A large control valve optimized for anti-surge applications
This company rounds off its proven series of Ecotrol control valves at the high end with the development of the nominal size DN 700 (28 in.). This valve has been specially optimized for use as an anti-surge valve on turbocompressors, but can also be used for all control applications involving liquid and gaseous media. The valve offers a high flow coefficient, K vs
, which usually well exceeds the delivery capacity of the turbocompressor. The quantities of gas trapped inside the pipelines and heat exchangers can therefore also be relaxed in a very short space of time upon safety shutdown of the compressor. Actuating times are short — usually considerably less than 2 s for the complete 0 to 100% valve opening. — Arca Regler GmbH, Tönisvorst, Germany
New repeater-node technology extends range, redundancy

The repeater-node system will help extend range by connecting several repeaters, enabling switching from device to device. The repeate
r-node system also provides carrier-strength redundancy through multiple networking paths. If one connection goes down, it will be instantly rerouted. — AvaLAN Wireless Systems, Inc., Madison, Ala.
A device to detect dust in wet gases
Conventional dust-measuring devices are unable to differentiate between dust particles and water droplets, resulting in incorrect measurement results. The FWE200DH provides the solution: the dust-measuring device continually extracts the waste gas from the stack, dries it with a thermocyclone, and uses forward scattering to take high-precision measurements of dust concentrations, which are usually very low. The FWE200DH can be attached directly to the stack. Since no moving p
arts come into contact with aggressive gas, the measuring device is very low-maintenance. The FWE200DH can be used for monitoring wet-scrubbing plants, taking measurements in saturated gas following fluegas desulfurization, and measuring dust concentrations in wet exhaust air.— Sick AG, Wildkirch, Germany
Extend VFD service life with these devices
This company’s Sine Wave Filter products eliminate premature motor damage from overvoltages, cable ringing, motor overheating and eddy-current losses caused by variable frequency drives (VFDs). Suitable for motor frequencies up to 600 Hz, this technology converts the rectangular pulse-width modulation (PWM) output voltage of motor drives into a smooth sine wave with a low residual ripple. In addition to elongating the service life of high-speed motors, the Sine Wave filters can improve bearing life by eliminating circulating bearing currents. Typical applications include pumps, conveyors, compressors, HVAC applications and motor drives with multiple motors or long motor cables. — Schaffner EMC Inc., Edison, N.J.

This gas analyzer detects traces of H2 in gas mixtures
The ProCeas H2
trace analyzer is said to be the world’s first device capable of measuring H2
via infrared (IR) radiation using optical resonance laser spectroscopy. The system enables direct, continuous measurements of low H2
concentrations (up to 3 parts per million) in Cl2
or other gas mixtures in realtime for control of industrial processes. The system is based on the company’s patented OFCEAS (optical feedback cavity enhanced absorption spectroscopy) technology and low-pressure sampling techniques. OFCEAS is said to be extremely precise for both simple and complex gas mixtures. The optimized optical resonance system produces a very long optical path — 10 km instead of 10 m achieved in conventional Fourier-transform IR and non-dispersive IR technologies — thus enabling sub parts-per-billion detection. — AP2E, Aix-en-Provence, France

Increasing pastillation productivity for viscous melts
Sandvik Process Systems
The new ThermoCut system is the latest addition to this company’s Rotoform technology, and was developed to increase productivity and result in a better-quality end product with high-viscosity melts. In the past, a common issue faced by processors handling advanced, high-viscosity products is the formation of threads, commonly known as “angel hair.” These threads, created when the melt is deposited on the steel-belt cooler, can result in a less-than-perfect pastille shape, as well as an increase in dust formation and increased cleaning requirements. The ThermoCut system was developed to solve this problem. The system works by blasting a narrow jet of high-pressure, heated air at the precise location where droplets are formed between the Rotoform and the steel belt. The hot air blast cuts the threads before they have a chance to develop further. This not only leads to better quality pastilles (photo), but also results in a substantial reduction in the need to clean the machine. — Sandvik Process Systems, Fellbach, Germany

This sieve mill challenges agglutinated products
The formation of agglomerates can make additional processing of materials difficult and can negatively affect the quality of the final product. The Conika sieve mill solves this problem, by preventing powders and granules from forming agglomerates during storage, and thus minimizes loss for further processing. The internal rotor of the Conika shears the material through a conical sieve. The conical shape reduces the friction in the process and thus keeps the energy input into the product to a minimum. This results in less warming of the product. All wetted parts, including the sieve, are stainless steel. — IKA Werke GmbH & Co. KG, Staufen, Germany
