July 01, 2024

New lineup of products improves sustainability with R-454B refrigerant

SUWANEE, Ga. – June 25, 2024 – Mitsubishi Electric Trane HVAC US LLC (METUS), a leading supplier of Ductless and Ducted Mini-split and Variable Refrigerant Flow (VRF) heat pump and air-conditioning systems, announces its upcoming launch of a new line of products utilizing a low global warming potential (GWP) refrigerant, marking a significant step forward in environmental sustainability in light commercial and residential heating and air-conditioning solutions. The new products are anticipated to be available in early 2025.

The innovative product line, designed for both light commercial and residential applications, not only meets but exceeds current regulatory requirements without compromising performance.

The new products feature R-454B, a next-generation refrigerant with a GWP that is nearly 78% lower than R-410A. METUS is committed to developing products that utilize low-GWP refrigerants to uphold the company’s values of environmental stewardship and align with global efforts to phase-down high-GWP refrigerants as mandated by the American Innovation and Manufacturing (AIM) Act. Starting Jan. 1, 2025, A2L refrigerants such as R-454B will be the new industry standard.

“Our new A2L products are engineered to provide efficiency and reliability,” said Mark Kuntz, CEO of METUS. ”The all-climate, all-electric heat-pump technologies we offer are inherently low-carbon solutions, and the introduction of these new refrigerants makes them even more sustainable. This transition ushers in significant technological advancements, including some models having improved cold climate heating performance, enhanced safety features, advanced sensors or improved internet connectivity.”

In addition to environmental benefits, Mitsubishi Electric’s new systems are equipped with advanced safety features tailored to handle A2L refrigerants. Many of Mitsubishi Electric’s new systems feature safety features such as built-in leak detection sensors, shut-off valves and smart control logic, promoting safe operation and ease of installation.
