ASHRAE

R-417A; A1 Safety Classification

Replaces

R-22

Applications

Residential and commercial AC systems
Note: For water chillers ISCEON® MO29™ is recommended
Medium-temperature commercial refrigeration, including:
food service
supermarket display cases
food storage and processing

Benefits

Provides efficient, 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 continued use of existing equipment
Can be topped off during service without removing the entire refrigerant charge

Performance

Significantly lower discharge temperature and pressure vs. R-22; likely to prolong the life of the compressor
In most systems provides required cooling capacity
Has been shown to offer energy savings in some systems

Phaseout Schedule
ISCEON® MO59 is a zero ozone-depleting substance ( ODS) and, therefore, is not subject to phaseout under the Montreal Protocol regulations.

Lubricant Recommendation
ISCEON® MO59 is compatible with traditional and new lubricants--mineral oil ( MO) , alkylbenzene ( AB) , and polyol ester ( POE) --in most cases, no change of lubricant type during retrofit is required. Refer to the ISCEON® MO59 Retrofit Guidelines for more details.
