This system is designed for small to medium sized stores. It has the purification system inside of the dispenser.

This makes up to 1 gallon per minute of purified water and dispenses up to 5 gallons per minute into the container.

This can also supply water for other store use such as produce misting, meat fogging, bakery ovens, proffers and coffee etc.
This can also be used with the commercial back room purification system, for much higher volume stores.
