R-448a Honeywell Solstice gas is a highly energy-efficient, non-flammable HFO-based refrigerant blend. Designed as an eco-friendly replacement for R-404A and R-22 in commercial refrigeration, it lowers Global Warming Potential (GWP) by roughly 65% while providing 5-10% better energy efficiency than R-404A.

Core Features

• Composition: A zeotropic blend consisting of R-32 (26%), R-125 (26%), R-134a (21%), R-1234ze(E) (7%), and R-1234yf (20%).
• GWP Rating: 1,273 (significantly lower than legacy HFCs).
• Safety: ASHRAE A1 safety classification (non-flammable and non-toxic).
• Oil Compatibility: Requires Polyol Ester (POE) lubricant.

Primary Applications

• Supermarket Systems: Used extensively in display cases and walk-in freezers.
• Industrial & Commercial Refrigeration: Ideal for low- and medium-temperature Direct Expansion (DX) refrigeration systems.

Retrofitting Capabilities

Solstice N40 serves as a close, direct drop-in replacement for legacy refrigerants, often avoiding the need for costly compressor replacements. It is widely used to retrofit systems previously running on:

• R-404A
• R-507
• R-407A and R-407F
• R-22
