Widely recognized as a pinnacle of performance and design, the Kees Van der Westen Spirit Duette 2 Group espresso coffee machine stands out on several key factors: sweeping modern classic design, the super advanced copper multi-boiler configuration, the ability to run either timed shot pours or volumetric shot pours, or just the sheer wow factor of the uniquely Dutch design. Developed as a machine that cannot be run out in even the busiest peak period, the Spirit Duette provides passionate baristas with complete control over steam boiler temperature, main brew boiler temperature, and group head boiler temperature - resulting in a thermal stability that has no rival. This specific unit was only in service for about a year. Works great!
