Special Feature: On Exchange Basis

This is a facilitation technique that, when our customer asks for the repair of his governor, our company provides him, temporarily, with a proprietary and fully functional same type governor, until his one is fully repaired. This feature intends to facilitate the customer and the proper function of his vessel, while not charging at all for the lending of our governor! In case the customer’s governor is not repairable, then, if he wishes, he is able to be extra charged, so as to buy ours.


For the best service of our customers, we provide a large stock of our field's items, such as governors, fuel oil injectors and nozzles, fuel oil pump plungers and repair sets. Moreover, in case customer’s demand includes non-stock items, we can order them, upon request.


Since 2007, we have relocated our facilities in a new, fully-fledged building, at Industrial Park of Schisto, in the outskirts of Athens. Inside our 1000 sq.m. building, we have separate sectors, each one dedicated to a specific repair industry. All sectors are both autonomous and fully equipped with latest machine tools, as well as always being under the supervision and management of a technical expert.
