Everything about liquids and gasses handling

Crusta is a company in the Dutch village Urk. The company is specialized in live shellfish, such as King Crabs, Canadian Lobsters, North Sea crab and Oysters. To keep the animals in optimal conditions, Crusta created the perfect environment: The Crusta Ocean. This is a state-of-the-art salt water auto-refreshing system with a capacity of 500.000 litres, which closely recreates the natural living conditions of the shellfish. That's were Polem was able to help Crusta: we supplied them two isolated 35m3 tanks, with a diameter of 2,80 m to store fresh seawater. This helps them to keep the Crusta Ocean in perfect condition. The salt seawater will not harm the storagetank, because composite is not sensitive to corrosion. After installation of the tanks, the customer replied to us: "The tanks are beautifull and with compliments to the truck driver for his carefull delivery!"

What is electrical Heat Tracing? Wherever freeze protection or temperature maintenance is needed, electrical heat tracing can be used. It is operated with electricity and the heat is generated by the conversion. There is a wide range of applications of trace heating, most common in industrial and public areas. Electrical heat tracing on: - Pipelines - Tanks and vessels - Silos - Tank containers - Pumps - Valves - Open areas Such heating ensures process-safe transport, appropriate storage or processing of e.g. various foodstuffs, greases, oils, adhesives, but also paints, lubricants or quite simply water. There is a wide range of specific applications.

Pumping cryogenic gases is no easy task. To liquefy this type of substance, the temperature must be lowered, and the system pressure increased. Cryogenic liquids are therefore different from "normal" liquids. Because they are processed at an extremely high system pressure, from 50 to 200 bar or more, and an extremely low temperature up to –200 °C. The viscosity is also extremely low (> 0.1 mPas); about a tenth of water. It is mainly the combination of these physical properties that makes it difficult. For the pulsation-free pumping of cryogenic gases, depending on the desired differential pressure, both gear and turbine pumps are the perfect solution for these challenging applications. The (shaft) sealing of the pump requires special attention. This is very difficult due to the extreme system pressure and temperature. A normal shaft seal (such as a gasket, lip seal, mechanical seal, etc.) is virtually impossible because it is blown out of the pump by the extreme pressure difference inside and outside the pump. Magnetically coupled pumps The pumps we offer for this application are equipped with a magnetic coupling with seals that are suitable for system pressures up to 325 barg and extremely low temperatures up to –200 °C. Due to the application of a magnetic coupling, there is no shaft seal, only static seals. As a result, the pump is hermetically closed and there is no risk of jams due to ice deposits. The materials of the seals must be especially resistant to extremely low temperatures, such as PTFE (= TEFLON®), FFPM (= Kalrez®) or metal (e.g. silver). In order for the process to run smoothly, the pump and the pipes must be insulated to prevent ice build-up by moisture from outside. SUURMOND offers three types of pumps that have been used for cryogenic applications. Two types of gear pumps and a turbine pump. The choice is determined by, among other things, the desired differential pressure, the required system pressure, and liquid temperature. Examples of cryogen applications: - Pumping of liquid nitrous oxide (N2O) as refrigerant - Pumping of liquid carbon dioxide (CO2) as a refrigerant - Pumping thermostatic fluids; ethylene glycol, silicone oils, etc. What kind of demanding applications do you have? Let's talk!

New sliding gate control valve type 8621, designed in accordance with ASME standards With the new type 8621, Schubert & Salzer combines ASME standards for the first time with sliding gate technology. It is the first sliding gate control valve not to be built in wafer design, but instead on the basis of ASME B16.34, including a flange connection according to ASME B16.5. Sliding gate valves can now be selected with a standardized overall length according to ANSI ISA 75.08.01; plant operators can quickly and simply replace traditional globe valves by much more efficient valves with sliding gate technology. In comparison with globe valves, users of sliding gate valves benefit from critical advantages, such as minimal consumption of energy due to small actuation forces and fast response due to small strokes. Other features are the controllability of high differential pressures with small actuators, low-noise, and cavitation-insensitive operation as well as high variable Kvs values. The new sliding gate control valve type 8621 is the first Schubert & Salzer valve to be produced not only in Germany, but also in the USA at our location in Concord, North Carolina.

Read how Woodlands Dairy optimized food safety, workplace safety and efficiency with reliable and fully compliant labels and pipe markers from Brady. Woodlands Dairy is one of the largest manufacturers of UHT milk in South Africa, marketed under their brand First Choice. The company also produces various cheeses, butter, cream, amasi, custard, flavoured milk, dairy desserts, dessert toppings and ice cream. Woodlands Dairy needed a quality pipe marking and identification solution that does not fade when exposed to heat, cold, and liquids. Above all, the solution should be free of any toxins and fully comply with food safety legislation. Solutions: Compliant pipe markers and signs that stay attached and remain legible Brady visited Woodlands Dairy several times to meet with senior management on how identification solutions could optimize food safety, workplace safety and operational efficiency. Pipe marking appeared essential for workplace safety because it can quickly unveil any risks associated with a pipe’s hidden contents. Brady proposed its custom-developed pipe-marking materials for food & beverage industries that comply with hygiene and safety requirements in food safety legislation. They are made out of non-toxic materials that stay firmly attached to pipes that are exposed to heat, cold, and liquids. Their print and colour code immediately informs employees where it matters about potential risks, urges them to wear the proper protection, and to take relevant precautions before opening a valve for example. A section of the site was being updated and Woodlands Dairy decided to immediately implement floor marking. Floor marking helps create a highly visual workplace that offers increased efficiency and safety. Brady offered its highly reliable ToughStripe Floor Marking Tape. The tape can resist heavy foot and light vehicle traffic, does not need time to dry, and, unlike paint, does not release any chemicals or fumes that could threaten food production. Woodlands Dairy also uses compact, hand-held BMP21-PLUS Label Printers from Brady to support ongoing safety and efficiency identification in the facility. The BMP21-PLUS is ideal for cable & component identification, including switches and fuses in electrical panels. A clear, reliable label quickly shows which circuit each fuse controls, and it leaves little room for error. Brady selected B-595 vinyl labels together with Woodlands Dairy. B-595 is a great all-round identification label with good adhesion to steel, powder-coated metal, textured surfaces, polypropylene and glass. Exposed cables are identified with stainless steel tags and cable ties for ultra longevity and additional food safety. Stainless steel tags that would get into any food supply are easily picked up by metal detectors. Results: Optimised food safety, workplace safety, and efficiency Woodlands Dairy has optimized food safety, workplace safety and efficiency by sharing vital information where it matters with clear and reliable signs, labels and pipe markers. “This is a really good product”, said Theo Oosthuizen, senior technician at Woodlands Dairy. “We have used other pipe markings in the past, but inevitably they faded. I would definitely recommend using Brady products again in the future.”
