Overview
Solstice® 454A (R-454A) is a non-ozone-depleting, zeotropic blend designed as a low GWP alternative to R-404A in refrigeration applications. Solstice® 454A demonstrates approximately 6% improved efficiency, 8% better capacity and has 94% lower GWP than R-404A.
With its environmental qualities and an evaporator glide of ~8oF, R-454A can be an effective long-term refrigeration solution in many applications:
• Low and medium-temperature supermarket refrigeration systems
• Retail food condensing units
• Cold storage
• Industrial Process Refrigeration (non-chiller)
• Industrial Process Refrigeration (chillers)
*Maximum 200lb in applications per EPA Technology Transitions Rule
