There is also a 150mm version, but unfortunately La Cimbali does not provide documentation indicating which length version is used in a model by model comparison. However, if you need to order one of these, it is likely that the unit is not functional, and removing the exchanger to measure your existing one should not present a problem: it needs to be removed regardless and then you can measure it.
