The RTSF HT, an addition to the Trane City portfolio of compact water-to-water heat pumps, is designed to meet the demands of industrial and commercial applications.
“The new City RTSF HT units extend our decarbonisation efforts into industrial process heating, complementing our portfolio of solutions for space and comfort heating,” said Erik van Oossanen, product management leader for Trane in Europe, Middle East and Africa. “Many industries heat and cool within the same process, often simultaneously. This practice causes large thermal inefficiencies. By electrifying process heating and enabling the repurposing of wasted thermal energy, we are helping industries transition away from fossil fuels and achieve ambitious sustainability targets.”
The RTSF HT is powered by Trane’s proprietary screw compressor technology and features ultra-low global warming potential (GWP) R1233zd(E) refrigerant.
According to Trane, 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 is claimed to ensure 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 is expected to enable customers to optimise energy use and reduce the carbon footprint of the industrial thermal system.
