Manual dosing lets the operator start and stop each shot by hand, which means you can adjust pull length on the fly for different beans, grind settings, or customer requests. The self-tamping, high-density group heads compress the puck consistently, and Astra's thermocycling system paired with a 7 liter copper boiler holds brew temperature steady through sustained service.\u003c\/p\u003e\n \n \u003ch3\u003eThermocycling System for Barista-Grade Temperature Stability\u003c\/h3\u003e\n \u003cp\u003eAstra's thermocycling system continuously circulates water through the high-density group heads, eliminating the temperature swings that plague conventional machines between pulls. For a semi-automatic where the barista is making real-time decisions about grind and extraction, having a stable, predictable brew temperature is what makes those adjustments meaningful rather than guesswork. The 7 liter copper boiler transfers heat rapidly and recovers quickly, keeping you ready for the next shot even during peak rushes.\u003c\/p\u003e\n \n \u003cp\u003eThe M2S-017 comes equipped with three steam wands and one hot water valve, with manual steam controls (automated option available) and manual hot water controls. Ships with one single and two double portafilters. A quiet rotary-vane Procon pump connects to a plumbed water line (30 to 50 psi, filtered and softened) through a 1\/4-inch inlet and 1\/2-inch drain hookup. 220V, 4500W, dedicated circuit required, 5-foot power cord included. Handcrafted in the USA from US-standard parts.\u003c\/p\u003e","brand":"Astra Manufacturing","offers":[{"title":"Default Title","offer_id":51175780122909,"sku":"M2S-017","price":5645.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0699\/4716\/2909\/files\/40868_m2s017_front_e36d89a7-e9fd-498e-a7a6-4fc4fe6f4104.jpg?v=1776338586","url":"https:\/\/thechefstore.com\/products\/astra-m2s-017-mega-ii-semi-automatic-espresso-machine-two-group-heads-220v","provider":"TheChefStore.Com","version":"1.0","type":"link"}
