The La Cimbali M21 coffee machine is a fairly simple espresso machine, with a lot of La Cimbali unique features in it. As mentioned above there are 2 model versions, the S and the DT. In this case the Cimbali M21 junior S is the non volumetric tank version. Where the Cimbali M21 Junior DT is the volumetric model with main water supply. There are a lot of resemblances between both models, but also a lot of differences. Below we will try to explain the differences between them.

La Cimbali M21 Junior DT

The M21 Junior DT is a single group espresso machine with a Heat Exchanger (HX) boiler. The HX system is unique to espresso machines made by La Cimbali. On the side of the boiler is a flange welded, where also the brewing group bolts onto. But in that flange the HX tube is installed and held in place when the brewing group is bolted on it’s place.

So the brewing group is part of the HX system and can be completely disassembled, which makes cleaning and replacing parts easier then with for instance a welded HX. This brewing group is a solenoid operated group head and has mostly standard Cimbali spare parts. For the M21 Junior models you can use a standard La Cimbali portafilter.

The M21 junior DT is available with a 110V and a 230V heating element. This heating element produces 1800W of power, which is plenty enough for such a small espresso machine. on the boiler you will find a variety of fittings, tubing and valves. Valves such as a steam valve, water valve, vacuum valve and a safety valve.  This heating element has been fitted with a safety thermostat, made by the German company Ego. The control of the heating element is done with a pressure switch, this is not a standard switch made by Asco or Parker. But their own design, which is used for decades.

The La Cimbali M21 Junior DT is fitted with a main water connection and hasn’t been fitted wit a water tank on the back. So this espresso machine does have a pump and motor assembly. The motor is made by the Italian company RPM and the pump by the company Procon(you can also use pumps made by Fluid o tech/Rotoflow or Nuert).

Because the M21 Junior DT is a volumetric espresso machine you need to have a flowmeter installed. This flowmeter is installed just before the tubing goes towards the brewing group.

Besides a flowmeter it does require also a variety of electronic components such as a dosing device/level regulator and the touchpanel for the coffee selection.


La Cimbali junior M21 S

This version of the La Cimbali Junior is the non volumetric model of the Junior, but that is not all. A Heat Exchanger (HX) boiler is featured in the M21 Junior S, which is an espresso machine with a single group. La Cimbali espresso machines are the only ones that are equipped with the HX technology. A flange has been welded onto the side of the boiler, and here is where the brewing group will bolt onto it. However, the HX tube is inserted in that flange, and it is held in place when the brewing group is mounted on top of it in its proper location.

Therefore, the brewing group is included in the HX system and is able to be taken apart entirely. Because of this, it is much simpler to clean and replace components in a HX that is not welded, for example. The brewing group in question is a solenoid-operated group head, and the majority of its spare parts are standard Cimbali components. A La Cimbali portafilter in its usual configuration can be utilised with the M21 Junior versions.

There is a heating element for either 110V or 230V power available for the M21 junior S. This heating element generates 1800 watts of electricity, which is more than plenty for a machine of this size that makes espresso. On the boiler, you will discover a selection of valves, fittings, and tubing in a variety of sizes. Valves like steam valves, water valves, vacuum valves and safety valves are all examples of valves.  This heating element features a safety thermostat that was manufactured by the German business Ego and it has been installed. A pressure switch is used to operate the heating element; however, this particular switch is not a conventional model and was not manufactured by Asco or Parker. However, it is their original design, which has been in use for many years.

What the M21 Junior S makes different from the DT version is that this espresso machine has been fitted with a water tank on the back, but no connection to the main water supply. The water from this water tank is pumped with a Ulka vibration pump to the boiler and brewing group. This model of espresso machine doesn’t have a flowmeter, so it is a non volumetric model.

This means that it is fitted with a push button for making coffee, with this button you can only start and stop the brewing process. This won’t stop automatically such happens with the M21 Junior DT.


Cimbali Junior

The la Cimbali Junior does look quite similar to the M21 junior, but it is not the same espresso machine. always check the part reference numbers to verify that the components are compatible with each other.
