Vibiemme has worked diligently with importers, distributors, and industry professionals in the past year to upgrade their Double Boiler line. One of the main requirements was to design and build a dual boiler espresso machine that would not have any compromises at 15 amps electrical service when compared to 20 amps. Why compromise? Version 4.0 now has both boilers, coffee and steam, fully insulated. The drip tray cover has been enhanced with a hole to reduce 'splatter' from the 3 way valve extended below the grouphead. Version 4.0 has changed and removed the pressurstat and the PID is now connected to the boiler to control the boiler pressure. TOP FEATURES that brings the Vibiemme Domobar Super Double Boiler espresso machine to the TOP! Double boilers - the user can operate a coffee boiler and steam boiler independently of each other. Seriously, many double boilers have the water fro the coffee boiler pass through the steam boiler first to get pre-heated. If you turn off the steam boiler on those machines, that water is colder and can affect temperature performance. With the dual heating element in the Vibiemme's coffee boiler, the steam boiler does not have to be powered on as the extra element will provide more power to heat the coffee boiler. Did we say that the coffee boiler was 0.5 liters? Smaller means more turnover to of fresh incoming water? Heat exchanger machines were very popular due to the increased water turnover. PID (Proportional, Integral, Derivative) allows user to manage temperature control of the coffee boiler . If you are not sure what PID is, here is an overview. Water reservoir at 2.1 liters allows approximately 20 double shots to be extracted without a refill - refill can occur on the fly while the machine is operating. OPV (over pressure valve) feeds excess water pressure to the drip tray and not the water reservoir - this will allow operation of the direct water connection with having the reservoir fill with overflow water, get moldy, and require constant emptying and cleaning. The 54 ounce drip tray can be drained manually or connected to a drain WITHOUT purchasing any optional kits. Insulation on coffee and steam boilers helps save energy Water does not have to be placed in the reservoir, nor does any wiring under the drip tray have to be reconfigured for the machine to function in direct connect mode Only up to 15 amps required without any additional switches or internal adjustments. Commercial-grade motor and rotary vane pump with ability to make a direct water connection or use a water reservoir on the same machine. Includes stainless steel braided hose with 3/8" male thread. Note: We have decided to NOT offer no-burn steam wands because the typical internal diameter is about 50% less than a normal steam wand, and this usually affects performance times in steaming. In addition, the grouphead has a much greater area to get burned. In addition to achieving optimal temperature stability, one of Vibiemme’s main goals when redesigning their double boiler machine was to keep the amperage requirement below the 15 amp mark - not only making it easier to find a connection in any household without needing a dedicated 20 amp circuit, but also to keep energy consumption at a minimum. Thanks to an innovative method of controlling the percentage of power to the heating elements, Vibiemme’s Power Management Control System (PMCS) automatically regulates variable power to each heating element. The total amperage draw of the machine will never go over 15 amps using 110-120 volts. Quality Characteristics and Specifications found Vibiemme Style Heavy duty true Vibiemme E61 grouphead maintains active flow of water from the grouphead to the heat exchanger in the boiler Professional grade brass portafilters - one portafilter with single spout and single filter basket and one portafilter with dual spout and double filter basket Coffee boiler capacity/material: 0.5 liter copper boiler Steam boiler capacity/material: 1.9 liter copper boiler Steam boiler temperature and pressure is regulated by the PID controller - after much testing, it was decided to replace the smaller pressurestat with the PID sensor and new controller. Sorry, the older style is not forward compatible to this new design. Boiler pressure gauge to indicate steam boiler pressure. The setting can be varied by adjusting the pressurstat (V3.5 or earlier) - please note the body panel has to be removed as there is a new international safety standard that Vibiemme has manufactured this machine under, and the standard requires that no access port be allowed for changing the pressurstat setting. Pump pressure gauge to indicate brew pressure during espresso extraction (reading will vary while not extracting) Multi-directional stainless steel steam wand on left side can be moved in different direction Steam tip has four holes Multi-directional stainless steel hot water wand on right side can be moved in different directions Power indicator light on right side indicates when the machine is powered on Heating light on left side indicates when espresso machine is heating Low water level light in middle indicates when water level in water reservoir in rear is low Three stage power switch allows user to operate espresso machine with coffee boiler only, with steam boiler only, OR with both boilers simultaneously (awaiting confirmation once shipment arrives) Jaeger pressurstat monitors boiler pressure in steam boiler (Version 3.5 or earlier) No pressurstat for Version 4.0. Extremely large stainless steel drip tray which can be easily (slides out with pull of handle) removed for cleaning. Grate stays on machine when pulling out drip tray so that it is one step removal to empty. GICAR branded electronic water level control and reacts to a .02 of C of temperature change in the coffee boiler Rotary vane pump and commercial-grade motor is quieter than a vibration pump, but it is more expensive to replace. hence, descaling is important OPV (over pressure valve opens when too much pump pressure exists) located in rear of machine with easy access when body panel and six (6) associated screws and divider are removed. Although the pump has an adjustment screw for regulation, the OPV is an additional feature to manage overflow that may be caused by overpressure from the water company when the machine is plumbed in.

