Construction and connection options

The TUBUS 3 radiator is characterized by a monolithic construction, which means that after production, it is not possible to add or remove modules. This ensures greater strength and tightness compared to assembled radiators. There are various options for connecting to the central heating installation:

• Side connection: Standard solution, ideal for replacing old cast iron radiators without the need to modify the installation.
• Cross connection: Recommended for wide radiators (over 30 modules), ensures even heat distribution.
• Central 50 mm connection: Universal solution, independent of the side of the supply and return connection.
• V-type connection: With a built-in valve insert, allows connection using standard shut-off valves – ideal for windowsill mounting with a thermostatic head at the top.
• Lower side 50 mm connection: Left or right.

The radiator tubes are made of precise steel with a diameter of 25 mm and coated with a high-quality paint coating. The maximum working pressure is 10 bar, and the permissible operating temperature is 95°C.
