A beverage dispensing unit is provided. The beverage dispensing unit may include an upper cabinet configured to house a first plurality of beverage containers, a cold beverage chassis, a hot beverage chassis, and one or more user interfaces configured to receive a beverage request from a user, a lower cabinet configured to house a second plurality of beverage containers, a flash heater including a boiler configured to heat water and one or more beverage coils configured to be submerged in the hot water to heat one or more beverages respectively disposed in the beverage coils, a cold exchange unit containing a water tank and a second beverage coil contained within the water tank to chill a beverage contained with the beverage coil, and a flash chiller configured to chill water and circulate cold water to the cold exchange unit to fill the water tank.

The present disclosure relates to a method for the sanitization of a beverage dispensing system comprising the following steps: feeding a vessel of an electrolytic cell with an aqueous solution; interrupting said feeding step, so that a predetermined quantity of said aqueous solution is inside said vessel; activating an electrolysis process inside said vessel, so as to transform said predetermined quantity of said aqueous solution into a quantity of sanitizing solution; and introducing said quantity of sanitizing solution into at least one duct of said beverage dispensing system.

A system for sanitising a fluid pathway in a drinking water dispensing assembly may include: a supply of water to be delivered under pressure through the fluid pathway; and a sanitising solution to be dispensed into the fluid pathway via a flow restrictor. The flow restrictor is configured to regulate the flow rate of the solution delivered to the fluid pathway to facilitate mixing between the water and the solution to an effective sanitising concentration within the fluid pathway.
