Trane has introduced the RTSF HT, a high-temperature water-to-water heat pump capable of delivering hot water up to 110°C. The RTSF HT expands the Trane CITY™ portfolio of compact water-to-water heat-pumps and chillers. Designed to meet the demands of industrial and commercial applications, the RTSF HT marks a significant step forward in decarbonising high-temperature process heating, which still heavily relies on fossil fuel boiler technology.

The RTSF HT is powered by Trane’s proprietary screw compressor technology and features ultra-low global warming potential (GWP) R1233zd(E) refrigerant. This combination ensures outstanding performance, achieving a coefficient of performance (COP) of up to 4.6 under typical operating conditions. The unit's compact footprint, just 930 mm wide, makes it ideal for applications requiring high capacity (up to 380 kW) while optimising space efficiency and reducing installation costs.

Equipped with the Trane Tracer Symbio 800 controller, the RTSF HT ensures smooth, reliable operation and connectivity through advanced algorithms, delivering operational efficiency with a low cost of ownership.

The RTSF HT is suited for a variety of applications, including industrial processes in food and beverage, pharmaceutical, and chemical sectors, as well as district heating and cooling and advanced cascade heating systems. The system’s ability to recover industrial waste heat enables customers to optimise energy use and reduce the carbon footprint of the industrial thermal system, contributing to the sustainability of their operations.

The RTSF HT product introduction aligns with Trane's and Trane Technologies' commitment to sustainable innovation. Providing sustainable cooling and heating solutions is part of Trane Technologies’ overall approach to reducing carbon emissions in the industries and markets they serve. It helps advance the 2030 Sustainability Commitments, including the Gigaton Challenge to reduce customer greenhouse gas emissions by 1 billion metric tons.

We are looking forward to meeting with you at our stand and show you our newest applications.
