MEDICAL GAS CABINET

Chart’s Medical Gas Cabinet is the final piece of equipment for the gasified liquid oxygen to pass through before entering the house oxygen line in the hospital. It is the command center and ensures that the oxygen storage and distribution system is functioning properly. The Medical Gas Cabinet monitors the liquid levels and pressures of the primary and secondary liquid supply tanks, and interfaces with the hospital’s alarm system.
