Medical Oxygen

Twice the nitrogen capacity for smaller, more energy efficient units

Honeywell UOP developed the first commercially viable adsorbent for medical oxygen applications more than 40 years ago. Today, UOP’s OXYSIV™ molecular sieve adsorbents help make smaller and more energy efficient medical oxygen concentrators to meet patient needs more effectively.

UOP molecular sieves for medical oxygen applications include:

  • OXYSIV 5XP – Provides efficient performance for stationary and transportable concentrators
  • OXYSIV MDX – Molecular sieve with high N2 removal capacity and selectivity to optimize performance for all concentrators, including portables

In a concentrator, air passes through a packed bed of OXYSIV where nitrogen is adsorbed, concentrating the 20% atmospheric oxygen to 90% or greater.

MDX is a lithium-exchanged molecular sieve that provides twice the nitrogen capacity of earlier adsorbents and permits the design of the smallest, most energy efficient units. This technology has enabled a new class of portable oxygen concentrators.
