The Viola type V comprises horizontal flat-oval steel tubes of 70 x 10 x 1.5 mm and two horizontal square rear collectors of 34 x 34 x 2 mm. Between the flat-oval tubes, there is a distance of 2.5 mm, for aesthetic considerations, and to guarantee a total protection against corrosion.  Viola type V with an even number of tubes is also available with universal connection (1mm8). Ordinary radiator valves or a 50 mm valve set (with extra charge) can be fitted in that case.

As to type V1L1, one row of steel fins is spot welded on the flat-oval tubes with the aim to increase the heat emission.  The Viola is available with one row (type V1) or two rows (type V2) of flat-oval tubes.  The Viola is electrically welded by means of resistance welding robots, which gives the advantage of invisible weld-seams. The Viola V1, V2 and V1L1 are supplied with two elegant lateral coverings of painted steel plate. Adjustable wall supports are used for mounting, so the height can simply be adjusted by the installer.

The standard tube thickness of the flat-oval tubes is 1.5 mm, with a service pressure of 4 bar (test pressure 6 bar).  With a tube thickness of 2 mm, the service pressure is 10 bar (test pressure 13 bar) (with extra charge and a longer delivery time).  The maximum operating temperature is always 110°C.
