M21 Junior is a machine designed and built for those who, although have limited space at their disposal, still want to offer traditional Italian-style espresso coffee and cappuccino.  It is a one-group machine for small production needs, available both in an automatic (M21 Junior DT) and semi-automatic (M21 Junior S) version.  M21 Junior S is a continuous semi-automatic machine, equipped with a vibration pump, a boiler water auto-level and an automatic valve.  Unlike the DT, the S can’t be linked directly to water mains, instead it is equipped with a built-in tank and a water softener, to solve those situations where a permanent connection to the mains is not possible or desired.
