VBM DS1GMA2BSWIN Double Domobar V4.0 Manual Espresso Machine - Boiler
FeaturesDouble 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 Vibiemmes 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.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.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 oz. 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 in. male thread.Dimension - 21 x 10.6 x 16.5 in.SpecificationHeavy 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.Boiler pressure gauge to indicate steam boiler pressure. The setting can be varied by adjusting the pressurstat (V3.5 or earlier).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 electroni
