Where most 2-group machines share a single brew boiler across both groups, the R9 gives each group its own dedicated 1.9L brew boiler and PID controller, making it the right machine for multi-roaster programs, high-volume teams, and venues where dialling in each group independently isn't a luxury; it's a requirement. Designed by Ennio Berti in Milan and built to the exacting standards Rocket is known for, the R9 is a proper working machine that also looks the part.\u003c\/p\u003e\n\u003ch2 dir=\"ltr\"\u003e\u003cspan\u003eRocket Espresso R9 Features\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003e\u003cstrong\u003eIndependent 1.9L Brew Boiler Per Group\u003c\/strong\u003e\u003cbr\u003e\u003cmeta charset=\"utf-8\"\u003eEach group head runs from its own dedicated 1.9L brew boiler, fully temperature-independent.

That kind of per-group flexibility is rare at this price point. Saturated group heads keep every shot consistent from start to finish, and the large 9L steam boiler holds up through demanding milk-drink menus without recovery delays.

Known for their uncompromising use of AISI stainless steel, precision Italian craftsmanship, and a design language that's distinctly Milan, Rocket builds machines that age well and perform harder. The R9 represents the top of their commercial ambition: per-group boiler independence, saturated-group precision, and a purposeful bar-forward design by Ennio Berti, built for the specialty cafés that demand it.\u003c\/p\u003e\n\u003ch6\u003eSplit\u003c\/h6\u003e\n\u003cstyle type=\"text\/css\"\u003e\u003c!--td {border: 1px solid #cccccc;}br {mso-data-placement:same-cell;}--\u003e\u003c\/style\u003e\n\u003ctable xmlns=\"http:\/\/www.w3.org\/1999\/xhtml\" cellspacing=\"0\" cellpadding=\"0\" dir=\"ltr\" border=\"1\" data-sheets-root=\"1\" data-sheets-baot=\"1\"\u003e\n\u003ccolgroup\u003e\n\u003ccol width=\"149\"\u003e\n\u003ccol width=\"169\"\u003e\n\u003c\/colgroup\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWarranty\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e24-months\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eHeight (inches)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e19.6\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWidth (inches)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e30\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDepth (inches)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e23.2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCup Height (inches)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3.4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eNet Weight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e100 lbs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eGross Weight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e216 lbs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSteam Boiler\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e9 L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCoffee Boiler\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2 x 1.9 L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eVoltage\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e208-240V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWattage\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e5900W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAmp Service Required\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e30A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBody Material\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eStainless steel AISI 304\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBoiler Material\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eStainless steel AISI 316L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSteam Wands\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eStainless steel + cool touch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eThermal Control\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003ePID \/ Pressure transducer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch6\u003eSplit\u003c\/h6\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/ep-shopify.s3.amazonaws.com\/related-documents\/rocket\/r9\/rocket-r9-manual.pdf\" target=\"_blank\" title=\"rocket espresso r9 manual\" rel=\"noopener\"\u003eOperating Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/ep-shopify.s3.amazonaws.com\/related-documents\/disclaimer\/web-version-equipement-warranty.pdf\" title=\"la marzocco warranty\" rel=\"noopener noreferrer\" target=\"_blank\"\u003eWarranty\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca title=\"Espresso Parts Terms \u0026amp;
