Volcano technology has been used in several models of radiators for example in Sahara, which is characterized by the construction of pipes with a classic diameter of a circle with a diameter of 30 mm and Everest which has a 60 mm diameter. The first radiators with applied Volcano technology had circular shapes, while Kobe and Zeus-radiators which also use Volcano technology -are models with square profiles. This is a response to the current trends. We can offer 2 options: with a pressure of 3 or 10 bars, which are also available in the electrical version.
