Current-limiting devices:Strengthening the weakest SCCR link
Research indicates that more than half of OEMs design their machines to a typical minimum equipment SCCR of 5kA. However, with the new NEC code, valid after January 2017, it is possible that many equipment installations will not be code compliant or approved. Suppliers such as Eaton, with major operating footprints in North American and IEC markets, are fully aware of global regulation updates.
This white paper explores the standards and best practices for determining equipment SCCR and the approved methods to increase ratings. With an appreciation of best practices, OEMs can build equipment with enhanced safety and reliability, designed for a larger range of available fault currents, and this in turn ensures they can better support their end user customers.
Power Xpert Release (PXR) platformEaton’s Next Generation Trip Unit Makes It Easy to Test Circuit Breakers
Eaton has launched its next generation trip unit for the global market – the Power Xpert Release (PXR) platform – which enables engineers to test and configure circuit breakers from a PC via a USB port. It is integrated into the power management company’s IZMX air circuit breakers. As a result, it is easier for users to interact with the trip unit and store test data, thereby improving control and maintenance regimes.
High current circuit breakers – for example those used in high power distribution systems in industry – are configured and periodically tested by end users to ensure they continue to work reliably in the case of over-currents, and therefore prevent expensive downtime. This new unit allows technicians to simulate short circuits and overloads using Eaton’s Power Xpert Protection Manager (PXPM) software tool, which can be downloaded at no charge.
“The unit has been developed in response to user demand for an easy-to-use system. Previously test data
EHEDG magnetic filter with CIP cleaningMagnetic filter meets the highest food safety standard
The EHEDG magnetic filter recently introduced by Goudsmit Magnetics is specially designed for the food industry. This hygienic filter is suitable for CIP systems: the magnet can be magnetically operated, without the need to open the filter housing for cleaning. The filter is constructed of Neodymium magnets that provide more effective separation of very small ferrous particles as small as 15µm, weakly magnetic particles and even iron dust from sticky substances such as chocolate, pastes, powders and fruit juices. The magnet has a maximum flux density of 11,300 gauss at the bar and removes the specified particles from both liquid and powdered products. The entire system is made of grade 316 stainless steel, is smoothly finished (Ra≤0.4ųm) and is EHEDG certified.
Cleaning of the magnet occurs automatically. When production is stopped the magnet can be ’blown’ out of the product flow so the flushing cycle can carry away the captured ferritic
Flex Tube Diverter Reduces Cross Contamination for RecipesVortex Flex Tube Diverter Valve Handling Chili Powder
When this national company was considering a new blending and mixing station, much of the emphasis for the project was placed on increasing output with additional production efficiency.
Previously, the company had experienced issues with valves and diverters within an old system. The diverters caused cross-contamination among the product recipes and the slide gates leaked to atmosphere. In both cases, the expensive chili powder had to be trashed. Chili powder leaking to atmosphere creates an airborne health hazard (eyes and skin) and also a “slippery floor” safety hazard for company employees.
The new system incorporated a Vortex flex tube diverter to eliminate product cross-contamination and Vortex roller gates to shut off and seal material at the bottom of dry blenders and mixers.
Production was impressed with the performance of the Vortex valves as well as the maintenance friendly features each one has to offer. “These valves truly seal our material.”
Engineering to maximise performance
With testing facilities world-wide Gericke has the opportunity to begin the engineering phase by conducting a wide variety of in depth analytical tests. This helps in identifying the customer’s product characteristics to eliminate any risks, create solutions and supply the customer with the required equipment for the factories optimal performance.
One of our specific tests that we conduct is on powder degradation, which determines the necessary conditions of the installation to minimise product damage. We analyse this by measuring product size and characteristics at the beginning of testing, transporting the powder (to replicate the intended process) and then concluding with replicating the beginning tests to analyse the differences.
