While we’ve seen PIDs implemented on heat exchange espresso machines before (primarily as a method for managing the steam boiler’s pressure versus being able to effectively manage brew temperature,) the Pasquini Livia G4 also incorporates an additional thermoblock at the brew head so that you can actually manage the brew temperature. The PID interfaces with the steam boiler, which in turn affects the water in the heat exchange, supplying a thermoblock at the group head with pre-heated water. The result? Markedly improved temperature regulation and the ability to produce more consistent espresso shots.
The new LIvia G4 series also incorporates a few other changes: Expanded cup warming surface, weight-based water reservoir sensor, a super sexy portafilter and increased steaming functionality. It’s also available in three different formats — the standard Semi-Auto without a PID, a Semi-Auto with a PID and an Auto with a PID — so you can take advantage of some or all of the upgrades Pasquini has made to their Livia series.
