Kees van der Westen Slim Jim Duette – 2-Group Multi-Boiler Café Machine

Kees van der Westen Slim Jim Duette for a two-barista bar

A two-group layout suits the venue where one person pulls shots while the other steams. On the Duette, each head has a dedicated stainless brew boiler under its own PID, so both stations hold their set temperature even when milk orders stack up.

Shared steam, separate brewing

A 10.5-litre stainless steam boiler feeds the wands and hot water outlet, and incoming brew water is preheated on the way through a balanced heat exchanger. Pull a bastone lever and the group runs one of two stored volumes, starting with a gentle pressure build that rewards a finer grind. Big timers under each group let staff dial in by numbers rather than guesswork.

Designed around your brand

Front and side panels, legs, cup rails, awnings, colours and handles can all be specified, and because the parts interchange, a later refit does not mean a new machine. ECO settings can sleep one boiler or the lot, with programmable start and stop times for weekends.

Who should choose the Duette?

It fits two-staff cafés with steady volume and venues wanting a showpiece counter. Venues needing a third head can step up to the Slim Jim Triplette. Browse more commercial coffee machines, add a commercial grinder, and keep specialty beans on hand.
