Adsorbents for refrigerant drying: Heroes of Chemistry

Historically, UOP’s XH™ desiccants have set the refrigerant drying standards for cost effectiveness and high operating reliability in automotive and stationary refrigeration systems.

We know that uncontrolled system moisture in refrigeration can freeze capillary tubes and expansion valves, corrode metal parts with acids formed by hydrolysis and plug expansion devices with sludge. Water can enter a system when it is manufactured or over time via hoses, fittings and other components.

UOP molecular sieve desiccants prevent system failures by controlling this type of contamination. We also serve your changing needs for:

  • Superb drying capacity
  • Compatibility with specific refrigerants and lubricants with our volatile reactions
  • High mechanical strength
  • Particle integrity to prevent crushing or attrition especially in high vibration applications like automotive air conditioning
  • Cost effectiveness
  • High reliability

When the 1987 Montreal Protocol mandated non-CFC refrigerants, UOP responded with outstanding UOP XH-7™ and XH-9™ desiccants that allowed the entire industry to meet the legislated deadlines. In March 1998, the American Chemical Society recognized this contribution by awarding its prestigious “Heroes of Chemistry” award to our development team.

UOP remains the world’s leading supplier of molecular sieve desiccants for air conditioning and refrigeration systems in the automotive, appliance and commercial construction industries.
