KEES VAN DER WESTEN SPIRITELLO

The Kees van der Westen (KvdW) Spiritello is a sophisticated dual-boiler lever espresso machine that blends the tactile, artisan experience of a traditional spring-lever group with the modern precision of PID-controlled stainless steel technology. Designed for those who demand uncompromising build quality and temperature stability, the Spiritello is a masterclass in hydraulic engineering and professional performance.

Tension: 220–240 V | 50–60 Hz (1-phase).

Core Technology

Dual Boiler System: Independent 316L stainless steel boilers provide superior resistance to aggressive water and long-term durability. Each boiler can be toggled on/off individually, and both are easily drained via dedicated ball valves.
Saturated Group Design: The group and coffee boiler are integrated into a single, massive 0.8L unit. Cold water is pre-heated through a steam boiler heat-exchanger, ensuring precise, near-brew-temperature water enters the coffee boiler.
Lever Group Dynamics: The spring-lever system features a PEEK-piston a heat-neutral material that prevents temperature loss and residue buildup. Users can control pre-infusion pressure (1.5–4 bar) via an adjustable knob, while the pump handles saturation and initial extraction.
Silent Operation: If the water mains pressure is 3 bar or higher, the pump can be disengaged, allowing for a completely silent brewing experience powered by the lever’s spring mechanism.

Temperature & Flow Stability

Thermal Efficiency: By utilizing 316L stainless steel instead of traditional brass, the machine reduces heat transfer to the surrounding environment by nearly tenfold, ensuring heat stays exactly where it’s needed: at the coffee puck.
Advanced Steaming: The large 3.5L steam boiler, controlled by PID, delivers powerful, long-lasting steam. The double-walled stainless steel wand, finished with a PEEK tip, prevents milk from burning or sticking.
Hot Water Precision: Features a mix-manifold that combines boiling water from the boiler with cold water to provide a steady, non-spattering flow. Both the temperature (via an adjustable restrictor) and the dispensing quantity (via digital display) are fully customizable.

Build & Safety

Construction: All internal components and welds are finished to eliminate crevices, significantly reducing the risk of corrosion.
Hydraulic Flow: An automatic air-bleed system ensures trapped air is expelled during group activation, maintaining a consistent column of water for reliable extraction.
Intuitive Interface: Features a digital display for adjusting flushing quantities, steam/water settings, and Eco-mode functionality.
