Marvair R-454B Transition

At Marvair, innovation and sustainability are at the heart of everything we do. We are thrilled to announce a significant milestone in our journey towards eco-consciousness: the transition to R-454B refrigerant across our product line.

R-454B is a next-generation, low-global warming potential refrigerant that aligns perfectly with our commitment to environmental responsibility (78% lower GWP then R410A). This transition represents our dedication to reducing carbon emissions and mitigating environmental impact while delivering exceptional performance and reliability.

In light of this transition, we want to inform you of some important dates regarding the availability of our products:

  • MAA/MGA Small Cabinet Air Conditioners and Heat Pumps:
    Last Date to Order: October 15, 2024
  • MGA/CFA Large Cabinet Air Conditioners:
    Last Date to Order: August 31, 2024

Please note that the last date of manufacture for units utilizing R-410A refrigerant will be December 31, 2024. After this date, all our products will exclusively feature the environmentally friendly R-454B refrigerant.

We understand the significance of this transition for our customers, and we are committed to ensuring a smooth and seamless experience throughout the process. Our dedicated team is available to assist with any inquiries or concerns you may have regarding this transition.

It is important to note that while A2L refrigerants like R-454B are considered mildly flammable, they are difficult to ignite and have a low flame speed. Therefore R-454B poses no significant risk for installers, service technicians or site operators.

  • A2L refrigerants are so mildly flammable that there must be a significant energy source, like a direct flame and a high concentration of refrigerant to be able to ignite.
  • If an A2L refrigerant were to ignite, the flame would be unsustainable.
  • An A2L refrigerant flame would spread at an extremely slow speed of less than half a mile per hour – slower than typical walking speed.
  • As an additional precaution, all Marvair air conditioners and heat pumps with R-454B are factory equipped with a leak detection system.

Thank you for your continued support as we embark on this journey towards a more sustainable future together. We look forward to serving you with our innovative and environmentally conscious products.
