In processing plants that require the highest levels of hygiene, sterility and leak-tightness, excessive overpressure or vacuum can occur due to a wide variety of causes. In such cases, rupture discs protect both vessels and pipelines from deformation and further damage. Above all, they protect the lives of the employees who work in these plants. The primary goal here is to provide optimum protection for these systems, taking into account technical and economic aspects, while at the same time minimising system downtime.

Excessive overpressure can occur in almost all production areas and processes in the pharmaceutical industry. If the pressure exceeds or falls below the limits defined for the process, serious damage can occur to the respective plant components. Possible consequences include production stoppages and significant economic damage. Therefore, in situations where the pressure exceeds or undershoots the permissible operating range, a reliable and fast-acting pressure-relief device is essential.

Many operators in the pharmaceutical industry already use REMBE high-performance rupture discs in their processing plants – because the advantages of these pressure-relief devices ensure permanently safe operation:

• Thanks to their leak-tightness, our rupture discs prevent the escape of process media
• The complete cross-sectional release of the burst element provides immediate pressure relief for the system
• REMBE rupture discs have a response time of mere milliseconds

In order to customise the design of our rupture discs for each customer, numerous factors must be considered ahead of time. Reliable and economical rupture discs are not standardised products. Instead, they are individually adapted to the respective process conditions, designed accordingly and then manufactured specifically for the customer's applications. Numerous parameters are taken into account to ensure optimal performance.

Carrying out bolting operations at height runs the risk of danger to those working beneath dropped objects. Enerpac introduces a lightweight solution. The Enerpac DSX-Series Aluminium Square Drive Torque Wrenches are safe, easy to use, tools designed for medium duty use when working at height.

To help to reduce dropped-object incidents when working at height, the five models in the series feature a built-in connection point to safely tether the tool to a work belt or bag. A standard ergonomic safety handle also helps to prevent injuries or near misses from loss of tool. When it comes to operator protection, a fully enclosed drive prevents operator contact with moving parts inside the tool.

Made with a high-strength aluminium body, the CE Approved Enerpac DSX-Series Aluminium Torque Wrenches are lightweight and easy to use—important factors when working at height. Another feature that makes the tool simple to use is a multi-direction 360 x 180° high flow aluminium swivel that helps prevent twisted and tangled hydraulic hoses. To help make operators more efficient on-site, the wrenches feature a fine-tooth ratchet that prevents the tool from locking on, a 35-degree rotation angle that assists with repetitive bolt tightening tasks, and a retained push-button quick release.

Additional key features include torque output ranging from 191 to 32.617 Nm, compact nose radius for tight locations, tool accuracy +/- 3% and ATEX approval for bolting projects in in explosive atmospheres.

The Enerpac DSX-Series Aluminium Square Drive Torque Wrenches are now available through Enerpac distributors. For more information visit www.enerpac.com.

With increasing demand for lightweight, more portable tools, Enerpac has developed the RACH and RARH - Series aluminium hollow plunger cylinders. Up to 150-ton capacity cylinders provide engineers with a lighter, more portable tool for applications such as tensioning, pulling and pull testing.

Enerpac RACH-Series Single Acting Aluminium Hollow Plunger Cylinders (sometimes called centre-hole cylinders) have a threaded collar inside the plunger, allowing attachments or threaded rods to be connected to the hydraulic cylinder. They provide a lighter alternative to other tensioning and pulling systems. The RACH-Series includes cylinder capacities ranging from 20 to 150 T, and 50 to 250mm stroke. All RACH-Series cylinders are rated for up to 10,000 psi (700 bar).

RACH-Series cylinders are single-acting and use a high-strength return spring for rapid retraction. All are equipped with bolt-on hardened steel saddles and a steel base plate for increased durability. Combined with a lightweight Enerpac hand pump, engineers now have a highly portable tension and pulling tool set for remote working.

For an even quicker and more controlled retraction, the RARH double acting models are available. Featuring the same advantages of the RACH, they are more lightweight due to their lower collapsed height.

“The Enerpac RACH-Series offers outstanding durability; their design enables longer service life and increased push/pull capability,” says Senthil Vijayakumar, Cylinder Product Manager at Enerpac. “Hollow shafts offer great versatility in pulling and tensioning applications, which combined with the lighter weight of aluminium provides the perfect tool with a longer service life and reduced maintenance. All of which means that users can confidently take on the most demanding tensioning and pulling applications with the RACH and RARH – Series cylinders.”

Typical applications for the RACH and RARH - Series include rod and cable pulling and tensioning, rock-bolt testing, as well as shaft removal. All the cylinders are compatible with a broad range of pumps, from the economic hand pumps to the most sophisticated, split flow pumps and the Enerpac EVO-Series synchronised lifting systems.

Enerpac announces a new Ultra-Flat hydraulic cylinder series for those projects with small working space, starting at just 2,8 cm, but large lifting requirements up to 1000 ton. The CULP-Series with lifting capacity 10 – 50 ton, and CUSP-Series 10 – 1000 ton, are designed for applications where high lifting forces are needed in confined spaces.

With a 700 bar max operating pressure, the Ultra-Flat cylinders provide a 7 – 17 mm stroke, and are designed to withstand up to 4% side load at full lifting capacity. The CUSP-Series has an integrated tilting function up to 4 degrees, and a 6 – 10mm tilted stroke.

