R448A REFRIGERANT GAS
25 LB (11.3 KG) CYLINDER
High-performance, reduced-GWP refrigerant for compatible commercial and industrial refrigeration systems.
Professional Cooling Performance
R448A, also known commercially as Solstice N40, is a nonflammable zeotropic HFO/HFC refrigerant blend designed for low- and medium-temperature commercial refrigeration applications.
R448A offers a lower global warming potential compared with R404A while supporting efficient performance in approved refrigeration equipment. It is commonly used in supermarkets, refrigerated display cases, cold storage warehouses, commercial freezers, and approved refrigeration retrofits.
With zero ozone depletion potential and an ASHRAE A1 safety classification, R448A is an established refrigerant for compatible professional refrigeration systems.

03 / Recommended Applications
01 — Commercial Refrigeration
For compatible supermarket refrigeration systems, refrigerated display cases, commercial freezers and walk-in coolers.
02 — Cold Chain Logistics
Used in approved refrigeration systems supporting temperature-controlled storage and distribution of perishable goods.
03 — Industrial Cooling Systems
Suitable for certain compatible industrial direct-expansion refrigeration equipment operating at low and medium temperatures.
04 — Refrigeration Retrofits
R448A can replace R404A or R507 in many compatible systems following a properly planned conversion and manufacturer-approved retrofit procedure.
05 — Food Storage & Processing
Used in suitable refrigerated warehouses, cold rooms and food-processing refrigeration systems.
04 / Professional Refrigeration Use
R448A is designed for compatible low- and medium-temperature commercial refrigeration systems. It may be used in approved new installations or properly converted existing equipment.
Professional technicians should confirm system compatibility, lubricant requirements, compressor discharge temperature, operating pressure, expansion devices and refrigerant temperature glide.
As a zeotropic refrigerant blend, R448A should generally be charged in the liquid phase using approved procedures to maintain its intended composition.
R448A must not be treated as a universal drop-in replacement. Retrofitting requires technical evaluation and may require equipment adjustments.
Safety & EPA Compliance
R448A is classified as ASHRAE A1, indicating lower toxicity and no flame propagation under specified test conditions. Pressurized refrigerant cylinders still require proper handling and storage.
- Use only in compatible approved refrigeration equipment.
- Store cylinders in a cool, dry and ventilated location.
- Keep cylinders away from excessive heat.
- Secure cylinders against tipping and physical damage.
- Follow the Safety Data Sheet and cylinder instructions.
- Use suitable recovery and charging equipment.
- Never intentionally vent refrigerant to the atmosphere.
- Comply with applicable EPA, federal, state and local regulations.
Purchaser Notice: Purchasers must satisfy applicable refrigerant sales requirements, including EPA technician certification or qualifying resale conditions.
