The Zehnder Tetris design radiator is the winner of the prestigious Red Dot Design Award 2024. It stands out for its combination of iconic design and perfect functionality given by the unique internal structure that allows for two-sided counter-flow of the medium inside the radiator, so that the radiator is heated evenly over the entire surface up to the ends of the tubes. The robust construction and ingenious tube layout enable fast deep drying of towels. Ideal for low-temperature systems. Fast heat up, excellent power up to 1 kW.
