Trane unveils low-GWP R1234ze heat pump

Global HVAC innovator Trane has released its City RTSF range of water-to-water heat pumps, offering a low global warming potential (GWP) solution that performs efficiently at capacities below 400kW.

According to Trane, the City RTSF range of heat pumps is:

• Ideal for boiler replacement, heating water up to 80°C when used as a booster in cascade with an air-to-water Trane CXAF or RTXC heat pump, and/or CMAF or RTMG multi-pipe heat pump
• Fully optimised for HFO R1234ze (<1 GWP) or R515B as an alternative
• Designed to require minimal quantities of refrigerant, thanks to its stainless steel plate heat exchangers
• Reliable, thanks to the Trane screw compressor with Adaptive Frequency Drive coming as a standard feature.
• Compact and modular, fitting in restricted spaces (920mm width), making these heat pumps an appropriate modular HFO solution for applications with limited access or tight spaces.

Trane will be showcasing the City RTSF range at stand 758-759 during ARBS 2024.
