Design logic of the Praktikum series

• Extended tubes with flat ends — clean, architectural rhythm
• 425×1200 format — practical horizontal presence with balanced coverage
• Black finish — confident accent with a restrained character
• Tubular construction — easy access to surfaces for maintenance

How tubular heating works

Tubular radiators are valued not only for aesthetics, but for how they distribute warmth. Tube spacing supports more even air movement through the radiator body, helping heat spread across the usable area of the room (depending on heat output and system configuration).

Because airflow through the structure is less restricted, the space can warm up faster compared to more “closed” radiator designs.

Materials and operation

Praktikum is made from steel and engineered for stable performance in water-based heating systems. The protective coating is resistant to temperature load and everyday humidity, helping the radiator preserve its exterior appearance over time. Official warranty — 5 years.
