<\/a>Diamond Light Source is a particle accel\u00ader\u00adator based in Oxford\u00adshire, England. The synchro\u00adtron accel\u00ader\u00adates elec\u00adtrons to speeds approaching the speed of light, creating extremely bright light beams that can be up to 10 billion times brighter than sunlight. Researchers use this like an extremely fine micro\u00adscope. To generate the light, an elec\u00adtron gun first fires elec\u00adtrons out into an accel\u00ader\u00adator, where the parti\u00adcles are heavily accel\u00ader\u00adated. As soon as they reach the required speed, the elec\u00adtrons are shot out into the 560 metre storage ring. As the light hurtles through the ring, magnets agitate the beam, further increasing the bright\u00adness of the light. A range of labo\u00adra\u00adto\u00adries connected to the ring divert the light from the storage ring to use it for various exper\u00adi\u00adments. Over 500 staff, together with 3,000 visiting scien\u00adtists every year, conduct research into areas such as medi\u00adcine, nanotech\u00adnology, archae\u00adology, engi\u00adneering and envi\u00adron\u00admental science.<\/p>\n<\/div><\/div>\nGreat poten\u00adtial<\/h2>\n![\"magnets_diamond_light_source\"](\"https:\/\/ebmpapst-7237.kxcdn.com\/de\/files\/2014\/09\/magnets_diamond_light_source-300x199.jpg\" "\\"Foto")
<\/a>The light beam is directed through the particle accel\u00ader\u00adator by magnets. The elec\u00adtronics control\u00adling these magnets are cooled by CRAC units using EC fans from ebm-papst<\/p><\/div><\/div>\n
The pair met with James Cooper, Product Manager at ebm-papst UK, at the high-tech research facility to pin down how much poten\u00adtial existed. They exam\u00adined 27 CRAC (computer room air-condi\u00adtioning) units installed by Stulz. Instead of a server room, they cool the elec\u00adtronics used to control the magnets that convey the light beam through the storage ring. The units were previ\u00adously all fitted with belt-driven AC fans. Together with his part\u00adners, James Cooper came to the conclu\u00adsion that switching to RadiCal\u00ae EC fans would be worth\u00adwhile. \u201cWe esti\u00admated poten\u00adtial for savings of around 39 percent,\u201d says Cooper, \u201cto fully convince the customer, however, we were initially commis\u00adsioned to upgrade a single CRAC unit in a test run.\u201d This task was carried out by ebm-papst together with the installer Cinque Energy Solu\u00adtions.<\/p>\n

<\/a>Success against the clock: James Cooper from ebm-papst, David Japp from Cinque Energy Solu\u00adtions, Phil Taylor from Stulz and Lee Walters from Diamond Light Source<\/p><\/div><\/div>\n
The main chal\u00adlenge here was the small instal\u00adla\u00adtion space in the CRAC units. \u201cThese sit on a solid concrete base, so it was impos\u00adsible to assemble the EC fans in the base as usual,\u201d explains Phil Taylor. Working together with the installer, ebm-papst devel\u00adoped a special metal frame that allowed the fans to be installed in the units, despite the tight area. In addi\u00adtion, the housing posi\u00adtions the fans at the right angle to ensure the best air flow through the cooling unit. ebm-papst UK manu\u00adfac\u00adtured the special housing at its own produc\u00adtion facility to allow the customised solu\u00adtion to be imple\u00admented quickly.<\/p>\n
Green light for upgrade<\/h2>\n
The test run began as soon as the tech\u00adni\u00adcians from the installer completed the upgrade of the first unit, with posi\u00adtive results. The energy saving exceeded esti\u00admates by almost five percent. One of the most impor\u00adtant things for the oper\u00ada\u00adtors of Diamond Light Source here was keeping the temper\u00ada\u00adture constant in the tech\u00adnical space to be cooled. In order to ensure this, the EC fans are fitted with a 0-10 V controller that is easy to operate. This allows all units to be adjusted indi\u00advid\u00adu\u00adally to the require\u00adments of the spaces. The test run also revealed further poten\u00adtial for improve\u00adments: \u201cWe were able to further opti\u00admise the air flow by enlarging the hole in the housing beneath the fans,\u201d recalls Cooper. The test run and the extra effi\u00adciency improve\u00adments were enough to convince the deci\u00adsion-makers at Diamond Light Source to give the green light.<\/p>\n
A race against time<\/h2>\n![\"Fan_upgrade_ebm-papst\"](\"https:\/\/ebmpapst-7237.kxcdn.com\/de\/files\/2014\/09\/Fan_upgrade_ebm-papst-300x199.jpg\" "\\"Foto")
<\/a>The tech\u00adni\u00adcians completed the upgrade to EC fans in just two weeks<\/p><\/div><\/div>\n
The upgrade team were now faced with a daunting schedule. The fans could only be replaced during the synchrotron\u2019s brief off-line period, giving the team from the installer just 14 days to retrofit the remaining 26 cooling units. The tech\u00adni\u00adcians there\u00adfore worked in two teams of three on the upgrade. To minimise delays, ebm-papst deliv\u00adered all 54 EC fans directly to the CRAC units. The first task was to remove the old belt-driven AC motors. The installers then open-up the base plate using a special cutting tool to improve the air flow, before fitting the indi\u00advid\u00adu\u00adally adapted RadiCal\u00ae centrifugal fans from ebm-papst. After restoring all the connec\u00adtions and adjusting the manual speed controller, the system upgrade was complete. Working along this proce\u00addure, the tech\u00adni\u00adcians went from one unit to the next so that all CRAC units were fully func\u00adtional when the system was started again.<\/p>\n
