Safe valves for oxygen.

Valve specialist Goetze is offering its customers a unique safety valve with swivel body outlet for gaseous oxygen and oxygen mixed gases.

Safety valves specially used for applications with oxygen are needed in multiple industries. Particularly in the production of technical gases, medical gases, by compressor manufacturers as well as component manufacturers and plant manufacturers.

Oxygen handling requires extreme care as regards all materials, sealing materials and lubricants used and in contact with oxygen to prevent application risks. Goetze takes account of these requirements: By offering a production process specifically designed for oxygen valves. They are installed in a separate, isolated CLEAN room, which is pressurised with conditioned air at 20 millibar, so that the ingress of particles and contamination from the outside is avoided. Qualified and trained staff, compliance with all relevant codes and regular process monitoring of oil and grease-free cleaning, installation, inspection, packaging and labelling grant customers an oxygen-compliant valve for their applications.

Optimum material selection, the appropriate studies by the Bundesanstalt für Materialforschung (BAM, Federal Agency for Materials Research and Testing), as well as inspections by C.T.E. (Air Liquide) exclude all possibilities of an oxygen reaction (burnout). A special property of the Goetze safety valve 492GOX is that it was explicitly inspected and approved for oxygen with adiabatic pressure shocks in a range between 50 bar and 420 bar at 60 °C.

The compact design and the swivelled body outlet allowing for adjusting the valve position even after installation, make the safety valve 492GOX to an innovative gain for the Goetze product portfolio.

Fish feed producer saves power!

A specialist in aquafeed production has replaced an ageing, damaged DC motor on its principal extruder with a Dyneo® motor from Leroy-Somer, part of the Nidec group. The investment is providing the company with significant annual savings in energy costs.

Aquaculture, more commonly known as fish farming, is a rapidly growing sector. Companies such as Aller Aqua, which produces both freshwater and saltwater fish feed, is constantly looking for ways to improve its production technology and processes to benefit from this growth. Operating from headquarters at Christiansfeld, near Kolding, (DK), Aller Aqua has been established for over 50 years and today has factories in Denmark, Poland, Germany and Egypt, exporting products to more than 60 countries worldwide.

The company has a broad product range, consisting of feed for 30 species of fish. As a result, production schedules are demanding, which is why the company sought to maximise its potential gains when the DC motor on one of the company’s main extruders at Christiansfeld had to be replaced.

“Aller Aqua had a particular interest in energy efficiency for its new motor solution as extruding feed stuff is a very energy-intensive process,” explained Carl Erik Niemann, Sales Engineer - Drives & Motors Technology at Nidec Industrial Automation Denmark A/S. “They knew this would help boost both competitiveness and sustainable development.”

After a comprehensive evaluation of the market, the company opted for a 310 kW (2400 rpm) Dyneo® permanent magnet synchronous motor. Offering an efficiency level exceeding IE4 requirements, this option will enable the saving of at least 135,000 kWh of electricity per year.

“Beyond energy performance, Aller Aqua is now able to benefit from significant savings in maintenance costs, allied to increased machine availability,” said Mr Niemann. “The previous DC motor featured a brush and collector system, which comprised wear parts.”

The implementation of the Dyneo® motor also allowed local service centre Ølgod Elektro to simplify the existing installation by eliminating the cooling/ventilation circuit required previously by the replaced IP23 DC motor.

Optical sensors up-to-speed.

Oxford Brookes Formula Student team used a Correvit® S-Motion 2 Axis Optical Sensor from Kistler Instruments to obtain the key data needed for accurate, real world tyre modelling.
The Oxford Brookes University, 5 times winner of the British Formula Student competition, decided that better tyre modelling was essential for their 2018 campaign than that provided by data from a sandpaper belt test rig courtesy of the Formula SAE Tire Test Consortium. The team decided that real world data would be needed to support future development of the Oxford Brookes Formula Student car. Tyre slip angle, the key data needed for accurate tyre modelling, was obtained using a Correvit® S-Motion 2 Axis Optical Sensor on loan from Kistler Instruments.

As tyre modelling lead, Brad Mallinson, explains, “While vertical load, inclination angle, ride heights, and vehicle roll angle are relatively easily measured, tyre slip angle is very difficult but critical to the development of an accurate tyre model. Kistler’s S-Motion sensor accurately measures vehicle longitudinal and transverse speed and slip angle with a high logging rate which is essential for the relatively low-speed Formula Student driving events.”

