2. Via Ocel ltd was founded in the 2000 as an enterprise for manufacturing, engineering, sales, export and import In the period up to 2006 Via Ocel took part in realization of significant international projects related to modernization, reconstruction and development of district heating system in Belgrade So far, enterprise has done many miles of hot water pipe systems, hundreds of district heating system connections and almost 50% of total substations reconstructed in Belgrade History

3. In 2007, beside previously mentioned activities, the significant part of our activities has been focused on thermal power plants. Beside manufacturing, erection and delivery of parts for system upgrading and overhaul in power plants, services have been provided in a field of basic, detailed and reversed engineering such as: pressure parts fossil fuel firing equipment boiler pipe systems and steam lines transport and coal handling systems, ash and slag …with the aim to increase energy efficiency, reliability and to extend life of coal mill equipment, FD and ID fans, and above all, to reduce pollution and emission of environmentally unfriendly gases. History

4. Today, Via Ocel has become leading company in Serbia for material supply of power plants and facilities and the largest pressure parts producer in the region. Today Via Ocel has more than 170 employes with 24 engineers. In order to provide wider scope of services, Via Ocel has entered in partnership with an engineering company Balkan Energy Team (BET). Via Ocel has become owner of shares in company Balkan Energy Team. Besides BET Via Ocel has shares in ownership in following companies: -Takovo Transport – Company for transport and logistic -Arc Monte – Mechanical erection company Via Ocel has a Cooperation agreement with Babcock Borsig Steinmüller.
