R-22 Refrigerant… Increasing Cost and Reduced Supply Are Challenging Compressed Air System Operators

Since legislation has phased out the production of new equipment utilizing R-22 as a refrigerant, the price of R-22 has increased considerably. That trend will likely accelerate when production of new R-22 is banned in the US in 2020.

If you’re the operator of a compressed air system that includes a refrigerated dryer, consider these facts:

• Environmentally Friendly Refrigerants

Refrigerants being used today such as 404A and 134A are much more environmentally friendly. This may help you achieve your Green initiatives.

• Dryer Efficiency

Newer designs are generally more efficient than older models.

• Price Escalation

The service and repair costs for older dryers increase as the cost of R-22 goes up. The cost of refrigerant in a 1,000 SCFM, R-22 dryer can run $1,300. The price of R-22 is currently about 3X that of R-404A.

• Refrigerant Availability

After 2020, only reclaimed/recycled and stockpiled inventory of R-22 will be available for air dryer repairs.

• R-22 Component Availability

As R-22 refrigerant supply dwindles, so will availability of R-22-specific components like compressors, expansion valves, etc.

With a complete phase-out of R-22 on the horizon, now is the time to consider the future of compressed air systems that include older drying equipment.
