Modern comfort and classic design – modular radiator TUBUS 3

The TUBUS 3 radiator from Instal Projekt combines timeless elegance and modern functionality. This modular radiator, inspired by traditional ribbed radiators, will perfectly fit into any interior – from classic to modern, and even retro. Its universal design allows it to be adapted to various arrangements, and a wide range of available sizes and colors (including the possibility of finishing with a colorless varnish) means that everyone will find the ideal model for themselves.

TUBUS 3 is distinguished by a solid steel construction and high heating efficiency – as much as 2725 W. Thanks to the possibility of choosing different ways to connect to the central heating installation (side, cross, central 50 mm, type V), installation is simple and flexible. This is an ideal solution both when replacing old radiators and in new installations. Additionally, the possibility of purchasing an electric heater transforms it into a functional hybrid model that will provide warmth all year round.

Construction and mounting possibilities

The TUBUS 3 radiator consists of 38 elements, which provides high heating power while maintaining compact dimensions (1759 mm long and 700 mm high). Made of high-quality steel, it is covered with a durable paint coating in glossy white (RAL 9003). The set includes all necessary mounting elements and an air vent. The maximum working pressure is 10 bar, which guarantees safe and reliable operation.

Pipes with a diameter of 25 mm ensure efficient flow of the heating medium. Various connection options are available:

• Side connection: standard solution, ideal for replacing old cast iron radiators without the need to rebuild the installation.
• Cross connection: recommended for wide radiators with more than 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 cartridge insert, allows easy installation using standard shut-off valves.

Quality guarantee and durability

Instal Projekt is a renowned manufacturer of central heating radiators, offering products of the highest quality. The TUBUS 3 radiator is covered by as much as a 15-year warranty, which proves its reliability and durability. The monolithic construction (no possibility of adding or removing modules) provides greater tightness and strength compared to foldable aluminum models. Additionally, dedicated mounting feet are available for purchase to reinforce the structure and provide an aesthetic finish.
