ECM SYNCHRONIKA DUALBOILER espresso machine

The Synchronika is a machine for domestic use with a professional interior. Its technical concept is based on the system developed 70 years ago by the Italian company Faema, whose E61 equipped with it from 1961 caused a sensation at the time. With the E61, it was possible for the first time to transfer the mechanics of a hand lever machine with a pre-infusion piston system to a pump-operated device. ECM has further developed the technology of this legendary brewing group in recent years and recently patented the new type of brewing bell made of stainless steel with an extended pre-brewing cylinder.

A powerful, quiet rotary pump provides the necessary pressure. By actuating the tilt valve, the required amount of water is initially only transported into the brewing chamber and the tamped espresso flour is moistened in the portafilter. This swelling of the espresso flour is called pre-infusion, in which the aromas in the coffee are dissolved before the hot water is forced through the portafilter under high pressure (9 bar) immediately afterwards during the actual extraction. What comes out? An espresso with a perfect crema, with a balanced taste. A digital display conveniently counts the time: it should ideally take 5–8 seconds for the coffee to run.)

The Synchronika from ECM is a dual boiler machine. The water for making coffee is heated to 93 to 94 ° C in one boiler (approx. 0.75 l), and the water for the steam and hot water in the second boiler (approx. 2 l) is constantly heated to something Maintained above 120 ° C temperature. (The PID display on the machine shows the numbers for checking purposes.) So there is always enough hot water available to preheat the cups or for tea and can be tapped at the same time. If there is no need, the hot water boiler can also be switched off temporarily.
The two large, easy-to-read manometers are used to control the boiler and brewing pressure. All parts, including the housing, are made of stainless steel, with the exception of the fresh water tank with a volume of approx. 2.8 l made of white plastic. Like the gripping surfaces on the portafilter holders, the handle knobs on the toggle valves are made of black Bakelite.
