Night of Radolfzell’s companies

On the 5th of May 2017 the "Night of Radolfzell’s companies" took place. Important companies in the city opened their doors to extraordinary and spectacular places that are not normally seen. Music, artistic acts and culinary highlights made the companies experience this night.

Including Allweiler.



Monitoring vibrations, mechanical seals, and bearings for safety and performance    

With more than 70 years of experience in plastics processing, Switzerland-based Quadrant Group is a leading expert in a wide range of polymer materials and technologies for polymer conversion. In order to maintain a high level of quality in the production process, Quadrant''s heat-transfer pumps must work safely and reliably. These pumps are commonly subjected to high loads. At the same time, failure of a pump can have serious consequences, especially if hot oil escapes. The high loads on the pump are the result of high temperatures and large temperature differentials as well as decomposition reactions that may occur when the heat transfer liquid is subjected to excessive thermal loads.



Pumps for synthetic heat-transfer liquids    

As soon as the temperature in a heat-transfer system becomes too high for water, a plant operator must choose between petroleum-based or synthetic oils as the heat-transfer liquid.  When modern petroleum oils are used, systems with feed temperatures up to about 300 °C can stay in service for their entire service life with one filling and with virtually no maintenance. Once feed temperatures rise above 300 °C, only high-quality synthetic oils will be appropriate. Under these conditions, even minor temperature increases will have a decisive effect on the service life of the oils. An additional 10 °C commonly doubles the product''s specific rate of decomposition. 



Pumps are the heart of heat-transfer plants   

Manufacturers in a variety of industries depend on heat-transfer plants to heat or cool their machines and apparatus. German firm heat11 GmbH & Co. KG specializes in heat-transfer plants of virtually all types. The chemical industry uses their installations for controlling the temperature of reactors and during the production of color pigments and liquid crystals. In the plastics industry, heat-transfer plants are essential for producing polyethylene terephthalate (PET) and in the production of CDs and DVDs. But recently, according to heat11’s Managing Director Dietmar Hunold, heat recovery has become an increasingly important application. 



Peristaltic pumps for moving filtration water  

The Eversburg sewage treatment plant is designed to serve 250,000 population equivalents. But in 2005, its actual load was closer to 309,000 population equivalents (COD 80 mg/l), pushing the nitrogen input level above the plant''s capabilities.

To deal with this situation, engineer Peter Sikora organized a team to develop a process-based alternative to biological elimination of nitrogen. The pumps moving filtration water into the nitrogen elimination plant are a critical aspect of the concept. In 2006, the plant began using Allweiler peristaltic pumps as an alternative to the centrifugal pumps from another manufacturer.




Temperature and leak monitoring boosts safety and reliability 

Amcor Flexibles Singen GmbH is a manufacturer of printed and unprinted aluminum-based packaging materials and an experienced technical applications specialist. High-performance drying equipment is essential for Amcor’s production process. Having centralized thermal oil pumps that operate safely and dependably is critical for the drying process.
