Description

Since 2008, Vibiemme has worked diligently with importers, distributors, and industry professionals to upgrade their Double Domobar double boiler espresso machine. 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.

Steam Boiler Pre-Heat: Here is the kicker on other double boiler machines, especially those with a preheat of water through the steam boiler before it enters the coffee boiler. This design is to reduce the temperature fluctuations in the coffee boiler. However, one issue occurs! The incoming water to the coffee boiler can be at a lower temperature when the steam boiler is off. Thus, with the same programmed PID settings, the coffee boiler may not react fast enough to maintain temperature.

Since 2016, Vibiemme’s solution was to have a temperature management system whereby the coffee boiler has 2 heating elements – 600 watt plus 300 watt. When the steam boiler is powered, the system only uses the 600 watt or 300 watt element in the coffee boiler to maintain temperature. However, when the steam boielr is off and there is no preheat of the water entering the coffee boiler, the Vibiemme double boiler uses both coffee boiler heating elements to manage the temperature being changed by the incoming colder water.

Upgraded Safety Valve on Steam Boiler: Since 2016, all Vibiemme double boilers have an upgraded safety valve on the steam boiler that opens up at 2 bar to prevent any excessive steam pressure out. This was to allow the programmed PID to elevate the steam boiler to a higher pressure to produce greater steam! In addition, the steam boiler was upgraded to withstand the higher steam pressure. Without the upgrade, the boiler walls would bow out, weakening the silver solder, and then creating leaks. The PID on the steam boiler can be programmed to 1.5 bar pressure. Coupled with a large 1.9 copper boiler and a standard commercial steam pipe, the throughput and capacity are there for superior performance. The steam pipe is not a no-burn wand because no-burn wands have half the diameter of the throughput of a standard pipe.

In fact, look at our PID overview sheet. With the steam boiler set at 1.5, you can also program the F.05 setting (steam boiler offset) to have the steam pressure go past 2 bar! However, the steam boiler safety valve will start releasing steam at 2.0-2.2 bar. So, be careful when adjusting the steam boiler offset. This feature was inside machines made from 2016 and on!

Version 4.0 now has both boilers, coffee and steam, fully insulated and PID managed. The drip tray cover has been enhanced with a hole to reduce ‘splatter’ from the 3 way valve extended below the grouphead. The former versions 3.5 and below had a pressurstat to control the steam boiler.

Please note this machine ships on a pallet with curbside delivery only. It is just to heavy for UPS or FedEx to handle properly with the care you deserve on a high end purchase.

TOP FEATURES that brings the Vibiemme Domobar Super Double Boiler espresso machine to the TOP!

  • Double boilers: the user can operate the coffee boiler alone or the coffee and steam boiler together.
  • PID (Proportional, Integral, Derivative): This allows you to manage temperature control of the coffee boiler and steam boiler. If you are not sure what PID is, here is an overview.
  • Small water reservoir (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. For those who believe the small boiler makes better coffee because of fresh water displacement, we have a smaller reservoir for the same reason.
  • PLUMB-ABLE Inbound water!!! – The machine can be used in reservoir mode or direct plumbed mode. The machine comes with an inlet stainless steel inlet cold water hose to plumb your machine into your water line. Contact us for water treatment options as well as requirements to connect!
  • Over pressure valve (OPV): Feeds excess water pressure to the drip tray and not the water reservoir. This will allow operation of the direct water connection without having the reservoir fill with overflow water which can get moldy and require constant emptying and cleaning.
  • Plumbable Drip tray: Slides out easily to drain out or can be connected to a drain with changing of included adapter and attachment of included drain hose!
  • Insulation on coffee boiler / steam boiler: Helps save energy. The insulation on the coffee boiler also aids in temperature stability for the espresso extraction.
  • Only up to 15 amps required: Without the need for any additional switches or internal adjustments.
  • Commercial-grade rotary vane pump: With the ability to make a direct water connection or use a water reservoir on the same machine with the movement of a lever under the machine. Includes stainless steel braided hose with 3/8″ male thread.
  • User programmed offset: The temperature regulation is at the coffee boiler, and the grouphead always has a lower temp. This feature allows the user to program this delta in temperature as every environment has a different offset.

