Heat is needed for production almost everywhere, in every industry.
Temperatures often rise as high as 400oC or higher. Many production processes are not viable without heat transfer fluids, which allow the heat to be passed on to the next station and not be lost. As a result, many production plants depend on organic heat transfer fluids, such as Diphyl by LANXESS.
Exact and constant temperatures are important
Organic heat transfer fluids are certainly a good idea when things are heating up, but also at lower operating temperatures. They can be divided into two categories: mineral oil-based and synthetic. At high temperatures, in particular, synthetic organic heat transfer media are the best solution.
They are used wherever precise temperature control is important. This applies, for example, to the manufacture and processing of plastics, synthetic fibers and rubber, and to the wood and metal processing industry. Heat transfer media are indispensable when the task is to make PET out of polyester, for example, and to further process it into fibers and bottles.

Sizing and Selecting the proper Metering Pump
In process application, large amounts of chemicals are used during daily operations and the volumes of chemicals are large and very precise, with exact amounts delivered according to strict injection schedules. Thus the pressures - from very high to very low – for injecting the chemicals should be governed precisely. Metering pumps have—whether mechanically, hydraulically or electronically actuated—raised to the fore as a technology of first choice for the injection of chemicals in processing and agricultural applications, but within the realm of metering pumps there are many different styles and modes of operation. The article explains the different metering-pump technologies and illustrates how the user should select the proper size and style depending on the injection application for which the pump will be tasked.

ABB to Invest 100 Million in Global Innovation & Training Campus
ABB makes largest organic investment in industrial automation at home of B&R in Austria One year after announcing its acquisition of B&R (Bernecker + Rainer Industrie-Elektronik GmbH), ABB is to invest €100 million in Austria to build a state-of-the-art innovation and training campus at the home of B&R in Eggelsberg, Upper Austria. It is the largest organic investment in industrial automation in ABB’s more than 130-year history and lays the foundation for around 1,000 new high-tech jobs in Austria.
Secure & Seamless Communication With Powerlink & OPC UA
An OPC UA companion specification is now available for POWERLINK according to a joint announcement by the OPC Foundation and the Ethernet POWERLINK Standardization Group (EPSG). The companion specification describes how payload data is exchanged between POWERLINK and any OPC UA platform. The result is integrated communication from the sensor to the cloud – without any interfaces whatsoever.​​​​​​​
