Europafilter solved the operational reliability issues of the transformer sheet cutter at ABB Ludvika Hydraulics by installing offline oil filtration systems, available in Australia exclusively from Basil V R Greatrex .
A black and brown coloured coating continued to form on the pilotslid component of the transformer sheet cutter. This sticky substance caused the pilotslid to lock in the valve circuit, which caused the valve to hang and malfunction.
Even after calling a service man in to trim the system, the problem continued.
Europafilter offline oil filitration systems were assembled in the oil reservoir of the transformer sheet cutter, a hydraulic machine used for cutting transformer steel sheets. The filitration systems ensured that the oil cleaning process occurred continuously while the machine was in operation.
A short time later, the troubles with the hydraulic system had ceased and they have not reappeared.
