TECHNOLOGYIN ACTION Pfeiffer Vacuum introduces new HiScroll ATEX scroll pump
The new pumps in the HiScroll ATEX range meet the requirements of the Eu- ropean directive 2014/34/EU and are marked according to ATEX II 3/-G Ex h IIC T4 Gc X +5° C ≤ Ta ≤ +40 °C. This identifies the HiScroll ATEX as suitable for pumping potentially explosive gas mixtures. Depending on the operational requirements, the ATEX directives are subdivided into different categories based on the conditions under which the pumps are allowed to operate. The HiScroll ATEX conforms to equipment category 3G based on contact with the pumped substance and meets temperature class T4. This allows all gases up to and including explosion group IIC to be pumped. It is even possible to pump hydrogen.
With these properties, the HiScroll ATEX covers many applications in the field of analytics, industry or research & development. Explosion-protected devices are used in many sectors, including in industrial processes such as generating and pumping hydrogen. The HiScroll ATEX is also used in labora- tories for pumping solvent-based liquids and gases which can produce combustible vapors. The ATEX certification is awarded since the HiScroll ATEX has no sources of ignition for potentially hazardous gas mixtures. Pfeiffer Vacuum scroll pumps offer high pumping speeds during pump- down, even at atmospheric pressure. The completely dry and hermetically sealed vacuum pumps achieve a nominal pumping speed of 6 to 20 m³/h. They are characterized by their compact design and extremely quiet, low- vibration operation (<47 dB[A], in stand-by mode <42 dB[A]). They have a high water vapor tolerance, and condensation in the vacuum pump is therefore prevented from the start. The integrated two-stage gas ballast valve allows individual adjustments to be made to the process require- ments.
The pumps can be easily connected to other Pfeiffer Vacuum products, such as turbopumps, via RS-485, EtherCat or ProfiNet and can be operated with a higher-level controller or a PC. The intelligent interface enables use of the RPM regulator or the innovative stand-by mode, which allows the pump to be optimally adjusted and operated for the application. At the same time, this minimizes pump wear and extends maintenance intervals. The proven Pfeiffer Vacuum quality due to high-quality, durable compo- nents ensures a long lifetime, low operating costs and reduced environ-
mental impact. Easy maintenance of the pumps enables not only shorter service times but also maximum availability. The integrated safety valve and self-regulating operation of the pump guarantee its safe operation. The powerful yet efficient drive is characterized by a 15 % higher effi- ciency compared to conventional drives. This enables maximum perform- ance at low temperatures and easier and more cost-effective cooling.

Rheonik Hydrogen Coriolis – Leading The Field In H2 Mass Flow Measurement
Hydrogen fuelled vehi- cles have become a common sight in areas where investment has been made in the “hy- drogen highway” to es- tablish filling stations and fuel supply to support such vehicles on the road. America, Canada, Japan, China and many European countries have already invested large sums of money to estab- lish a basic network of hydrogen stations sup- porting fuel cell cars. With many fuel cell ve- hicles from several man- ufacturers already on the road and with many
more to come, the hydrogen highway will continue to be expanded to pro- vide the capacity needed to keep them running. Rheonik is a pioneer in the hydrogen fuel cell revolution. From the very outset, Rheonik has worked with all the major hydrogen suppliers to produce flow meters that are both ac- curate and can handle the extremely high pressures associated with hy- drogen distribution and dispensing.
This is underlined by Rheonik being the first Coriolis manufacturer to ob- tain a custody transfer approval for a broad range of mass flowmeters for mobile and stationary hydrogen applications up to 1070 bar according to MID MI002 / OIML R137. Rheonik has also gained Certificate No TC11811 for the fiscal harmonised standard OIML R139, for equipment used to deliver com- pressed gases (natural gas, hydrogen, biogas, etc.) in dispenser systems up to 700bar.
The implementation of clean fuel technology such as that found in hy- drogen fuel cell vehicles is an increasing priority for many countries as con- cerns about global warming and its effect on the planet continue. Rheonik are proud of their contribution to the industry and will continue a pro- gramme of improvement to provide even better solutions and perform- ance to support these important global warming reduction initiatives. Hydrogen is transferred to storage and into fuel cell vehicles at very high pressures, high velocities and at varying temperatures. The provision of a flow meter to measure under these conditions is not a trivial matter as it must be accurate, reliable and suitable for end user point-of-sale billing. Rheonik mass flow meters have proven to be, and continue to be, the most reliable meters for H2 measurement available. Consequently, Rheonik’s Model RHM04 was supplied and is currently the only mass flow meter that can meet the necessary criteria.
Going forward Rheonik and ABLE Instruments will continue developing hy- drogen solutions that will support a more sustainable world through cleaner processes and effortless refuelling. These new systems will bring flexible, affordable opportunities to the growing hydrogen market.