The S-Motion unit was mounted on the 2017 Oxford Brookes Formula Student car, along with load cells, infrared tyre temperature and laser ride height sensors to collect as much tyre data as possible. A major benefit of the S-Motion system is the time saving “Plug & Play” capability which drastically reduces vehicle preparation time; essential to take full advantage of the short time frame for tyre testing after the Formula Student season. A further advantage of the Correvit® system is the ability to automatically transform speed and slip angle measurements to any point of interest on the vehicle. These were transformed to the centre of gravity where yaw rate was measured, simplifying tyre slip angle calculation during steady-state tests.

Testing consisted of increasing velocity runs on a constant radius skid pad for a minimum of three cold inflation pressures and three static camber settings to capture the quadratic relationships in the lateral force model. Quantities derived from measurements were calculated in MATLAB before being passed to the tyre model tool. Roll angle measurements from the S-Motion and damper displacement data were used for lateral weight transfer models to determine inclination angle and total vertical load. Steered angle of each front wheel was used to calculate front tyre slip angles using vehicle slip angle from the S-Motion.

Like the Oxford Brookes Formula Student Team, many automotive manufacturers are now using the Correvit® S-Motion and other sensors by Kistler to generate data for tyre models that represent real world tyre performance.

Dissolved Oxygen in food, pharmaceutical and biotechnology.

The sensor accurately measures oxygen and temperature in demanding fermenter, bioreactor, water treatment and boiler feedwater applications.

The Memosens COS81D hygienic optical sensor for measuring dissolved oxygen in fermenters and bioreactors has been released by Endress+Hauser. It is for use in the food, pharmaceutical and biotechnology industries, as well in drinking water and boiler feedwater applications. It can be used in all measuring points from lab fermenters to production processes.
The Memosens COS81D measures dissolved oxygen, gaseous oxygen and temperature with accuracy up to ±0.2%. It works in process temperatures from 15 to 280 °F and pressures from 0 to190 psi. The sensor also provides temperature and partial pressure, as well as raw measured values. The sensor connects to a transmitter via a cable that transmits an optical digital signal.
The sensor accurately measures oxygen and temperature in demanding fermenter, bioreactor, water treatment and boiler feedwater applications.
The sensor withstands CIP and SIP procedures, and resists halogen-containing solvents, ketones and toluene. The sensor is a compact stainless steel 12mm design with lengths currently up to 220 mm. The sensor has a low sampling volume, making it well suited for residual oxygen measurement in water treatment and boiler feedwater.

The stainless steel sensor meets EHEDG (type EL class I) and ASME BPE (including USP class VI and FDA conformity) hygienic requirements to avoid product contamination, and meets the requirements of GMP and GLP. It also has a Certificate of Compliance for biological reactivity tests as per USP (United States Pharmacopeia) part 87 and part 88 class VI, with batch traceability of materials in contact with product.

Two spot cap versions are available with the sensor: a C-shaped cap and a U-shaped cap. The first is particularly well suited to measurements in liquids, specifically in fermenters and bioreactors. The distinctive design of the U-shaped cap protects the spot from abrasion that can occur, for example, in gas measurements. The caps, specially designed for hygienic applications, reduce blockages and the adherence of air bubbles. Thanks to these caps, the sensor delivers extremely stable measured values across the entire measuring range. This stability is maintained even after dozens of CIP and SIP cycles.

The sensor can be replaced within seconds. The user simply calibrates the sensor in the lab, and then inserts it into the sensor holder assembly. It does not require any polarization time and is immediately ready to measure. The sensor has integrated electronics that store calibration data and other information, such as total hours of operation and operating hours under extreme measuring conditions. Once the sensor has been connected, the sensor data is transferred automatically to the transmitter and used to calculate the current measured value. Because calibration data is stored in the sensor, the sensor can be calibrated and adjusted independent of the measuring point.

Measured and calibration values in the sensor are sent to the transmitter using a non-contact connection that is free from potential interference. Memosens technology in the transmitter generates an automatic error message if the sensor fails, or if the connection between sensor and transmitter is interrupted.

The optical signals are continuously monitored and analyzed. The transmitter detects implausibly high or low measured values, irregular values due to incorrect measured values, and aging of the sensor cap. When errors are detected, the transmitter displays a warning and generates an error message.

