La Marzocco GB5 S 3 Group Commercial Espresso Machine, Dual Boiler, 208-240V, 1-Phase

The La Marzocco GB5 S is a 3-group commercial espresso machine crafted in Italy and designed for high-volume cafes, restaurants, and specialty coffee bars that demand consistent, repeatable espresso output across multiple simultaneous shots.

The machine is built around a dual boiler system with an 11-liter steam boiler and a 5-liter brew boiler, giving the coffee and steam circuits fully independent thermal control. Dual PID temperature regulation manages both the coffee and steam sides separately, and a digital display gives operators real-time visibility into machine parameters without guesswork. An included BWT single cartridge water filter supports water quality at the source.

The GB5 S is housed in a stainless steel cabinet with a silver finish, measuring 38.5 inches wide by 25 inches deep by 21.4 inches tall, and weighing 171 pounds. It operates on a single-phase, 208-240V electrical supply at 60 Hz, drawing 50 amperes and 6,800 watts, so kitchen teams should verify electrical capacity before installation.

It includes a 1-year warranty by the manufacturer. The machine carries UL-197, NSF-8, and CAN/CSA-C22.2 No. 109 certifications, confirming compliance with commercial kitchen safety and sanitation standards recognized in the United States and Canada.