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: 1 single spout portafilter with a 1-cup filter basket and 1 double spout portafilter with a 2-cup filter basket.
  • Coffee boiler capacity / material: 0.5 liter copper boiler. This very small coffee boiler allows quicker displacement of any stale water as possibly found on larger coffee boilers for machines in this class. Boiler temperature controlled by PID.
  • Steam boiler capacity / material: 1.9 liter copper boiler and temperature controlled by PID.
  • Boiler pressure gauge: Indicates steam boiler pressure.
  • Pump pressure gauge: Indicates brew pressure during espresso extraction (reading will vary while not extracting).
  • Multi-directional stainless steel steam wand: Located on the left side and can be moved in different directions.
  • Multi-directional stainless steel hot water wand: Located on the right side and can be moved in different directions.
  • Power light: Located on the right side and indicates when the machine is powered on.
  • Heating light: Located on left side and indicates when espresso machine is heating.
  • Water light: Located in the middle and indicates when water level in water reservoir in rear is low.
  • Three stage power switch: Three stage power switch allows user to operate espresso machine with coffee boiler only or both boilers simultaneously
  • Extremely large stainless steel drip tray: 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: Reacts to a .02 C of temperature change in the coffee boiler.
  • Rotary vane pump and commercial-grade motor: 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 the body panel, the 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.
  • Accessories included: Single spout portafilter, 1-cup filter basket, double spout portafilter, 2-cup filter basket, blind filter basket (for backflushing), plastic coffee scoop, and a common useless plastic tamper (please make sure to order a good tamper).

Notes

  1. Switch stages: To avoid any confusion on the operation of the machine:
    • Stage 0: Machine is off except low water light ‘may’ come on if water tank has low water.
    • Stage 1 w/ PID OFF: Brew boiler OFF and steam boiler OFF – used for initial refill without damaging the heating elements in either boiler.
    • Stage 1 w/ PID ON: Brew boiler ON and steam boiler OFF.
    • Stage 2 w/ PID OFF: Brew boiler OFF and steam boiler ON.
    • Stage 2 w/ PID ON: Brew boiler ON and steam boiler ON.
  2. No burn wands: 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.
  3. 220 volt version: Sorry, 220-240 volt units are not available for ordering.
  4. Some assembly required: Feet are not attached to the machine.
  5. Direct connect mode:
    1. Setup: There is a screw in the water tank plate that the user can tighten to hold the plate down so the switch is activated to make the machine think there is water in the reservoir.
    2. Connecting water line: Water connection at bottom of machine is in the back left corner ~2″ from the rear and ~5 inches from the left side panel. The water connection elbow under the machine is 1/4″ male thread. The included stainless steel braided hose, is 46″ long and has the female fitting to connect to the water connection elbow. On the opposite end of the braided hose, there is a 3/8″ female thread fitting. It is best to purchase the V319 coupling to attach to your water line, and then attach the braided hose to the V319 coupling.
    3. Draining: This model has the capability to drain or not to drain. There is an included plug on the back of the drip tray. The plug can be removed or installed as desired. The machine’s drain pipe can be manually directed to drain either to the right or left side of the machine. In either direction, the drain pipe can be angled 4″ from either side. The included drain hose is 46″ in length and has a 1/4-3/8th inside diameter which slips onto the machine’s drain pipe. The drain hose needs to drop vertically 1″ for every 12″ it goes horizontal.
    4. Water line pressure: Should be regulated to be between 35 and 40 pounds for proper operation of this machine. Check with your local plumbing supply to advise on purchase so as to meet any local building codes. In addition, check with them about your local building code may require a backflow preventer (which does not allow boiler water to backflow into water supply).
    5. Water supply: Connection must be made to a cold water supply line only.

