ISCEON® MO79 is an easy-to-use, non-ozone-depleting HFC refrigerant for replacing R-22, R-502 and HCFC containing refrigerant blends in medium- and low temperature commercial and industrial direct expansion refrigeration systems.

» ISCEON® MO79 Case Histories

ASHRAE #

R-422A

Replaces

R-22, R-502, HCFC-containing blends

Applications

• Medium- and low-temperature commercial and industrial direct expansion refrigeration, including, food service, supermarket display cases, food storage and processing and ice machines.

Benefits

•  Provides easy, quick, cost-effective retrofits
• Non-ozone-depleting HFC
• In most cases, no change of lubricant type during retrofit is required— compatible with traditional and new lubricants
• Enables the continued use of existing equipment
• 20% lower Global Warming Potential (GWP) vs. R-404A and R-507
• Can be topped off during service without removing entire refrigerant charge

Performance

• Provides improved cooling capacity over R-22 at many operating conditions with up to +15% at low temperature conditions
• Provides comparable cooling capacity to R-404A
• Field testing shows it can provide improved energy efficiency vs. R-22
• Significantly lower discharge temperature vs. R-22—likely to prolong the life of the compressor

Lubricant Recommendation

ISCEON MO79 is compatible with traditional and new lubricants, including mineral oil, alkylbenzene and polyol ester. In most cases, no change of lubricant type during retrofit is needed. See the ISCEON® MO79 Retrofit Guidelines for details.