3D Modeling is also an important phase to enable us to maximise the performance of our installations. Our experienced engineers begin by building the complete offered installation within a 3D model replica of the customer’s environment,
Durably identify pipes in any facility anywhere
Finding the best pipe marker material for your sites all over the world can be a time consuming task. Brady offers Indoor, Outdoor and Outdoor+ pipe markers in any colour standard that can identify pipes in any factory anywhere in the world.
Reduce accidents, increase efficiency
Clearly visible and legible pipe markers that indicate pipe contents and flow direction can increase efficiency for maintenance crews in finding the pipes that need servicing and the valves they need to shut down. Next to increasing efficiency, pipe markers help to avoid accidents by warning employees, contractors and first responders for dangerous pipe contents.
Durably identify pipes anywhere
Pipe markers reduce workplace accidents and increase efficiency as long as they stay attached and remain legible. Based on testing in our in-house laboratories, using standardised test methods, we offer Indoor, Outdoor and Outdoor+ pipe markers for maximum durability and reliability in any context:
Smartflex ductinghose suitable for EX zones
Smartflex is a clear transparent polyurethane ductinghose especially suitable for wood and pellets processing industry, where flame retardent and anti-static hoses are required more and more. The Smartflex is the solution for this application and moreover, it is hydrolysis and microbe resistant and therefor can be used in moist or wet surroundings.
The special mixture of raw materials makes the Smartflex permanently anti-static, and it meets the requiremenst of ATEX 2014/34/EC (spiral must be earthed). Therefor the hose can be used in ATEX zones where it prevents the risk of ignition due to electrostatic discharge.

The Smartflex is not suitable for foodstuff.
Gericke celebrates 120 year anniversaryOver 120 years of Industry Knowledge
Dating back to the summer of 1894 is when the family run company Gericke was first set up.
At that time, flour milling was among the first industries to incorporate automatic handling systems for bulk solids. Operations such as cleaning, conveying, storing, discharging, feeding, grinding, mixing, separating, de-dusting and bagging were already being developed.
With the emerging influence of the third Gericke family, the company established a strong development of philosophy for expansion and growth. Now over 120 years on the company is still going strong under the 4th generation management of Mr Markus Gericke.
Gericke started with just one location in the industrial district of Zurich and has now expanded world-wide by establishing subsidiaries in key countries which currently employs over 260 committed employees.
People are the company’s greatest asset and hold a key position in all future development plans. With the delegation of responsibility and
Concetti introduces MAP bagging equipmentThe shelf life of animal feed and pet food can be significantly extended
Concetti, Bastia Umbra, Italy, has introduced Modified Atmosphere Packaging (MAP), to their fully automatic bagging systems, but in an interesting and innovative way. This is designed to help dry pet food and animal feed producers offer the best quality of product and improve profitability. This technology dramatically extends the shelf life of animal feed and pet food, and preserves taste and freshness in each bag.
The Concetti company, a manufacturer of high quality packaging machinery, has just tested a fully automatic “IGF 1200” with a double feeding system, designed for gusseted open mouth paper bags with inner PE liner, from 4 to 20 kg.
The MAP application designed by Concetti consists of the replacement of air with a single gas, like nitrogen or a mixture of gases, during the entire filling process, not only in the package itself. Then, while still under a blanket of nitrogen, a device closes and seals the bags tightly. By replacing the breathable atmosphere

Vortex Slide Gate Engineered for Aqua FeedConveying a fragile product in a lean/dilute phase
Pneumatically conveying open water fish feed is never an easy task. Product breakage must remain minimal to ensure the feed floats or sinks at specific rates. There is also an added complexity of highly variable fatty oil content, ingredients, and bulk density amongst the different blends.
In 2008, Vortex collaborated with an international aqua feed manufacturer to develop a slide gate that would deliver fish feed pellets directly into a lean/dilute phase pneumatic conveying line. The success of the original slide gate design led to further cooperation on an additional aqua feed project in 2012. Many of the design parameters were similar to the previous installation, but with more specific considerations:
* Minimize material breakage by eliminating ledges through the inlet,
* Seal the pneumatic conveying pressure in the lines below the valve to prevent a pressure drop in the system,
* Handle the wide range of product variation,
