This is a Kees Van Der Western espresso machine. The Mirage Duette is the 2 group of the family and the Mirage Triplette is the 3 group. You’ll find these coffee machines pumping out coffee in the more serious of coffee places.
It has a unique styling which grabs anyones attention. It has E61 group heads with pre-infusion. There are a number of options which can be fined tuned for what you like, such as foot pedals for your steam wand etc. Please contact us for this sort of requirement.
- 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 mix provides a steady, non-spattering stream with the correct temperature to prepare Americanos.
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 channelling, preventing fines to travel down. - Wide choice in filter baskets, both sizes as types.
- Rubber group gaskets remain flexible forever, do not become hard or brittle.
- Membrane type group screen, very nice dispersion, less coffee sucked up by discharge of pressure at end of extraction. Remains clean longer.
-
Heavily protected heating element (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: 13ltr. with Duette, 19ltr. for the Triplette.
- Elevated position of body, easy cleaning of bar surface.
BOILER – HEAT-EXCHANGER – GROUP
The Mirage`s heating system is based on the so-called thermo-syphon system. It consists of one large copper boiler (13ltr for the Duette, 19ltr for the Triplette), equipped with a heat-exchanger for each group, running vertically slanted across the boiler.
This HX is connected to the rear of the group by a thick tube running from top of HX to group and another tube running from rear of group to bottom of HX, completing a vertical circuit.
THERMO-SYPHON LOOP AT WORK
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 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. We use HX`s of 450cc per group.
Heat always wants to go up: the heated water becomes lighter and moves upwards. This flow of hot water leaves the HX, enters the thick tube attached to the top of the HX, then runs towards the group. The group is installed slightly higher than the top of the HX. The group is a massive piece of almost 4 kg of brass. Brass being a very good heat transferring material, 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 becoming heavier and starts to sink through the lower thick tube, running from rear of group to the bottom of the HX. Arriving there, the water re-enters the HX, heats up again and all starts anew. The temperature inside the HX is much higher than the normal operating temperature for the group. Capacity to heat the group is thus ensured very well.
This thermo-syphon loop, travelling up from HX to group, then returning to bottom of HX, is driven solely by the heat inside the large boiler. There is no pump or any other device. When the machine is on and at idle (no coffee 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 bar and may act as a secondary expansion valve for extra safety.
SYSTEM AT IDLE
The group sitting at the very end of the thermo-syphon loop is a vitally important stabilizing factor. It is after all the last part water travels through before hitting the coffee, during brewing. Its temperature therefore is important and should be very close to the desired temperature of the brewing water.
The temperature of the group body can be adjusted simply by having more or less hot water flow through its rear chamber. The temperature inside the HX being quite a bit higher than the desired temperature for the group, the thermo-syphon loop needs to slow down, needs to be restricted.
With the Mirage we adjust the boiler to 125 degrees Celsius. To get the group body temperature at low nineties we install a standard restrictor at the top of the HX with a passage of 1.5mm.
With different restrictors installed it is quite possible to operate one machine with temperatures adjusted differently from group to group, for example to accommodate for the use of lighter and darker roasted coffees. As an option we offer adjustable restrictors.
One also may attempt to change the group temperature by changing the boiler temperature, but this method is limited because fairly large boiler temperature changes are needed to realize just a little effect at the group. Also the steam or hot water capacity of the boiler may be affected that way. With the proper restrictor one can for example easily combine the extremes of 1.5 bar high steam power with a low 88 degrees C. brew temperature.
BREWING
The challenge of the thermo-syphon system is to get water of low nineties temperature to the coffee, provided by a HX that stores water at 125 degrees. The extra heat is needed to keep the group at its perfect temperature, the remaining heat is needed to deliver brewing water of the correct temperature. To start the brew process the group solenoid valve opens the path from the thermo-syphon system towards the coffee in the filter holder. At the same moment the pump starts to run, keeping the pressure at a steady 9 bar, everywhere between pump and coffee.
The sudden exit, provided by the open solenoid valve, has a drastic result. All water will now flow to that exit, pushed out by the pump pressure. The flow in the lower tube changes direction, it flows upwards to the group, instead of downwards to the bottom of the HX. The flow in the upper tube remains the same. The crucially important second function of the restrictor now becomes clear. The flow through the upper tube towards the group is severely restricted by the1.5mm orifice of the restrictor. The lower tube does not have any restriction, it has an inside diameter of 8mm. This full-flow 8mm, compared to the 1.5mm, means 99% of the water reaching the group arrives via the lower tube.
This suits the requirements very well, since this lower tube contains the cooler water (generally 88-92 degrees, compared to the upper tube 115-125 degrees). To get the most out of this, we install a very long lower tube in the Mirage, containing 30cc. The remaining water comes directly from the HX. All water leaving the HX is replaced simultaneously by fresh cold water. The hot water leaves the HX through the lower tube, from bottom of HX. The cold water enters the HX also through the bottom. The cross flow of outgoing hot and incoming cold water is used to help each other. As there is just a 1mm copper wall between these 2 flows, the outgoing hot water is cooled down considerably, losing its heat to the incoming cold which starts to heat up right away. The cold water is forced to travel to the top of the HX via a long injection tube.
When leaving the top of the injection tube it needs to travel down again to the bottom of the HX, during brewing. This ensures the heating capability of the HX is used to its full capacity. Naturally, the cooling down of the water from HX to lower tube by the crossflow is not a very precise process, as the temperature of the cold water can vary because of climate, location, season, etc. It will however be a major drop to well below 100 C. Travelling upwards through the long lower tube offers a good start to further stabilise. When entering the big brass group body the temperature of the water will be easily stabilized to the correct temperature of the group.
To facilitate this temperature stabilization process we changed the insides of the group to increase the contact of water with the group body as much as possible. During brewing the water first passes the 35cc chamber in the rear of the group, then runs to the solenoid valve from where it re-enters the group. It fills the infusion chamber, passes through the passages towards dispersion fitting and finally is pressed through the group membrane- type screen.
The stabilizing ability of the mass of 4kg brass is impressive. Even after taking a bucket of hot water from the main boiler, causing this to cool down for a short while during re-filling with cold water, the energy stored within the brass ensures enough shots of the correct temperature to allow the boiler to regain its standard temperature. When starting a shot, we recommend to draw a short flush: 30-45cc. Never flush more, because the water runs much faster through the entire system during a flush. When flushing longer the inherent stability of the system can easily be ruined, requiring at least 5 minutes to completely restore.

Product Assessment for warranty repair.
Once proof of purchase has been established, if the product fault can safely and clearly be determined, we will offer you either a refund, exchange or repair. The available remedy will depend on whether the fault amounts to a major failure. In some instances, we may need to consult with the manufacturer or importer to determine the fault and resolution. Most faults can be easily repaired within a reasonable time frame. We will not offer a repair or replacement if the product has been damaged via misuse or abuse. Examples include but are not limited to inadequately filtered water, lime scaling, corrosion due to high chloride ion concentrations in water, operator errors, unauthorised repair work or modification and fair wear and tear.
Whist we understand that many clients would like a loan machine in the event of a warranty item, we regret that this service is not available. We prioritise all warranty work over general repair to ensure the most rapid service possible.
- Where there is no fault found, the product will be made available for collection by the customer.
- When assessing product fault, it is up to you whether you would prefer to deal with Di Pacci Coffee or the manufacturer or importer directly. It may be more convenient for you to liaise with the manufacturer or importer directly (which may be more time efficient). You certainly have that option. We are happy to provide you with their relevant contact details to assist you.
