Product Description Breville BES840XL the Infuser Semi-Automatic Espresso Machine is a superbly engineered appliance with graceful lines and expertly crafted fit and finish. The designers at Breville have incorporated the best features that an espresso machine requires and fine tuned those features to give you an affordable luxury that is robust, beautiful, and produces wonderful espresso. Starting with essential pre-infusion to wet and expand the grounds gently a few seconds before high pressure brewing the BES840XL has it spot-on. Pre-infusion releases the full flavor of the bean. The 15 bar Italian pump forces brewing water through an energy efficient Integrated stainless steel water coil where a 1600W thermocoil, managed by an electronic PID temperature control for increased temperature stability, heats the water to critically precise brewing temperature for excellent extraction of everything your coffee has to offer. The one-piece aluminum thermo coil is cast around a coil of stainless steel tubing wound around a coiled ceramic-coated electrical heating element. The one-piece thermo-coil is a major improvement over the previous 2 piece thermo-block designs.
