BFC Lira S

Lira S is BFC's multi-group machine, available from 1 to 4 groups with several control panel variants: lighted switch, electronic model with touch display, "Easy" version, and "Plus" version. The spec sheet explicitly describes a copper boiler with thermosiphon circulation and heat-balancing groups: a single service boiler feeding the groups by thermosiphon circulation, not independent boilers per group. The 2-group version with the "Standard" 11-liter boiler weighs 70 kg net and is 823 mm wide; the document does not explicitly label depth and height, listing only two shared measurements (571 and 572 mm) without indicating which is which.

On the electronic models, T.C.I. technology (Independent Temperature Control) is available, letting the operator manage and view each group's water temperature in real time from the display, with a dedicated pre-heating circuit and insulated boilers for energy savings. Declared heating power for the 2-group Standard version is 3500-4130 W depending on the mains voltage, which ranges from 220 to 240 V.

An optional automatic-probe steam dispensing system ("Turbo Steamer") is also available. The document does not specify the portafilter diameter, boiler material, operating pressure, or whether the machine connects to the mains water supply or requires a tank.
