The insert heaters must always be placed horizontally, completely below the liquid level and supported at a length of > 750 mm. If it is placed vertically, this should be discussed in advance due to the minimum liquid level. It is possible to produce the unheated zone of the closed tube elements with 120, 150, 200, 250, 300, 400 or 500 mm. The maximum surface load must be observed at all times, which is why this must be discussed and checked when ordering.