2 reviews for Vibiemme Dual PID Double Boiler Domobar Commercial Espresso Machine V4 w/ Rotary Pump

  1. 5 out of 5

    I bought this machine to replace a popular E61-type lever machine with which I had struggled for shot volume and temperature consistency. I chose the VBM DD because of its optimized power control method for 110V/15A and the smaller boilers, which would enable quicker recovery. The PID controls on both boilers were also a big plus, as was the fact that 1st-line had worked so closely with the manufacturer to fine-tune the machine's hardware and performance.

    I've been very pleased with the purchase. I typically make three double lattes each morning: two with almond milk, one with whole dairy milk. The pre-infusion capability (I'm plumbed into line pressure water) is a great addition and the extractions are consistently luscious. I use a scale to weigh my shots in progress and the ability to control volumetric output with the control lever directly addresses the biggest complaint I had with my old machine.

    Steam performance is also very satisfying once I figured out I was using poor technique inherited from my old setup. After making the necessary changes I found I could get great microfoam in both types of milk with little effort.

    Overall this is a high-quality machine with superior performance and, by way of 1st-line's involvement, almost a direct line to the manufacturer if you have any questions or concerns.

    New Vibiemme v3 Double Boiler***for a previous version***

    Just got the new Double Boiler and used the direct connect option. I've been happy with a Silvia for many years and upgraded more for the added convenience and direct connect.

    Added convenience is great, but the quality of the espresso, foam and the machine is well beyond anything I had imagined. Somehow it extracts more flavor and sweetness, yet leaves the bitter and undesirable out.

    First shot was fantastic. Adjusted grind, even better. Added a few degrees to the PID, better still.

    Foam too was considerably better, with a silky texture and micro bubbles that I have never seen -faster too.

    The ""tank like"" quality from VBM was obvious - as my son said ""this thing is legit"".

    Moving from a Silvia to the VBM, same 25 second shot required 2-3 clicks finer on the Rocky.

    Tasting with friends we were impressed with more than half an inch of crema on a double shot of decaf, plus two other distinct layers beneath the crema. Caramel, tan and brown colors streamed from the portafilter that none of us had seen like this before. The crema was so thick it reminded me of a Guiness from the tap.

    The VBM DB is levels above. Rich chocolate notes that run from dark to milk chocolate as you drink it, kind of the way flavors evolve when drinking a great wine. All agreed, hands down the best that we had ever tasted.

    Did the direct connect myself. It was easy although I had to install a pressure reducer (a $70 part (Watt 26A) on the 3/8 inch copper line).

    I am so impressed with this machine and recommend it highly. After years deciding which machine to get, I was leaning towards a VBM DB, but was sold on the v3 with the PID and direct connect/reservoir capability. That, coupled with the recommendation from Jim at 1st-Line (he has given me solid advice for over a decade) pushed me over the edge. Hard to imagine anyone being disappointed with this machine.

    First step, please descale your machine in tank mode. Remove body cover by removing three screws on each side. Follow the hose behind the spout and look for the source of where the water is coming from.

    Second step, test the machine in tank mode with the plumbing disconnected from the machine and power off. There should be no leaks.

    Third step, power on machine for several hours and look for the leak in the hose. If there is a leak, then the boiler may be overfilled or the boiler refill valve is partially open allowing water to back track to the OPV. If there is water exiting the safety valve or vacuum breaker valve on top of the boiler, then the boiler is overfilling which points to a bad sensor, bad brain unit, or faulty wiring.

    Fourth, if no leaks in tank mode, reconnect direct plumbing water supply and leave power off. If it leaks, then to points to the OPV (check hose to drip tray spout) or overfilling of boiler as described above. If no leaks, power on and check. If it leaks at this point, then it is most likely an overfilling boiler.

    You can check for an overfilled boiler (steam side) by removing slowly hot water from the hot water spigot. Within a few ounces, the pump should kick in. If not, then the boiler could be overfilled.

    As soon as the pump kicks in, shut the hot water valve. In a few seconds, the pump should stop. If the pump stays on, it could be overfilling the boiler. To physically check, the machine needs to be cold , unplugged from the electrical outlet, and the direct water supply turned off, then remove the vacuum breaker valve and inspect visually.
