High-end expansion tank with a borosilicate glass tube 150mm long and a direct mount for Laing D5 pumps. Modularly expandable with many options and accessories. Simple elegance meets technical grandeur The HEATKILLER Tube series is a modular collection of high-quality expansion tanks with a glass tube made of borosilicate. It has many outstanding features, which are listed below. Borosilicate glass tube With borosilicate glass, we rely on the best material currently available for the construction of expansion tanks. It offers high chemical and thermal resistance, low thermal expansion and a scratch-resistant quality. So ideal conditions for creating a high-quality expansion tank. Anti-cyclone effect Especially with popular power pumps such as the D5 or DDC, the so-called cyclone effect can occur when the cooling medium is sucked in. The pump creates a kind of whirlpool and sucks in air. This not only results in less cooling performance, but also ambient noise. With our newly developed inlay, we have effectively switched off the cyclone effect.
