Solstice® HFO Blends

Solstice® 454A - (R-454A)

Solstice® 454A (R-454A) is a non-ozone-depleting, zeotropic blend designed as a low GWP alternative to R-404A in refrigeration applications.

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
