Product Description
The GB5 has redefined the standard for temperature stability in modern espresso equipment. A dynamic preheater assembly ensures that water entering the coffee boiler is at precisely 170° F. 170° F water replaces hot water exiting the group, reducing temperature swings in the coffee boiler.?An algorithm-based PID temperature controller further reduces temperature fluctuation in the coffee boiler. A group cap designed by Piero Bambi and an integrated ruby flow restrictor reduces channeling and ensures that water never leaves the saturated area of the coffee boiler, eliminating the introduction of temperature instability during the brewing process.
