BITZER provides spare parts with QR codes

Another measure in the fight against product piracy: the specialist for refrigeration and air-conditioning technology BITZER has added QR codes to the packaging of its Original Spare Parts. By scanning the code, users can check the authenticity of their products plus obtain further relevant information.

Product pirates not only sell counterfeit compressors, but also fake oils and fake spare parts. BITZER has been monitoring this development and continuously improving measures to confront this known problem and protect its customers. BITZER compressors have been equipped with QR codes for an authenticity check for years; this service will now be phased in for most BITZER Original Spare Parts as well.

Only original is safe
The secure QR code protects against counterfeits as it contains information that only BITZER can provide. Each QR code is linked to the specific part and the package it comes in. When scanning the code, customers receive the respective part description and picture, part number, BITZER specific protection data, as well as direct access to the relevant documentation in the BITZER spare parts software EPARTS.

Technologically sophisticated machines like compressors need perfectly tuned components to continuously guarantee high performance. Each spare part has to perfectly match the running system. BITZER Original Spare Parts are designed together with compressor development and thus are always considered state-of-the-art technology. They come with a parts warranty and match the highest operational standards of BITZER compressors, and fast supply is guaranteed by BITZER Global Logistics Centres.

Small, but decisive
The devil is in the details: first signs of counterfeits are often already visible in the packaging. These first hints may include poor alignment of the logo print, different colour schemes of the BITZER logo or a lower-quality cardboard box. Fake spare parts themselves show risks of low performance due to wrong dimensions as well as poor materials, machining and finish.

The use of non-original spare parts puts compressor safety and reliability at serious risk: they can lead to significant damages and could cause the compressor to break down. Therefore, BITZER recommends not to use such components. Customers are advised to contact their nearest BITZER office if they doubt the originality of their supposed BITZER spare parts or upon discovering counterfeits.

Engine Blades for the aerospace industry

One of the most crucial components of a working engine system is its engine blades, such as turbine or compressor blades. A turbofan engine, for example, has many parts: at the front, the fan draws in the air and directs it into the compressor, which is composed of several blades arranged in a row and decreasing in size towards the end of a narrowing tube. Using a rotational movement, the suction air is compressed to up to a thirtieth of its volume, which in turns compresses and heats the gas. The air is then fed into the combustion chamber where it is mixed with injected kerosene and burned. The resulting energy propels the high-pressure turbine where the turbine blades driving the compressor are installed. The downstream low-pressure turbine is also set in motion using this energy. The low-pressure turbine consists of longer turbine blades and is directly connected to the fan. The turbine ensures that the fan rotates. The fan not only sucks the air into the interior, but past the compressor and the turbine. The cold air, which is fed past the interior, generates the greatest propulsive force. The process inside the engine merely ensures that the engine remains running. So the exhaust gas flow produces 20% of the propulsion and the fan, 80%. Both the turbines and compressor blades are subject to high temperatures and pressures. Manufacturers have therefore implemented strict regulations for the production and processing methods used.

The engine blades used in the aerospace industry are usually made of materials that are difficult to machine and have a low tolerance that must be met to obtain the ideal air flow and maximum wear resistance. These components are exposed to extreme temperatures of up to 1,000°C. This means that the blade surfaces also have to be of the highest quality and optimally adapted to the conditions in the engine. OTEC has developed a special process to improve the efficiency and safety of engine blades and produce fewer defects.

Smoothing the air foil, i.e. the blade body, has a positive impact; depending on the required result, the surface can be smoothed to values of up to Ra < 0.2 µm in a few minutes, increasing blade efficiency. The material is removed evenly and only a minute amount is taken from the surface. Repairing the leading and trailing edges with precision rounding can reduce the quantity of rejected parts. The upstream machining process, e.g. blasting, can damage these edges. OTEC’s method enables them to be rounded to a given radius and hence repaired. The rounding process is very precise and involves minimal material removal.

Deburring the root helps to improve safety by preventing the blade from becoming caught in the disc. Surface treatment not only prolongs the service life of the blades but increases their efficiency. This is also the ideal preparation for coating the components. Smoothing and rounding the engine blades is possible in a single operation thanks to OTEC’s innovative stream finishing process.

In the stream finishing process, the blades are clamped into the machine and lowered into a container of abrasive. Processing is carried out by both the rotation of the container and the movement of the workpiece in the media flow. The flow to the blades in the machine is clocked, i.e. the alignment angle of the workpiece changes at frequent intervals. This means processing can be precisely aligned to specific points on the workpiece, achieving a smooth surface and precise rounding without altering the shape of the blade. An important benefit of OTEC’s process is the ultrashort machining times compared to conventional processes. Depending on the size and initial condition of the workpiece, the surface treatment of engine blades takes between 2 and 20 minutes. As the blades are clamped individually, no damage will occur to the workpiece surface. All processing steps can be carried out in one machine. The SF-5 stream finishing system can process up to five engine blades at once, ensuring high output and cost efficiency. Tests conducted after OTEC processing show positive results for residual stress, fatigue strength and fluorescence control.

