Rancilio Classe 20 ASB Tall 2 Group Commercial Barista Espresso Machine

Advanced multi-boiler espresso technology with independent group temperatures, touchscreen control and serious commercial capacity.

The Rancilio Classe 20 ASB Tall is a premium 2-group commercial espresso machine designed for busy cafés, coffee shops, restaurants and hospitality businesses that want greater control over extraction temperature and consistency.

Advanced Steady Brew gives each brewing group its own micro-boiler and heating element, allowing different temperatures to be set independently through the touchscreen. Combined with an 11-litre steam boiler, Tall groups and powerful steam performance, the Classe 20 is built for demanding professional coffee service.

Advanced Steady Brew Multi-Boiler Technology

The ASB version of the Classe 20 uses Rancilio's Advanced Steady Brew system.

Each brewing group has its own 150ml micro-boiler and dedicated heating element, helping maintain a stable temperature across both the brewing water and the group itself.

Different extraction temperatures can be set independently for each group directly through the machine interface, giving baristas greater flexibility when working with different coffees, blends or roast profiles.

---

Independent Temperature Control for Each Group

The two independent brewing groups can operate at different temperatures at the same time.

That makes the Classe 20 particularly useful for businesses serving more than one coffee – for example, running a house espresso through one group while configuring the other around a guest coffee or lighter roast.

---

4.3-Inch Touchscreen Control

A 4.3-inch touchscreen gives quick access to coffee settings, hot-water parameters and machine controls.

Dedicated digital displays on each brewing group then keep important extraction information directly in front of the barista during service.

---

11-Litre Steam Boiler + Independent Coffee Micro-Boilers

The 2-group Classe 20 ASB combines an 11-litre steam boiler with two independent 150ml coffee micro-boilers.

Separating the coffee boilers from steam production improves thermal performance when espresso extraction and milk steaming are happening simultaneously – exactly the sort of workload expected in a busy commercial environment.

---

Tall Groups for Takeaway Cups

The Tall configuration accommodates cups up to 145mm high, making it well suited to takeaway drinks and larger milk-based coffees.

Extractable rise plates allow traditional espresso cups to be positioned closer to the group heads when required.

---

Cool-Touch Steam Wands & C-Lever Control

The Classe 20 ASB Tall uses thermally insulated cool-touch steam wands with Rancilio's C-Lever controls.

The C-Lever requires only a short 25-degree movement. Lift it for continuous steam or press it down for steam that stops automatically when released.

This gives the barista quick, intuitive control while the insulated steam-wand construction improves handling and helps reduce milk residue baking onto the outside of the wand.

---

Programmable Hot Water with X-Tea

Rancilio's X-Tea system allows hot-water doses and temperature levels to be programmed through the interface.

This supports more consistent preparation of Americanos, teas and other hot-water drinks alongside espresso service.

---

Advanced Boiler Management

Advanced Boiler Management is designed to support machine performance during intensive use.

When espresso extraction, hot-water delivery and milk steaming are taking place simultaneously, the system manages heating and boiler pressure to help maintain consistent performance.
