La Marzocco Linea Classic S Commercial Espresso Machine (4 Group)

The four-group Linea Classic S is specified for the busiest sites La Marzocco builds for: stadium concourses, airport kiosks, university unions and any bar where three groups run out of road. Four saturated groups on dual insulated boilers, with independent PID on both the coffee and steam circuits.

Why the Classic S earns its place

• Four saturated group heads: every group sits in permanent thermal equilibrium with the coffee boiler rather than being heated separately, so brew temperature holds across all four positions no matter how many are firing at once.
• Dual insulated boilers: the coffee and steam circuits run independently, so multiple baristas texturing simultaneously never pull temperature out of the brew side. Insulation cuts standby energy draw on a machine that stays on all day.
• Dual PID control: separate PID controllers on the coffee and steam boilers let you dial brew temperature to the roast and set steam pressure to suit your milk programme.
• Half-turn steam valve: a 180° lever gets you from closed to full steam in one motion.
• Water conductivity sensor: the machine monitors incoming water hardness and conductivity, giving early warning before scale becomes a service call.
• La Marzocco Pro App: the electronic board supports connectivity with the Pro App for remote monitoring, scheduling and diagnostics.

Choosing your configuration

• EE (Semi-Automatic): a single on/off switch per group, with the barista controlling the shot directly.
• MP (Mechanical Paddle): a manual paddle per group giving direct control over pre-infusion and flow, with no volumetric dosing.
• AV (Auto-Volumetric): programmable volumetric doses per group with flow-meter control. At four groups and multiple staff on bar, volumetric control is the practical choice for consistency and waste control.

Best suited to

Stadiums, airports, transit hubs, large campus and corporate sites, and multi-barista flagship cafés.

Requires a dedicated 50 A circuit and careful counter planning at 46 in wide. Custom RAL colours are available on the side and back panels to special order; base and chassis remain black. Contact us to confirm current lead time.
