Opteon™ XP10 is an azeotropic refrigerant offering
excellent capacity and efficiency match for R-134a in new
systems, as well as for retrofit of existing systems.

Uses

Opteon™ XP40 (R-449A)

The refrigerants that make up the Opteon™ XP series are all• Applications

safe and nonflammable (ASHRAE A1 Safety classification).

– Low- and medium-temperature commercial andThey have been approved for use as refrigerants by majorindustrial DX refrigerationequipment and component manufacturers and extensively– Supermarkets: centralized racks, distributed systems,

field tested, as well as are compatible with existing

walk-in coolers/freezers

equipment designs and lubricants. These existing
equipment designs include systems running R-134a, R-22,– Food service and cold storage

R-404A/R-507, and R-407 series refrigerants. Like other– Self-contained systems

refrigerant blends, Opteon™ XP10, XP40, and XP44 can betopped off after leaks.

• Benefits– Low GWP: 65% reduction compared to

Opteon™ XP10 (R-513A)

R-404A/R-507• Applications– Alternative to R-407 series low-/medium-– Medium-temperature circuit of hybrid cascade

temperature (equivalent capacity)

systems– 8-12% lower energy consumption– Medium-temperature commercial and industrial
DX refrigeration

Opteon™ XP44 (R-452A)– Water chillers, AC, heat pumps• Applications• Benefits– Low- and medium-temperature commercial andindustrial DX refrigeration– Low GWP: 56% compared to R-134a– Low- and medium-temperature transport DX– Excellent capacity and energy efficiency match

refrigeration– Close performance match, retrofit and new systems• Benefits– Azeotrope with zero glide– Low GWP: 45% reduction compared toR-404A/R-507– Matches discharge temperature– Matches mass flow rate (no TXV adjustments)
