Bulk Liquid Oxygen U.S.P. Storage Systems

Bulk Liquid Oxygen U.S.P.

Praxair offers storage facilities and reserve supplies for its Medipure® brand
cryogenic liquid Oxygen U.S.P. to meet current NFPA standards. Bulk storage units
and either liquid or high-pressure cylinder reserve supplies are sized specifically
to your facility based on usage patterns and geography. Control equipment is
maintenance-friendly and designed to provide interruption-free service.

In addition to providing equipment to meet NFPA requirements, Praxair’s Tracker™
remote inventory monitoring system can provide an around-the-clock link to
our North American Logistics Center in Tonawanda, N.Y. Tracker™ continuously
monitors tank levels, automatically places your order for delivery, provides physi-
cal plant operations remote data access and can be integrated to your central
monitoring system.

Stringent production, transport and handling procedures help ensure that
Praxair’s liquid Oxygen U.S.P. meets or exceeds standards of the United States
Pharmacopoeia, as delivered to the storage tank at the hospital.

The broad acceptance of bulk liquid storage systems stems from their reliability
and compact design, making them particularly practical where hospital ground
space is limited. Praxair’s specially designed cryogenic storage tanks feature
double-walled construction with efficient insulation to minimize evaporation
losses. When gaseous Oxygen U.S.P. is needed, the liquid Oxygen U.S.P. automatically converts to gaseous form as it flows through the
vaporizer – an ambient air heat exchanger – before it enters the hospital’s distribution pipeline. An integrated backup supply system
automatically feeds gaseous Oxygen U.S. P. to the pipeline if the regular Oxygen U.S.P. supply is interrupted for any reason.

Bulk liquid Oxygen U.S.P. storage systems are available in a variety of sizes. Before Praxair recommends the most appropriate size
for any given hospital, we carefully weigh a number of critical factors including: the bed size of the hospital, the hospital’s geographic
location, the existing rate and pattern of Oxygen U.S.P. use, available installation space and accessibility of the site for transport
deliveries.

Praxair offers compact, custom fit, cost effective solutions for your bulk liquid Oxygen U.S.P. requirements:
• Automatic switching between vaporizer sections significantly reduces icing and puts less stress on the system
• Remote monitoring through Praxair’s Electronic Link Tracker™ System continuously monitors your tank level and automatically

places your order for delivery, for uninterrupted supply
• Group Purchasing Organization (GPO) benefits available to members
• Proactive support with FDA regulatory compliance
