We chose Act-in as the supplier of the OEE monitoring system in a tender due to the proven installations in the Czech Republic and abroad and the offered full-fledged, already verified product, which can also be expanded with other modules (e.g. the maintenance module Maintenance Control, PlantView and others ). I consider Act-in's ability to obtain the required data from a wide range of machinery at a good price/performance ratio to be one of the decisive points in the phase of selection and testing of a new OEE system in the company. In addition, the project was supported by a convincing reference visit, the professional appearance of experts from this company and a consulting service during the implementation of this project.
