus responsible for the Parisian Christmas Tree illuminations. The company is, amongst other things, a specialist for the illumination of events. Whilst searching for a manufacturer of flashing light circuit boards, SAF MAGNUM encountered the Quadro flashing light used in the Parisian Eiffel Tower which was produced by Pfannenberg. SAF MAGNUM then used this to build a prototype for the Paris Christmas tree.

For the flashing lights on the Christmas tree the circuit boards of the flashing light Quadro F12 were built into a plastic ball with a diameter of 50 cm. The ball is then, in addition, illuminated permanently from the inside by 12 red high-performance LEDs. The red permanent glow of the balls is made to sparkle by the Pfannenberg flash circuit board by means of a white flash once every second. This light generates 13 joules flash energy, 140 candela light intensity and an internal random generator creates a unique champagne pearl effect.