Technical Information: 1 Domobar super Double Boiler technical details – 2011 version 1.1 Coffee boiler technical details: Coffee boiler: 0.5 liters Coffee boiler element: 900 watts total Thermic insulation by silicon glass Working temperature for testing: 93 C° (200 F) Safety Thermostat stops power at 110 C° (230 F) The coffee boiler is situated vertically, and at the time of this writing, this is the smallest coffee boiler that we know of on a prosumer/commercial double boiler espresso machine - as with heat exchangers, less water standing water means superior cup profiles. After many months of testing, Vibiemme found this configuration (boiler size and wattage) to provide the optimal temperature stability with both scenarions: steam boiler on or steam boiler off. 1.2 Steam boiler technical details: Steam boiler: 1.9 liters The steam boiler is placed horizontally Steam boiler element: 1,200 watts total Pre-heating exchanger for coffee boiler*: 45 ml ( approx. a double espresso) Thermic insulation by silicon glass Working Pressure: 1.2 bar Safety valve working max. pressure: 1.5 bar *Inside the horizontal steam boiler’s lower part where the water is located, there is a heat exchanger pipe which pre-heats water for the coffee boiler: water outlet temperature 97°C (208°F) for pressures higher than 1 bar. The pre-heating exchanger pipe is horizontal in the horizontal steam boiler to avoid any of the higher temperature steam transferred by the upper portion of the vertical steam boiler as found on other double boiler machines. In theory, the heat exchange pipe portion in the steam portion of a vertical steam boiler will turn into steam, and this can cause an unwanted variation in the temperature of the water to the coffee boiler when the machine has been idling too long. 1.3 Electronic box and Gicar probe: User controlled setting via front panel: 1°C or 1°F Probe sensitivity: a tenth of C° or a tenth of F° Stainless steel probe in coffee boiler 1.4 PID Settings for Testing (and adjustable by user):: Temperature: 200°F P: 1.0 I: 0.00 D: 0.5 Offset: 19°F 1.5 Fresh water supply configuration: The machine has a dual water-supply system. The user can use the internal water reservoir or connect to an existing water line (water softener recommended). Both options on the same machine utilize a rotary pump. A mechanical lever, located under the machine, allows the end-user to choose their inbound water supply. 1.6 Waste-water drainage system The machine has a dual drainage system: the end-user can drain the waste water into the drip tray (and manually empty it out) or connect it directly to an existing drain system. 2 Thermic stability trial of the Domobar Super Double Boiler: tools, procedures and validation. Important Definition: What is thermic stability ? Thermic stability is the one of most important features on a PID double boiler espresso machine; it is the difference among the maximum temperatures recorded in a shot sequence.Differences between 2C° and 3C° have to be considered as acceptable, between 1C° and 2C° good, below 1C° excellent: these values create the thermic stability range, which depends on the manufacturing features of the machine. 2.1 Tools: Thermic stability values can be detected through a measuring instrument for temperatures (SCACEII), placed at the group exit, following a world renowned testing pattern as outlined on the next section. 2.2 Procedures: the trial was made referring to a world class and standardized testing pattern Test Point 1 2 3 - 4 5 - 6 7 - 8 9 - 14 Idle Interval (mm:ss) 10:00 5:00 2:00 1:00 0:30 0:10 The "Test point” corresponds to one shot of 50 ml double espresso brewed in 25 seconds. The "Idle Interval” is the time between one shot (end) and the beginning of the other. The test is made by recording the maximum temperatures of test points 1-14, respecting the idle intervals. The differences among the maximum temperatures recorded from test point 1 to test point 14 give as a result the values of the thermic stability range. 2.3 Validation Besides checking the Domobar Super Double Boiler thermic stability values, the test aims to confirm the empirical model of the E61 group isothermy in an idle state, published on home-barista http://isotherm.blogspot.com/. This model states that when the idle Interval is longer than 2 minutes, the temperature difference between the red part (where the thermosiphonic circulation takes place in an idle state) and the blue part ( the farthest and coldest part), is approx. 7 °F. This is the basic principle of the pre-shot, suggested to all users of E61 espresso coffee machines. 3. DOMOBAR SUPER Double Boiler Version 3 - THERMIC STABILITY TEST RESULTS : Confirmation of the empirical on E61 grouphead isothermy and Domobar Super Double Boiler stability test’s report 3.1 Confirmation of the empirical model on group E61 isothermy The thermic stability tests made on the Domobar Super Double Boiler confirm the isothermic model on group: the E61 group must be "taken to the right temperature” when the idle Interval is longer than 2 minutes. The temperature difference between Test Point 1-14 maximum temperatures and the thermic stability range (test point 6-14) is 7° F (without pre-shots).This data has to consider as a project feature of the E61 group, so the meaning of the thermic stability data has to take this feature into consideration. 3.1 Domobar Super Double Boiler stability test’s report Domobar super Double Boiler stability range with steam boiler ON :1° C (1,5°-1,8° F) Domobar super Double Boiler stability range with steam boiler OFF :1° C (1,5°-1,8° F) 4. DOMOBAR SUPER Double Boiler THERMIC STABILITY TEST: Consumptions and absorptions Maximum absorption with steam boiler ON: 1600 watts Maximum absorption with steam boiler OFF: 900 watts 5. HOW DOES THE NEW DOMOBAR SUPER Double Boiler WORK? The Domobar Super Double Boiler can be used in different power configurations: Steam boiler ON and Coffee boiler ON Steam boiler OFF and Coffee boiler ON Both configurations are available with: a) Water fills through existing direct water connection or plumbed in line (a water softener is always recommended) b) Water fills through water reservoir c) Water drains into the drip tray d) Water drain through existing drainage system In case of both boilers ON (thanks to coffee boiler water pre-heating function), thermic stability range of 1°C can be kept even on shots taken every 10 seconds with less wattage utilized within the coffee boiler. Vibiemme can finally state that the testing pattern was successfully passed with up to 900 watts absorption. In the case of the steam boiler OFF, thermic stability range of 1°C with varying watts absorption of up to 900 watts.
