The 1800 mm high efficiency vacuum tubes are of a heavy duty quality, but should always be treated with the utmost care as they are glass and can break under inappropriate treatment
Every vacuum tube has the North Solar brand engraved on it. This shows you only the original tubes are used as oppose to some generic inferior products.
Our frames are of a superior quality to others as they are manufactured from channeled aluminium. This makes them 2-3 times tougher than standard stainless steel frames. Although stainless steel frames are adequate, our independent testing demonstrated some weaknesses under Australian conditions. We do not charge extra for our aluminium frames as they have been manufactured after our testing procedures but before full manufacture runs, hence not adding extra cost to production.
