R449A REFRIGERANT GAS
25 LB (11.3 KG) CYLINDER
High-performance, lower-GWP refrigerant for
commercial and industrial refrigeration systems.
Professional Cooling Performance
R449A is a zeotropic HFO/HFC refrigerant blend designed
for low- and medium-temperature refrigeration applications.
It is commonly selected as a lower-global-warming-potential
alternative to R404A and R507 refrigerants.
R449A can be used in approved new equipment and in
suitably converted refrigeration systems. It is frequently
used in supermarkets, commercial refrigeration units,
cold storage facilities, food processing operations,
and industrial cooling applications.
With zero ozone depletion potential, ASHRAE A1 safety
classification, and a significantly lower GWP than R404A,
R449A provides an established option for compatible
commercial refrigeration equipment.

secure storage and professional handling when provided
by the supplier.
Professional Refrigeration Applications
R449A is suitable for approved refrigeration equipment
that requires this specific refrigerant.
03 / Recommended Applications
01 — Commercial Refrigeration
Designed for compatible commercial refrigeration equipment
including supermarket display cases, refrigerated cabinets,
walk-in coolers and freezers.
02 — Equipment Retrofit
R449A is commonly used in appropriately converted R404A
and R507 refrigeration systems. Retrofit work must follow
equipment manufacturer and refrigerant supplier guidance.
03 — Food Processing
Suitable for approved food processing refrigeration
systems requiring controlled low- and medium-temperature
operation.
04 — Cold Chain Storage
Used in compatible cold rooms, refrigerated warehouses
and temperature-controlled storage facilities.
05 — Industrial Refrigeration
Applicable to approved industrial direct-expansion
refrigeration systems and other compatible installations.
04 / Professional Refrigeration Use
R449A is frequently selected by refrigeration professionals
for compatible new equipment and properly planned retrofits
of existing R404A or R507 systems.
Technicians should verify refrigeration system compatibility,
lubricant requirements, operating pressures, expansion
devices, temperature glide and manufacturer recommendations.
As a zeotropic blend, R449A should generally be charged
from the cylinder in its liquid phase, using proper methods
to avoid compressor damage and maintain the intended
refrigerant composition.
It is not a universal drop-in replacement. Conversion
may require system adjustments and must be carried out
by appropriately qualified technicians.
Safety & EPA Compliance
R449A has an ASHRAE A1 safety classification, but it is
still a pressurized refrigerant that requires controlled
handling, safe storage and proper servicing procedures.
- Use only in compatible approved refrigeration equipment.
- Keep cylinders in cool, dry, ventilated areas.
- Secure cylinders against tipping and physical damage.
- Avoid excessive heat and high temperatures.
- Follow the manufacturer's Safety Data Sheet.
- Use suitable refrigerant recovery and charging equipment.
- Do not intentionally release refrigerant into the atmosphere.
- Follow applicable EPA and local regulations.
Purchaser Notice: Buyers must meet applicable EPA
refrigerant purchasing requirements, including technician
certification or permitted resale conditions.
