The ECM Elektronika II Profi is a heat exchange machine built for people who pull the same drinks every day and want them repeatable. Four programmable volumetric doses sit behind the control panel, so a single and a double land at the same volume every time without you watching the cup.

A rotary pump makes it quiet, and it runs from the 3 litre tank or plumbed straight into the mains, switchable either way. Temperature is held by a pressurestat rather than a PID, which is the traditional ECM approach and part of why this machine has stayed in the range so long.
