KEES VAN DER WESTEN SLIM JIM IDROCOMPRESSO

The Slim Jim Idrocompresso by Kees van der Westen (KvdW) is a pinnacle of espresso engineering, melding the tactile, artisan soul of spring-lever extraction with the industrial stability of 316L stainless steel multi-boiler technology. It is a machine built for the specialty barista who values the classic "theatrical" lever workflow but requires the uncompromising thermal accuracy of a modern PID-controlled system.

Key Performance Benefits

Lever Group Evolution: The Idrocompresso re-engineers the classic spring-lever. By moving the lever position away from the barista and incorporating a safe, thumb-operated locking mechanism, KvdW has eliminated the danger of accidental "kicks" while providing the consistent, decaying-pressure profile that lever machines are famous for.
PEEK Piston Technology: The lower part of the piston is crafted from PEEK, a heat-neutral polymer. This ensures the piston does not absorb heat from the brew water, keeping the thermal system perfectly stable even during high-volume sessions.
Precision PID Control: Each group is thermally independent and monitored by a PID system that "learns" the heating cycle, allowing for ±0.1°C temperature adjustments via the digital interface.
Safety-First Hydraulic Logic: The brain of the machine prevents heating until both the steam and coffee boilers are confirmed full, protecting the heating elements from dry-firing. If a group solenoid is triggered for over 3 minutes, the machine automatically shuts off the group to prevent damage.
Visual Diagnostics: Every group features a shot timer and a pressure gauge, while individual control lights at the base of the machine provide instant visual confirmation that each heating spiral is functioning correctly.
