Cryogenic Equipment and Vaporizers for Hospitals: Safe Oxygen Storage and Supply

For large multi-profile hospitals, a cylinder-based oxygen supply system is inefficient. The optimal solution is the installation of cryogenic vaporizers (bulk tanks) for storing liquid medical oxygen. Designing these units requires strict adherence to safety clearances and specialized engineering solutions.

How Does a Cryogenic System Work?

A vaporizer consists of a stainless steel inner vessel and an outer shell with a vacuum in between. Liquid oxygen at -183°C passes through an atmospheric vaporizer, turns into gas, warms up to ambient temperature, and is delivered to the hospital's pipeline through a pressure regulation station.

Site Design Requirements

According to DBN V.2.2-10:2022 and safety regulations for cryogenic liquids, the project must include:

1. Foundation: A reinforced concrete slab designed for the weight of the full tank.

2. Fencing: The site must be enclosed with non-combustible materials to prevent unauthorized access.

3. Lighting and Lightning Protection: Mandatory installation of a lightning protection system and a grounding loop.

4. Safety Zones: Maintained distances from buildings, windows, and parking lots (typically 10 to 15 meters depending on capacity).
