Rietschle Thomas will hold a forum on the ATEX directives on its stand at this years Total exhibition.
In view of the confusion following the introduction of the ATEX directives, vacuum pump and compressor manufacturer Rietschle Thomas is holding a forum on Stand 1H11 at this years Total exhibition.
Process Systems Manager Dave Laurenson will be on hand to discuss the implications of the ATEX directives for plant and project engineers.
He can also offer advice on complying with current and future ATEX legislation, including pump selection and system design related to various process and industrial applications.
ATEX-certified vacuum pumps and compressors on display will include the vertically mounted, rotary vane VLV series, and the Zephyr VLR twin claw rotary lobe designs.
However the central feature of the stand is the cool-running Twister series, which complies with Category 1 of the ATEX Equipment Directive 94/9/EC.
Thought to be one of the simplest screw vacuum pump designs on the market, the Twister has now passed the necessary inspections and tests for use in potentially explosive atmospheres; in Zone 0 T4 gas group IIb areas (internal hazard zone rating), and in Zone I T4 gas group IIb areas (external hazard zone).
The low temperature performance of the pump is the result of a patented, progressive pitch screw with internal compression rather than complex computer control of the drives, or cooling of the screws.
This highly efficient design also offers up to 30% savings on power consumption, compared with standard screw sets.
