Liquid Oxygen Systems: Certified Cryogenic Storage for Hospitals

Liquid Oxygen Systems are essential infrastructure for medical facilities requiring continuous, high-volume oxygen supply. Designed for the cryogenic storage of liquid oxygen (LOX), these systems are built with a focus on safety, insulation, and compliance with international medical and industrial standards.

Tecnomed’s LOX tanks offer a durable and efficient solution to meet the oxygen demands of hospitals and healthcare centers.

Tank Structure and Materials

Each cryogenic tank used in Liquid Oxygen Systems consists of two concentric vessels:

• The inner vessel, which holds the liquid oxygen, is made of stainless steel, ensuring durability and chemical compatibility.

• The outer vessel is manufactured for insulation and structural protection.

To achieve thermal insulation between these two chambers, the interspace is filled with perlite and vacuum-sealed. This dual-layer structure prevents heat ingress and reduces evaporation, maintaining stable cryogenic conditions.

Storage Capacities and Hospital Use

In hospital settings, Liquid Oxygen Systems are commonly available in the following storage volumes:

• 3,000 liters

• 5,000 liters

• 10,000 liters

• 15,000 liters

• 25,000 liters

These capacities can be customized based on facility oxygen demand, number of patient beds, or system redundancy needs. Whether for primary supply or as part of a hybrid setup with cylinder systems, Tecnomed tanks offer scalable options.

International Certification and Compliance

Tecnomed’s LOX tanks are designed and manufactured in full accordance with:

• EN 13458-2 – Cryogenic vessels for refrigerated liquefied gases

• 2014/68/EU – Pressure Equipment Directive (PED)

Each tank is also certified by Türk Loydu, an internationally recognized inspection and classification body. This ensures the tanks meet both European and global pressure vessel safety standards.

Application and Integration in Medical Systems

Liquid Oxygen Systems are widely used in:

• Large hospitals

• University clinics

• Emergency oxygen backup stations

• Mobile or field medical units

The system connects to the main medical gas distribution network, allowing vaporized oxygen to be delivered to various departments such as ICUs, operating rooms, and general wards.

Thanks to its vacuum-insulated structure, the tank minimizes evaporation loss, ensuring efficient and economical usage over long periods.
