18-cam OB VAN with two expansions for Estonian Public Broadcaster / ERR

ERR is the largest media organization and government-owned radio and television public broadcasting company in Estonia. It relied on TVC experience in building highly efficient OB vans and our company proved to have all the knowledge and staff to build OB Van with unique coachbuilding design and technological solutions.


A distinctive feature of this OB Van is an efficient use of internal space. TVC applied flexible coach design approach and was capable as a coachbuilder to satisfy all ERR requirements. As a result, TVC was able to create 5 workings areas and totally 19 workplaces on a chassi-based OB van design with:

  • Main isolated equipment racks with redundant cooling system
  • Shading area (4 workplaces)
  • 2nd program area (3 workplaces)
  • Main program and slow-motion operators’ area (10 workplaces)
  • Audio room with improved sound isolation (2 workplaces).

According ERR requirements, the OB Van can operate either with one or two expanded sides. This flexibility allows to work with OB Van in a relatively narrow spaces when needed.


One full size expandable side adds an additional 1.6 m width to the body and creates a spacious working area. This expansion also creates a corridor for direct access to each area and provides a wide passage between two exterior doors. Second expansion adds 0.65 m distance between main production crew and video wall. In the scenario where 2nd expansion is not expanded, the motorized main production desk can be pulled out from the video wall for an additional 400 mm. The production desk can be stopped at any desired point from 0 to 400mm.


One more feature that TVC is proud of - an improved fully electric side expansion and self-levelling system, which takes much less time to deploy than previous versions. Over time fully electric side expansion and self-levelling system has proven to be very convenient and easy to maintain for users.

Power, HVAC, lighting, and control systems were individually designed based on Estonian climatic conditions, installed equipment and number of workplaces.
