The Trane City RTSF water-cooled chiller is a high-performance, modular heat pump solution designed for demanding applications such as district heating and cooling. Engineered for efficiency and reliability, this unit features an impressive 99.5% reliability rate. With a slim profile measuring only 920 mm in width, it is specifically optimized for installation in restricted spaces, making it an ideal choice for capacity extension projects in urban environments like office buildings and universities. Sustainability is at the core of the City RTSF design. The units utilize advanced HFO refrigerants, specifically R1234ze, which offers a very low GWP (Global Warming Potential) of less than 1. The chiller is also compatible with R515B as an alternative option. Capable of reaching output temperatures up to 80°C, these heat pumps provide a flexible and environmentally conscious solution that helps reduce carbon footprints while lowering overall maintenance costs for large-scale energy systems.
