Liquid Oxygen Supply for Medium Sized Hospital

All Saints HealthCare is a 128 bed hospital located in North Hollywood, CA. They investigated a bulk tank system to replace their existing oxygen system, and chose Chart to help them upgrade their capabilities. The result was decreased labor costs, lower operational expenses, and increased security and safety.

Situation and Design Challenges:

All Saints HealthCare used a gas feed system to deliver medical-grade oxygen throughout the hospital. The existing system was fed from a manifold that connected to six liquid cylinder tanks and vaporizers. Each liquid cylinder weighed 250 pounds, was about five feet tall, and had to be manually wheeled back and forth from the loading dock to replenish the liquid oxygen. This process was so labor-intensive to keep a constant supply of gas flowing, All Saints dedicated three full-time employees (one per shift) to manually load and unload cylinders. In addition, there were potential safety and ergonomic issues when dealing with the cylinders – up to 500 pounds when full.

Solution and Results:

All Saints also wanted a more secure source of oxygen, to reduce concerns about interrupted service or pressure fluctuations. They chose a Chart 9000 gallon horizontal storage tank as their main supply of LOX (Liquid Oxygen) and a horizontal 1500 gallon tank as their reserve supply. Chart worked with All Saints to help them procure a complete system that would plug directly into their existing pipeline, eliminating the need for cylinder swaps. John-Paul Sensibile, Administrator for All Saints, said that Chart provided “excellent engineering, installation and post install support.”

Since oxygen is piped in directly to the storage tank, vaporized, and fed into the hospital system, All Saints eliminated cylinder exchange hassles, and were able to reassign the three full-time employees to more productive work. This reduced their total labor and maintenance costs while increasing the safety conditions for their employees.
