In the central system, the supply source of N2O-O2 is located in a storage area (tank room) separate from the treatment rooms. Flowmeters and the accessory equipment required for the delivery of the gases reside in the treatment rooms.
Flowmeters are mounted into a cabinet, on a wall arm or placed on a mobile stand for easy transfer to other operatories. Gas cylinders are maintained in a tank room and gas is delivered to the individual treatment rooms through copper pipes. Because the cylinders are stored in a location separate from the treatment rooms, larger "G" and "H" size cylinders are employed. The "G" and "H" cylinders hold approximately ten times the amount of gas contained in the "E" cylinders associated with the mobile system. Multiple treatment rooms can be connected through copper piping to the tank room and operated from this bank of cylinders.
One of the advantages of the central system is the flexibility it offers. Multiple operatories can be plumbed for N2O-O2, and one or more flowmeters can provide service to all. If dedicated flowmeters are preferred they can be purchased when the system is installed (or over time to accommodate practice growth). The central system is particularly attractive to offices where nitrous oxide is used on a regular basis and available space will accommodate a tank room. Economically speaking, the savings obtained over time from the use of larger gas cylinders will offset the initial investment in a central storage system.
