A new refrigerant option for R-1234yf, known as R-444A, is now available for automotive professional use. R-444A has been thoroughly vetted for over a decade and is under consideration for first fill by leading vehicle manufacturers worldwide.

As an economical refrigerant option for R-1234yf for after market vehicle service providers, R-444A provides a boost to A/C system cooling performance and is more energy efficient.
Why should R-444A be considered over R-1234yf?

There are four primary reasons for this:
1. Performance: R-444A will cool a vehicle up to four minutes faster than R123yf.

2. Energy efficiency: R-444A consumes less energy during a typical driving cycle, offering an advantage to improve a vehicle’s fuel (ICE) or battery (EV) range.

3. Cost: R-1234yf is both more expensive to produce and under patent protection.
Both drive prices higher. In contrast, R-444A is made from common and “public domain” refrigerants for **lower relative cost.

4. Reliability: R-444A has no known conditions under which it can polymerize. It has also been fully tested for compatibility with system components and oils.

Amid the evolving landscape of vehicle thermal management systems and of regulatory pressure, it is worth noting that R-444A meets the low GWP100 <150 requirements with a CO2 equivalence of 93. In terms of PFAS (poly-fluoroalkyl substances), R-444A breaks down into substantially less TFA (trifluoroacetic acid) than R-1234yf during decomposition, making it an environmentally safe choice.

What is R-444a?

R-444A combines R-1234ze (83 percent), R-152a (5 percent), and R32 (12 percent) to create an azeotropic blend with a 7K glide.
Glide is the difference between the lowest and highest refrigerant component boiling points.
R-1234ze is the base contributing to its low GWP, while R-32 packs a performance punch and enhances the capacity that drives its excellent cooling performance.
