Coffee boiler: 0.8 L water capacity | 316L stainless steel | Steam boiler: 3.5 L water capacity | 316L stainless steel | Pump and motor: Circular pump | Water tank: 3.5 L water capacity | 316L stainless steel | Power settings: Normal\/Low power* | Voltage (single phase): 220-240 V | Frequency: 50\/60 Hz | Maximum power: 230 V 50 Hz \/ 2500 W | Spiritello offers a dual boiler system. Both boilers are made of 316L stainless steel, which is more resistant to strong water pressure than 304 stainless steel and has a longer lifespan in espresso machines. Each boiler can be switched on or off independently. The filter holders are also made of stainless steel. | Both boilers can be easily drained via a ball valve. The coffee boiler drain is connected to a drain tray, while a hose connection is provided for draining the steam boiler. A large steam boiler with a total capacity of 3.5 liters. Combined with two 900W heating coils controlled by a PID system, this ensures powerful and long-lasting steam. Hot water is mixed with a little cold water to deliver a non-splashing flow from the nozzle at the touch of a button. The final temperature can be easily adjusted using a screwdriver via a slot in the machine’s body. The amount of hot water can also be adjusted via the display. | The steam valve has a rotating knob available in our four standard colors to match the rest of your accessories. The steam wand is made of double-walled stainless steel and finished with a PEEK tip, ensuring that milk won’t burn on it. | The coffee boiler, integrated with the group, is a large, one-piece unit with a capacity of 0.8 liters and a 450W heating element controlled by a PID system. This saturated setting ensures extremely precise temperature control. Cold water first passes through a cross-flow (hot-cold) heat exchanger to be preheated to a temperature close to that of the coffee boiler before entering it. All welding is performed internally and externally to ensure there are no cracks that could cause corrosion. Our approach is to create a precise water temperature and then ensure that no heat is lost on its way to the coffee pod. The coffee boiler and set are one large unit, and the temperature is controlled by a PID sensor. The Idrocompresso cylinder and piston are located inside the set and are completely surrounded by a generous supply of the same water that will flow into the chamber when the lever is pulled. The bottom of the piston is made of completely thermally neutral PEEK, so the water loses no heat and the piston doesn’t get dirty. | The coffee boiler is supplied with preheated water from the heat exchanger in the steam boiler. All parts are made of stainless steel (316L in water contact areas). Stainless steel has approximately ten times less heat transfer capacity than copper, so no heat is lost to the surrounding metal. | Spiritello provides an internal pump. It is a stainless steel rotary pump powered by a 180W motor suitable for continuous operation. This pump first pushes the water through a manually adjustable pressure reducer, then to the heat exchanger in the steam boiler, followed by the coffee boiler, and finally to the brewing chamber below the piston. Preheating the water via a heat exchanger allows for the use of a small coffee kettle, yet ensures that the target coffee temperature is maintained easily and accurately, even during intensive and rapid operation. When the machine is connected to the main water supply, water flows directly to the pump, and the pre-hydration pressure remains fully adjustable. When the main water pressure is sufficient (minimum 3 bar), the user can disconnect the pump, resulting in a completely silent machine, but this may limit the pre-hydration pressure range. The pump is also used to fill the steam boiler and add some cold water when drawing hot water from the spout. When the lever is pulled into the locked position, the solenoid valve and pump are activated, and water immediately flows into the brewing chamber under the piston and onto the coffee disc. As long as the lever remains locked, the pump operates. The pump pressure can be adjusted from 1.5 to 4 bar using the large pre-hydration adjustment knob. When the lever is released, the pump stops, and the spring, along with the piston, begins to force water through the coffee. The piston has three PEEK discs for securing the V-rings. PEEK discs make ring replacement easy, do not absorb heat, and remain clean for a very long time. The extraction process can be stopped at any time by pressing a button next to the set.<\/p>","protected":false},"excerpt":{"rendered":"
