Ascaso Steel DUO PID
Unique dual-thermoblock + stainless steam boiler design with completely independent PIDs for brew and steam paths. Heat-up time is routinely under 8 minutes from cold. No cooling flush ever needed, making it one of the most forgiving HX-style machines. Extremely narrow footprint (only 27 cm wide). Available in polished stainless, black, white, or wood-accent editions. Huge aftermarket support for flow-control retrofits and custom wood upgrades. One of the few machines that can genuinely live on a regular kitchen counter without looking industrial.
