Description

Kees Van Der Westen machines are the most unique of gems...

...Each machine is custom fabricated by order, superbly hand-crafted with only the highest mastery and finest materials!

Heat-Exchange System

The Mirage's heating system is based on the thermo-syphon system. It consists of one large copper boiler equipped with a heat-exchanger for each group, running vertically slanted across the boiler. This heat-exchanger (HX), is connected to the rear of the group. A thick tube running from top of the HX to the group, and another tube running from rear of group all the way to bottom of the HX, complete a vertical circuit.

As the heat rises, the heated water becomes lighter and moves upwards. This is how the flow of hot water leaves the HX, entering into the thick tube attached to the top, which can then run towards the group. The group is installed slightly higher than the top of the HX. The use of the heat-exchanger equates 450cc per group.

The water in the HX is heated by the hot water and steam surrounding the HX in the large boiler. This is an extremely quick way to the heat water, thanks to the massive energy in the 125 degrees C. steam boiler, and the fast heat transferring capabilities of the copper. It is far more efficient than a heating element. The capacity of the HX therefore may remain relatively small. 

Brass Group

Each group is a massive 4kg made from brass. Brass is a top heat transferring material, which soaks up heat from the water when this enters the 35cc chamber at the rear of the group. The group becomes hot, the water losing much of its heat becomes heavier and starts to sink through the lower thick tube, running from rear of group to the bottom of the heat-exchanger, justifying superior quality of materials to complete this process.

Thermo-Syphon Loop System

This thermo-syphon loop, travelling up from heat-exchanger, (HX) to group, then returning to bottom of HX, is driven solely by the heat conducted inside the large boiler.

There is no pump or any other device. When the machine is on, and at idle, (when no coffee is being made), the thermo-syphon loop is flowing constantly all by itself. As heating the water inside a closed system also means pressure will rise, there is an expansion valve installed. This is adjusted at the workshop to start releasing drops at 11-12 bar. The group solenoid valve has a rating of 15 bars, and may act as a secondary expansion valve for extra safety.

55 years after its creation, the E61 thermo-syphon system is still considered a technically elegant system — the thermal efficiency particularly impresses and easily surpasses the popular multi-boiler systems. In comparison, the double or multi-boiler system, can technically be regarded as rather run of the mill.

For 40 years the Italian espresso machine industry, although widely adopting the thermo-syphon idea, did not take any initiative to continue its development. Instead, its innovators opted for a different route: they went back in time and revived the old idea of designating separate boilers for steam and coffee production. Kees van der Westen embodies the finest of either system.

General Features:

  • Auto-back-flush program, all groups pressurize and discharge simultaneously 8 times.
  • Energy saving hot water system. Some cold is added to the hot water, so less heated water is needed. This provides a steady stream with consistent temperature. The hot water is controlled by a quick-to-adjust timer.
  • Choice of touch pad to activate the group, offering 4 automatic volumes plus continuous, or the Bastone lever, offering 2 automatic volumes plus continuous. The touch pad can easily be swapped for a Bastone bracket, or vice versa, even later.
  • Drip tray adjustable in height, optionally a raised tray for espresso cups is available.
  • Stainless steel filter holders with KvdW POM handles.
  • PID controlled temperature, with energy saving Eco mode for nights and/or weekends.
  • Standard equipped with a Progressive Pre-Infusion Cylinder per group. This allows a finer grind, creating more surface, so a higher yield in the cup, less chance on channeling, preventing fines to travel down.
  • Offering a wide choice in filter baskets, both in terms of capacity sizes as well as type for different coffee-making experiences.
  • Rubber group gaskets remain flexible forever, do not become hard or brittle.
  • Membrane-type grouphead screen, offers very nice and even water dispersion, and creates a cleaner pull with wash shot of espresso as less coffee gets sucked up by the discharge of pressure at end of extraction. The screen remains clean for longer.
  • Heavily protected heating element for added safety, (extra safety level probe, cut-out switch with feeler against element in water, machine shuts down when any of the solenoid valves remains open for longer than 120 seconds).
  • Entire frame in stainless steel only, powder coated in crackle black.
  • Large boiler capacity: 13L with the Duette.
  • Elevated position of body, easy cleaning of bar surface.

Custom Options:

  • Bastone or Touch Pad
  • Foot Steam Petal
  • Sandblasted Logo in Side Panel
