Di Pacci — Hand-Built Thermo-Syphon Commercial Espresso Machine
Kees van der Westen Mirage Coffee Machine
The Kees van der Westen Mirage pairs a big 13 or 19 litre copper boiler with a 4 kg brass thermo-syphon group, so it holds temperature and steam through the busiest service.
The Kees van der Westen Mirage is a hand-built commercial espresso machine made to order in the Netherlands, offered as the 2 group Duette and the 3 group Triplette. One large copper boiler (13 litres on the Duette, 19 litres on the Triplette) runs at 125°C under PID control and feeds a 450 ml heat exchanger for each group.
What sets it apart is the group. Kees van der Westen took the proven E61 thermo-syphon idea and rebuilt it with an enlarged 35 ml rear chamber, an almost 4 kg brass body and the 3-way solenoid moved inside the bodywork. Restrictors on each heat exchanger let you run each group at its own temperature, while the boiler stays hot enough for serious steam.

Key Features of the Mirage
🔥 Thermo-syphon brass groups
Each group is an almost 4 kg brass body fed by its own heat exchanger, so shot temperature stays steady even after the boiler refills.
🎯 Per-group temperature
Restrictors on each heat exchanger set group temperature, so one head can suit a light roast and another a darker blend.
🎚️ Touchpad or Bastone lever
Choose a touchpad with four programmable volumes plus continuous, or the Bastone lever with two volumes; you can swap later.
💨 Large copper boiler
13 litres on the Duette and 19 litres on the Triplette at 125°C gives deep steam reserves for back-to-back milk drinks.
🧼 Automatic backflush
A built-in program pressurises and discharges all groups together eight times, making the nightly clean quick and consistent.
🛡️ Protected heating
A safety level probe and a cut-out against the element, plus shut-down if a solenoid stays open over 120 seconds.
How the Thermo-Syphon Group Holds Temperature
The Mirage has no group pump or separate group boilers. Instead, hot water circulates on its own between each heat exchanger and its brass group, driven only by heat rising from the 125°C boiler.
- At idle, hot water rises from the 450 ml heat exchanger into the 35 ml chamber at the rear of the group, gives up heat to the 4 kg of brass and sinks back.
- A 1.5 mm restrictor slows that loop so the group settles in the low 90s°C; different or adjustable restrictors set each group to its own temperature.
- During a shot, most brew water arrives through the long, cooler lower tube and passes through the brass before reaching the coffee, which evens out temperature.
The result is a machine with the steam power of a big single boiler and group temperatures that stay put through a rush, with very little electronics between the barista and the cup.

Mirage Duette vs Triplette
Both share the same groups, controls and build. The difference is volume, power and bench length.

Most specialty cafés |
High-volume bars with two baristas on espresso |
Di Pacci recommendation: Choose the Duette for most cafés; step up to the Triplette only when you regularly run two people on espresso. Don't bother with the Mirage if you want digital pressure profiling or a fast, off-the-shelf delivery; the La Marzocco Linea PB is a quicker, simpler choice.
Best Grinders for the Mirage

Kees van der Westen Mirage Coffee Machine — Frequently Asked Questions
Does the Kees van der Westen Mirage have an E61 group?
Not a standard one. The Mirage uses Kees van der Westen's own thermo-syphon group, an updated E61-type design with an enlarged rear chamber, an almost 4 kg brass body and the 3-way solenoid moved inside the bodywork.
What is the difference between the Mirage Duette and Triplette?
The Duette is the 2 group with a 13 litre boiler and 3200 W heating, or 4800 W with the High Power option. The Triplette is the 3 group with a 19 litre boiler and 6000 W heating.
What power supply does the Mirage need?
It runs on 220 to 240 V. The standard Duette is single phase with a 15.7 A peak, so it needs a dedicated circuit rather than a standard 10 amp outlet. Confirm the Triplette and High Power supply with your electrician and with us before ordering.
Can each group run at a different temperature?
Yes. Each heat exchanger has a restrictor that sets its group's temperature, and adjustable restrictors are available, so you can run a light roast and a darker blend side by side.
What is the Bastone lever?
The Bastone is Kees van der Westen's lever for starting a shot. It offers two programmable volumes plus continuous flow, or full manual control, and can be swapped with the touchpad later.
How long does a Mirage take to arrive?
Every Mirage is made to order, so lead time depends on your configuration and colour. Contact us for a current lead time and to confirm options.
Does Di Pacci install and service the Mirage?
Yes. Our in-house service team supports commercial machines with parts in stock; contact us to discuss installation.
