By Emiliano Bellini 22 Sep 2026 Technology & Products Commercial & industrial Heat pumps The WeatherFlex 50FC heat pump | Image: Carrier Advertisement Carrier, a US-based heating solutions provider, has launched a new reversible rooftop heat pump for commercial and industrial buildings. The WeatherFlex 50FC is an air-to-air unit using R-454C, an A2L refrigerant with a global warming potential (GWP) below 150.

How it works

• Carrier said the product was developed in anticipation of tighter requirements under the European Union's F-gas rules for commercial heat pumps and air-conditioning equipment.
• Available configurations include free cooling, heat recovery, variable ventilation and extended airflow.
• Factory-programmed controls are intended to reduce commissioning requirements during installation.
• Carrier has also equipped the units with integrated controls for multi-zone management and energy metering.
• They can be connected to the company's Abound HVAC platform for remote monitoring and building-system management.

What to take from it

The manufacturer said the new range targets commercial applications affected by the next stages of the EU F-gas phase-down.
