When it comes to reliable refrigeration in commercial and industrial systems, the choice of refrigerant plays a crucial role in performance, efficiency, and regulatory compliance. Among the latest and most widely adopted refrigerant innovations is R448A – specifically the R448A 25lb Cylinder Honeywell Solstice N40 Made in USA. Designed for both new equipment and retrofits, this refrigerant is leading the way in energy efficiency and sustainability.

In this article, we’ll explore everything you need to know about this refrigerant — its composition, benefits, applications, environmental performance, and why purchasing it from Royal Refrigerants is the right move for HVAC contractors and business owners alike.

What is R448A Honeywell Solstice N40?

R448A, sold under the brand name Solstice® N40 by Honeywell, is a non-ozone-depleting, low global warming potential (GWP) refrigerant blend designed to replace legacy refrigerants such as R-404A and R-507A. These older refrigerants are high-GWP and contribute heavily to climate change.

The R448A blend includes:

☛ R-32
☛ R-125
☛ R-134a
☛ R-1234ze(E)
☛ R-1234yf

These components combine to deliver superior cooling efficiency while dramatically reducing environmental impact.

Why Choose R448A 25lb Cylinder Honeywell Solstice N40 Made in USA?

Here’s why this refrigerant has become the first choice for many commercial refrigeration experts:

1. Superior Energy Efficiency

Compared to R-404A, R448A offers up to 10% energy savings. This results in significant operational cost reductions over time, making it ideal for businesses that rely on consistent refrigeration, such as grocery stores, warehouses, and restaurants.

2. Low Global Warming Potential

With a GWP of around 1273, R448A dramatically reduces the carbon footprint of refrigeration systems, helping companies meet strict environmental guidelines and green building certifications.

3. OEM Approved & SNAP Listed

The EPA SNAP program lists R448A as an approved replacement for high-GWP refrigerants in commercial and industrial refrigeration. Additionally, many OEMs now support R448A for new installations and retrofit conversions.

4. Non-Ozone Depleting

R448A contains zero ozone-depleting substances, supporting long-term environmental sustainability and compliance with international agreements like the Montreal Protocol.

5. American-Made Quality

The R448A 25lb Cylinder Honeywell Solstice N40 Made in USA ensures superior quality control, consistent performance, and faster delivery when purchased domestically through trusted suppliers like Royal Refrigerants.
