Our history
Unitech EOOD is a company with 33 years of experience in the repair and sale of turbochargers for internal combustion engines.
How we started
Our company was registered in Varna in 1993 as Unitech OOD and is the pioneer of turbocharger repair for internal combustion engines in Bulgaria.
The company’s founder, Dr Eng. Vesko Penev, lectured on turbochargers at the Technical University of Varna from 1973 to 2009.
At the dawn of the changes in Eastern Europe, he already had solid research experience and completed projects in radial turbomachinery. In 1991 he registered Radial TM – Vesko Penev to manufacture parts for turboexpanders and to repair and upgrade them.
Radial TM was the first company in Bulgaria to produce radial-inflow turbine wheels milled from a cylindrical billet. This production continued at Unitech OOD and was expanded to include parts for turbocharger repair, such as bearings, spacer sleeves, thrust washers, flingers and others.
Demand for turboexpander repairs fell after 1995 owing to the closure of a number of plants in the country. The number of partners in Unitech OOD decreased, and in 2006 the company became Unitech EOOD with a single line of business – turbocharger repair using original parts.
Martin Penev completed his engineering degree at the Technical University of Varna and joined the company in 1999. He became manager and partner in 2009, and since 2020 has been the sole owner of Unitech EOOD.