Safety is critical to all Enerpac products. CULP Ultra-Flat hydraulic cylinders are equipped with an internal stop ring that prevents the plunger from accidentally dropping at the end of its stroke. CUSP Cylinders have a “Red Line” as visual indicator to the operator when the maximum stroke has been reached. The CUSP-Series’ tilting plunger can be adjusted enabling equal distribution of load over its full surface. Even at maximum tilted position, most models will have a straight lifting stroke of 10 mm.


All Enerpac cylinders are built to last. In addition to low maintenance requirements, the Ultra-Flat hydraulic cylinders feature a nitro carburizing surface treatment providing greater load and wear resistance, as well as, corrosion protection in the harshest working conditions.

The CULP-Series and CUSP-Series Ultra-Flat hydraulic cylinders can be used with Enerpac hydraulic pumps - available in over 1000 different configurations – whatever the application’s requirements for speed, control, intermittent or heavy duty.

"This speed sensor largely meets our expectations. Only the connection interface deviates from our company standard. Surely you can make an adjustment for us?" Discussions between Thomas Distel, senior industry manager at RHEINTACHO, and (potential) customers proceed like this or similarly with some regularity. What is the solution?  Simple question, simple answer: A customer-specific solution is needed! Unfortunately, however, it is also the case in everyday project work that the simple answers are rarely the best answers in the long term, taking all aspects into account.

Depending on the scope and type of customisation deemed necessary, minimum economic quantities can easily exceed the quantities required by the typical industrial RHEINTACHO clientele. Wolfgang Sexauer, Head of Sales & Marketing: "We operate in a very demanding industrial environment. Our customers mostly not need automotive or B2C-like quantities. They value the perfect balance of high quality, cost efficiency and ensuring a long product life cycle." 

What is the solution? Already in the analysis phase of a project, RHEINTACHO differentiates between application-specific requirements that are assessed as reasonable across various customers and whose individual modification would also be costly. Complex in terms of changes, geometry, electronic layout, etc. But also, with regard to qualification and validation measures. And even customer-specific characteristics. An example of this is certainly the connection interface. An intelligent design is also characterised by the fact that customised individualisations can be implemented with the least possible effort and, in the best case, remain commercially attractive even with smaller batch sizes. Solutions can only be optimal if they meet the requirements exactly. This requires good market and application knowledge, combined with the ability to listen, and engage in dialogue.

Jörn Strasser, senior industry manager, is responsible for some important partners in the measurement technology sector: "In digital hand tachometers and stroboscopes, RHEINTACHO is a real hidden champion and Europe's largest manufacturer - and we also feel very comfortable in this position."  

In contrast to sensor technology, the differentiations in the field of measurement technology are mostly marketing-driven implementations of corporate design languages and rarely functional differences.  In terms of effort, this makes no difference - quite the opposite. In the case of speed sensors, the decision for or against a customised solution is an emotionless, cost-motivated matter: customisation usually simply offers advantages that can also be evaluated. Be it through a company-wide standardisation of connectors. Or a uniform signal interface and the associated uniform controls across all products. If customisation is too costly, a compromise becomes more attractive. However, this solution is then precisely a compromise. In the case of service, this can be exactly the situation in which the service employee in the field is "surprised" by a plug. Surprised because a component that has already been installed many times does not communicate correctly with the control system as expected but must first be specially configured. Of course, these cases can be handled with good and clear documentation. Theoretically, in any case.

With this strategy, which has been pursued for decades, RHEINTACHO has earned a good name for itself. The Freiburg-based measurement technology specialist is successful on the markets with customised products in both the measurement technology and sensor technology market segments.  Wolfgang Sexauer: "We serve this demanding market niche with enthusiasm and success. And also, with the ambition to simply provide our project partners with the perfect products. It is very important for us to be technically up to date with our own products sold under the RHEINTACHO brand. We must credibly and authentically demonstrate our know-how on a daily basis. Without this solid basis, successful OEM products simply could not be marketed successfully. "

Through their cooperation, the two global market leaders ECOM and Ericsson guarantee and accelerate the transformation towards Industry 4.0.

The business case for private cellular networks in Industry 4.0

The fifth-generation of cellular technology 5G, is often touted as a key enabler for the digital transformation of industrial sectors, notably manufacturing, with specific Industry 4.0 use cases built around ubiquitous coverage of business process operations that may span across a large geographical area. In this case, the inability of public 5G or 4G LTE (an advanced form of 4G) networks to cover all the sites of large corporations is driving private cellular networks. These also allow the secure connection of remote Industrial Internet of Things (IIoT) devices and computing found at the edge (perimeter of a 5G coverage area) to central data centers.

Traditional wireless technologies, like Wi-Fi, often struggle to support business- and mission-critical applications. Businesses and their operations are demanding faster, more secure, and more reliable connectivity that can scale as you grow, while supporting innovative applications through open APIs. Ericsson Private 5G is Ericsson’s next generation private network product providing secure and reliable 4G and 5G connectivity through its single server dual mode core. Built for business operations, the product comes pre-integrated to ensure rapid time to use and turning on advanced and intelligent operations in any environment.
