Gas lạnh Dupont Isceon MO79

DuPont ISCEON MO79 is a cost-effective, 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.

Refer to Copeland's Changeover Guidelines, which now include R-22 to ISCEON MO29 (R-422D) and ISCEON MO79 (R-422A).

ASHRAE

R-422A; A1 safety classification

Replaces

R-22, R-502, and HCFC-containing blends (e.g., HP80, HP81, R-408A)

Applications

    Medium- and low-temperature commercial and industrial direct expansion refrigeration, including:

        food service

        supermarket display cases

        food storage and processing

        ice machines

Benefits

    Provides efficient, cost-effective retrofits--easier retrofit than R-404A and R-507

    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

    20% lower global warming potential (GWP) vs. R-404A and R-507

    Can be topped off during service without removing the entire refrigerant charge
