Grydale is a global leader in dust control solutions, operating in multiple countries.
Grydale hold international patients for manufacturing the only self-propelled, track mounted, mobile dust collector on the market. The mobile dust collectors boast world class operating efficiency, along with regulated air volume using a variable speed drive (VSD). Air flow is controlled via a velocity probe – regulating a VSD can result in a 40 % reduction in power consumption.
Grydale approached SMEC Power & Technology in 2019 to provide a custom-built enclosure to suit their dust collecting rigs utilising a 1000V variable speed drive, enclosure design was required to operate in extreme dusty and harsh environments throughout the Sydney tunnelling projects.
SMEC Power & Technology designed a custom enclosure, utilising forced cooling keeping the enclosure positively pressurised to negate dust entry and offering a high degree of enclosure cooling and IP rating.
The Magnetek GP1000-E 1000V VVVF 260kW and 450kW drives were utilised for this project.
Over the last 4 years SMEC Power & Technology have supplied Grydale multiple 450kW & 260kW Magnetek GP1000-E 1000V Drives in custom built enclosures, providing continuous operation today throughout the Sydney tunnelling projects.
Magnetek 450kW GP1000-E 1000V VVVF drive controlling 450kW motor & centrifugal fan to regulate air flow via velocity probe.
Magnetek 450kW GP1000-E 1000V drive with inbuilt line reactor, tuned harmonic filter, DC bus choke and forced cooling – installed on the JMS-60 M series dust collectors.
