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.\u003c\/p\u003e\n\u003cp id=\"u24421-17\"\u003eHeat 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"vc_col-sm-6 wpb_column column_container vc_column_container col no-extra-padding\" data-padding-pos=\"all\" data-has-bg-color=\"false\" data-bg-color=\"\" data-bg-opacity=\"1\" data-animation=\"\" data-delay=\"0\"\u003e\n\u003cdiv class=\"vc_column-inner\"\u003e\n\u003cdiv class=\"wpb_wrapper\"\u003e\n\u003cdiv class=\"wpb_text_column wpb_content_element\"\u003e\n\u003cdiv class=\"wpb_wrapper\"\u003e\n\u003cp id=\"u24421-19\"\u003eThe 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.\u003c\/p\u003e\n\u003cp id=\"u24421-21\"\u003eThis 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"fws_67c6867df1a25\" data-column-margin=\"default\" data-midnight=\"dark\" class=\"wpb_row vc_row-fluid vc_row\"\u003e\n\u003cdiv class=\"row-bg-wrap\" data-bg-animation=\"none\" data-bg-animation-delay=\"\" data-bg-overlay=\"false\"\u003e\n\u003cdiv class=\"inner-wrap row-bg-layer\"\u003e\n\u003cdiv class=\"row-bg viewport-desktop\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"row_col_wrap_12 col span_12 dark left\"\u003e\n\u003cdiv class=\"vc_col-sm-12 wpb_column column_container vc_column_container col no-extra-padding\" data-padding-pos=\"all\" data-has-bg-color=\"false\" data-bg-color=\"\" data-bg-opacity=\"1\" data-animation=\"\" data-delay=\"0\"\u003e\n\u003cdiv class=\"vc_column-inner\"\u003e\n\u003cdiv class=\"wpb_wrapper\"\u003e\n\u003cdiv class=\"wpb_text_column wpb_content_element\"\u003e\n\u003cdiv class=\"wpb_wrapper\"\u003e\n\u003ch3\u003e\u003cspan\u003eSYSTEM AT IDLE\u003c\/span\u003e\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"fws_67c6867df2897\" data-column-margin=\"default\" data-midnight=\"dark\" class=\"wpb_row vc_row-fluid vc_row\"\u003e\n\u003cdiv class=\"row_col_wrap_12 col span_12 dark left\"\u003e\n\u003cdiv class=\"vc_col-sm-6 wpb_column column_container vc_column_container col no-extra-padding\" data-padding-pos=\"all\" data-has-bg-color=\"false\" data-bg-color=\"\" data-bg-opacity=\"1\" data-animation=\"\" data-delay=\"0\"\u003e\n\u003cdiv class=\"vc_column-inner\"\u003e\n\u003cdiv class=\"wpb_wrapper\"\u003e\n\u003cdiv class=\"wpb_text_column wpb_content_element\"\u003e\n\u003cdiv class=\"wpb_wrapper\"\u003e\n\u003cp id=\"u24421-28\"\u003eThe group sitting at the very end of the thermo-syphon loop is a vitally important stabilizing factor.

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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"fws_67c6867df338c\" data-column-margin=\"default\" data-midnight=\"dark\" class=\"wpb_row vc_row-fluid vc_row\"\u003e\n\u003cdiv class=\"row-bg-wrap\" data-bg-animation=\"none\" data-bg-animation-delay=\"\" data-bg-overlay=\"false\"\u003e\n\u003cdiv class=\"inner-wrap row-bg-layer\"\u003e\n\u003cdiv class=\"row-bg viewport-desktop\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"row_col_wrap_12 col span_12 dark left\"\u003e\n\u003cdiv class=\"vc_col-sm-12 wpb_column column_container vc_column_container col no-extra-padding\" data-padding-pos=\"all\" data-has-bg-color=\"false\" data-bg-color=\"\" data-bg-opacity=\"1\" data-animation=\"\" data-delay=\"0\"\u003e\n\u003cdiv class=\"vc_column-inner\"\u003e\n\u003cdiv class=\"wpb_wrapper\"\u003e\n\u003cdiv class=\"wpb_text_column wpb_content_element\"\u003e\n\u003cdiv class=\"wpb_wrapper\"\u003e\n\u003ch3\u003e\u003cspan\u003eBREWING\u003c\/span\u003e\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"fws_67c6867df3a1b\" data-column-margin=\"default\" data-midnight=\"dark\" class=\"wpb_row vc_row-fluid vc_row\"\u003e\n\u003cdiv class=\"row_col_wrap_12 col span_12 dark left\"\u003e\n\u003cdiv class=\"vc_col-sm-6 wpb_column column_container vc_column_container col no-extra-padding\" data-padding-pos=\"all\" data-has-bg-color=\"false\" data-bg-color=\"\" data-bg-opacity=\"1\" data-animation=\"\" data-delay=\"0\"\u003e\n\u003cdiv class=\"vc_column-inner\"\u003e\n\u003cdiv class=\"wpb_wrapper\"\u003e\n\u003cdiv class=\"wpb_text_column wpb_content_element\"\u003e\n\u003cdiv class=\"wpb_wrapper\"\u003e\n\u003cp id=\"u24421-37\"\u003eThe 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.\u003c\/p\u003e\n\u003cp id=\"u24421-42\"\u003eThe 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.\u003c\/p\u003e\n\u003cp id=\"u24421-46\"\u003eThis 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"vc_col-sm-6 wpb_column column_container vc_column_container col no-extra-padding\" data-padding-pos=\"all\" data-has-bg-color=\"false\" data-bg-color=\"\" data-bg-opacity=\"1\" data-animation=\"\" data-delay=\"0\"\u003e\n\u003cdiv class=\"vc_column-inner\"\u003e\n\u003cdiv class=\"wpb_wrapper\"\u003e\n\u003cdiv class=\"wpb_text_column wpb_content_element\"\u003e\n\u003cdiv class=\"wpb_wrapper\"\u003e\n\u003cp id=\"u24421-55\"\u003eWhen 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.\u003c\/p\u003e\n\u003cp id=\"u24421-60\"\u003eTo 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.\u003c\/p\u003e\n\u003cp id=\"u24421-64\"\u003eThe 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 16px;\"\u003e\u003cstrong\u003e\u003cspan style=\"color: rgb(255, 0, 0);\"\u003ePlease get in contact with us if you wish to purchase this machine\u003c\/span\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 16px;\"\u003eFor more information and specifications check out:\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 16px;\"\u003e\u003ca href=\"https:\/\/keesvanderwesten.com\/mirage\/\" title=\"Mirage - kees van der westen\" aria-label=\"Visit a webpage about Mirage - kees van der westen\"\u003ehttp:\/\/www.keesvanderwesten.com\/mirage.html\u003c\/a\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Kees Van Der Westen","offers":[{"title":"2 Group","offer_id":39258704478371,"sku":"kees_2","price":16200.0,"currency_code":"AUD","in_stock":true},{"title":"3 Group","offer_id":39258704511139,"sku":"kees_3","price":18300.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0487\/2015\/0691\/files\/kees-van-der-westen-mirage-all-di-pacci-801.webp?v=1701921646","url":"https:\/\/dipacci.myshopify.com\/products\/kees-van-der-westen-mirage","provider":"Australia - Di Pacci","version":"1.0","type":"link"}
