Liquid Oxygen Converter Unit for Pressure Regulation in Medical Gas Lines

The Liquid Oxygen Converter Unit is designed to regulate oxygen pressure after its transformation from liquid to gas. In hospital oxygen systems, liquid oxygen is stored in tanks and passes through evaporators to become usable gas. After evaporation, the gas reaches a line pressure of 15 bar, which is too high for direct use inside hospital pipelines.

The converter unit ensures that this pressure is reduced to the 4 to 5 bar range, which is the standard pressure required for safe and stable distribution within medical environments.

Operating Principle and System Placement

This unit is installed after the evaporators and before the gas enters the hospital distribution network. It serves as the final stage in the liquid oxygen supply system. The gas coming from the evaporator at high pressure is safely adjusted by integrated oxygen-compatible regulators.

These regulators are engineered for high flow output and precise pressure control, ensuring that the medical gas delivered to patients and equipment is within the exact required parameters.

System Integration and Features

The Liquid Oxygen Converter Unit can be integrated with cylinder manifold systems, making it suitable for hybrid setups that utilize both bulk and cylinder-based oxygen supplies. This allows hospitals to switch sources or use both in parallel for added redundancy.

Additional features include:

• Backup system: Supports uninterrupted pressure regulation in case of regulator failure or maintenance

• High flow oxygen regulators: Engineered specifically for oxygen compatibility and high-volume gas flow

• Manifold system integration: Ensures compatibility with various hospital supply schemes