Air quality training!

Reflecting the level of support and expertise that Ashtead Technology has been able to provide for its sales and rental customers over the last year, TSI has renewed Ashtead’s Gold Partnership status. The achievement of this level of support triggers higher levels of engagement with TSI, resulting for example, in joint activities such as free air quality training events.
One such event took place in January, focusing on both indoor and outdoor air quality. “Previous training days have taken place at TSI’s headquarters in High Wycombe, but this year, to give our customers in the north of the UK the same opportunity, we moved it to the Magna Science Adventure Centre in Rotherham,” explained James Carlyle, Ashtead Technology General Manager. “We were delighted with the level of enthusiasm for the day, and feedback from delegates was extremely positive,” he added.

Two of the attendees from WSP, a 7,640 strong British engineering consultancy, travelled to the Magna Centre from their Cardiff office. Luc Porter, a Principal air quality consultant at WSP, said: “It was great to gain some practical hands-on experience with a variety of technologies, and to see the latest TSI models. We also found it useful to engage with the other delegates; sharing knowledge and experience.”

The day began with a presentation by Ashtead’s Josh Thomas, who outlined the reasons for monitoring particulates; including the management of indoor air quality and regulatory compliance. He explained which instruments are most appropriate for specific applications, citing examples in applications such as cooking, soldering, construction, manufacturing, animal husbandry and even smoke management during the filming of feature films.

The next speaker was Nicholas Baxter from the Health & Safety Laboratory (HSL), which is the science division of the Health & Safety Executive. He described the requirements for Respiratory Protective Equipment (RPE), including an explanation of the terms ‘adequate’ and ‘suitable’ with respect to RPE. He also highlighted the importance of the CE mark, correct storage of RPE, and Fit Testing, as well as employer and employee responsibilities. This was followed by a practical demonstration of FFRED (HSL's Face-Fit Respirator Demonstrator) which highlighted the problems caused by badly fitted masks.

Technical presentations were also provided by TSI – Maxine Dolloway described the DUSTTRAK and SIDEPAK range of particulate monitors, and Nick Brown outlined the advantages of the Environmental DUSTTRAK. The participants were given numerous opportunities throughout the day to work with all of these instruments.

Appointment in Food & Drink ops.

Todd Gilliam has been appointed to the position of US segment leader for ABB’s food and beverage operations. He succeeds Cliff Cole, who has taken on the role of leader of commercial and strategic integration after three years in the position.

Todd Gilliam
Gilliam joins ABB from Schneider Electric, where he was a food and beverage industry manager since September 2014. He has over 30 years of experience in manufacturing, having been a global account manager for brands such as Coca-Cola and Microsoft.

In his new role at ABB, Gilliam will lead a team that represents all of ABB’s current business units. The team will take responsibility for educating and informing food manufacturers on the impact digitalization is having on the industry and what long-term solutions are available to improve efficiency and profitability.

“Digitalization has been at the forefront of manufacturers’ minds for a number of years now, and many are inter-ested not only in optimizing existing assets to keep up with their competitors, but also leveraging new technologies to gain a strategic advantage,” said Gilliam. “As an industry, food and beverage has traditionally been a slower adopter of new technologies when compared with sectors such as energy or processing. Rather than playing catch up, manufacturers are now looking at what the future holds and how they can make their own facilities smarter.

“At ABB, our aim is to assist manufacturers in futureproofing their operations. For the vast majority, building a new facility isn’t an option. Industry 4.0 has led to the creation of a wealth of technologies that can enhance existing operations, improve efficiencies and minimize production downtime.

“Big data, a phrase that is commonly thrown around, will play a big part in this. In the industrial context, many manufacturers collate data from disparate sources, but few are able to truly understand it and use as actionable operational information. We want to change this.”

“Todd brings a wealth of experience to the role that will be invaluable to ABB,” added Markus Brettschneider, senior vice president and general manager of ABB’s global food and beverage applications. “His ability to develop rela-tionships and look at the bigger picture for clients will be important to the development of ABB’s work in the US food and beverage industry. We’re delighted to have him on board and look forward to seeing the changes that he will bring.”

Gilliam will be based at ABB’s Atlanta office in the United States. He holds a Bachelor’s Degree in electrical and computer engineering from the University of South Carolina.
