Via Ocel ltd was founded in the year 2000 as enterprise for manufacturing, engineering, sales, export and import Via Ocel took part in realization of significant international projects of modernization, reconstruction and development of district heating system in Belgrade So far enterprise done many miles of hot water pipe systems, hundreds of district heating system connections and almost 30% of total substations reconstructed in Belgrade

In 2007, significant part of our activities have been focused on thermo energy. Beside manufacture and delivering parts for substantial 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 handling systems for coal, slug and ash …all in order to increase energy efficacy, reliability and extend life of coal mill equipment and FD and ID fans; above all, to reduce pollution and emission of environment unfriendly gases.

DEVELOPMENT

Production and erection of thermo technical facilities Production and assembly pressure for steam boilers capacity greater than 500t/h Basic and detailed engineering on thermo technical and thermo energetic facilities Design and delivery Steam pipe lines for steam boilers capacity greater than 500 t/h Engineering and production development Rehabilitation and upgrading projects Design and production of pressure Parts,coal mills and ID/FD fans

Our development is based on modern direction which anticipates increasing the efficiency, reliability and environmental-friendly design of utilities. Development and research are reflected in the following fields: development of new manufacturing and technological procedures, development of ecological technologies, development of new technologies and products

Mentioned settings are fulfilled in the following utilities: boilers with supercritical parameters where increased steam parameters result in increased efficiency in electric generation in coal fired power plants, combined generation of electric energy and heat in co-generating power plants, utilization of waste heat used for steam or heat generation, modern waste incinerating plants as one of possible solution of waste disposal, biomass, agricultural and wood waste, firing boilers (other prospective possibility to generate heat) using combustible waste of farm and wood processing products.
