The housing of the Orione 3000 is made of stainless steel. Exclusive filter head "Quick Mill" made of stainless steel with locking screw system and O-ring seal. Steam outlet complete with air intake to heat up drinks or for making cappuccino. Core of the construction is the legendary Quick Mill instantaneous water heater. Here the water flows through solid copper pipes with a large cross-section. However, the water only runs when you make coffee or use the steam tap. Otherwise there is no water in the thermoblock, so the water is always as fresh as the water in the tank that can be removed from the side. With this sieve carrier machine, unlike with boiler appliances, you have no old and stale water, which means no taste change and decalcification problems. Therefore 3-4 decalcifications per year are completely sufficient.