Engine blades are not only used in the aerospace industry, but also in the power sector. The surface treatment of blades from energy turbines can also be carried out in OTEC machines.

codia setzt seit zehn Jahren auf den PDF Compressor

Der PDF Compressor bereichert die Produktlinie von codia bereits seit zehn Jahren, indem Kunden mit der Lösung von Foxit hochkomprimierte, volltextdurchsuchbare PDF/A-Dateien innerhalb ihrer elektronischen Aktenführung erzeugen können.

codia konnte bereits über 300 öffentliche Verwaltungen auf dem Weg zur eAkte unterstützen und das Enterprise Content Management System d.3ecm von d.velop einführen. Wenn es bei den Projekten darum geht, Bestandsakten zu digitalisieren, empfiehlt der eGovernment-Spezialist den PDF Compressor von Foxit Software. Die praxiserprobte Lösung stammt aus dem Hause LuraTech. 2015 wurde aus LuraTech die Foxit Europe GmbH und gehört damit nun zu Foxit Software, die schnelle, günstige und sichere PDF-Lösungen für Endanwender bis hin zu Entwicklern anbietet.

PDF Compressor fördert Effizienz auf der Anwenderseite

Der PDF Compressor wird direkt in die fachspezifischen Lösungen von codia integriert bzw. ist ein Bestandteil von d.3ecm. „Wenn im Rahmen eines eAkten-Projektes große Papieraktenbestände gescannt werden müssen, wächst das zu speichernde Datenvolumen schnell auf mehrere Terabyte an“, sagt Philipp Perplies, Prokurist der codia. „Somit ist ein hoher Speicherbedarf notwendig, der zusätzliche Kosten verursacht, die IT belastet und durch hohe Ladezeiten zu Akzeptanzproblemen beim Anwender führt. Diese Problematik löst der PDF Compressor, indem er gescannte Dateien in hochkomprimierte, volltextfähige PDF/A-Dateien wandelt.“ Diese steigern die Effizienz der Anwender, denn die Dateien stehen aufgrund ihrer geringen Größe sofort zur Verfügung und können problemlos per E-Mail verschickt werden. Darüber hinaus sorgt das PDF/A-Format dafür, dass die Dokumente über Jahrzehnte hinweg beweiswerterhaltend speicherbar sind.

Farbige Dokumente so klein wie Schwarz-Weiß-Dokumente

Insbesondere bei farbigen Dokumenten ist das Kompressionsverfahren des PDF Compressors ein ausschlaggebendes Argument. Sie sind nach der Verarbeitung durch die Lösung von Foxit so klein wie ein vergleichbares Schwarz-Weiß-Dokument im TIFF-G4-Format, ohne dass die Farbinformationen verloren gehen. Diese müssen im elektronischen Dokument aufgrund der Nachvollziehbarkeit erhalten bleiben, denn in Verwaltungen versehen oder unterschreiben Mitarbeiter Papiere oft mit unterschiedlichen Farben. Auch auf Plänen, beispielsweise von Bau- und Katasterämtern, sind regelmäßig Farbinformationen hinterlegt.

Neben der Stadt Wuppertal, wo derzeit das Jobcenter seine Bestandsakten und den Posteingang digitalisiert, gehören unter anderem die Stadt Selm und die Stadt Emsdetten zu den Referenzkunden, die auf d.3ecm und den PDF Compressor setzen.

New FKM material specifically to meet the demands of the oil and gas industry

With the newly developed FKM compound Vi 900, the seal manufacturer C. Otto Gehrckens presents a high-performance product innovation for use in the petrochemical industry. The material has proved its suitability as a dependable elastomer seal even under the most demanding conditions, complying with NORSOK test standard M-710 and also passing the hardness test with the best possible rating of 4x ‘0000’, without showing any damage whatsoever. Vi 900 is therefore ideally suited for use in production sectors which, as a result of the danger of explosive decompression, impose especially high demands on the seals used.

The special feature of this new product development is its outstanding stability under low temperatures. With a TR-10 value of -40°C, Vi 900 is suitable for the coldest applications, right down to -50°C and, as well as complying with the NORSOK standard, it therefore also complies with American standards API 6A and 6D for oil and gas installations. According to the manufacturer, combined with an extraordinarily good cold compression set this high-performance material sets new standards in relation to AED (anti-explosive decompression) and RGD (rapid gas decompression) seal materials.

A further plus point for this new FKM compound is its excellent resistance to a wide range of specific media and chemicals, from mineral oils to aliphatic, aromatic or even chlorinated hydrocarbons and also to acids in various concentrations and weak alkalis. And as the material is also characterized by very low gas permeability, a wide range of applications is possible. Vi 900 is used as a seal material in valves, ball cocks, pig traps or slider valves in production areas where the very highest levels of reliability and the best possible quality with respect to explosive decompression are required, above all in the petrochemical industry, in compressor construction and also in compressed air preparation. This new material is available with immediate effect.
