City™ RTSF Water-Cooled Chiller

Cooling capacity: 180 - 385 kW

  • 99.5% reliability rate
  • Compact and modular: Fits in restricted spaces - 920 mm width only
  • Fully optimized for HFO refrigerant R1234ze (<1 GWP)
  • Wide operating range: from -12°C to 30°C leaving temperature on the evaporator side and from 10°C to 80°C leaving temperature on the condenser side
  • Single screw compressor and Adaptive Frequency™ Drive

Sustainable and efficient

The City RTSF has been designed to reduce environmental impact. This is a low global warming potential solution with industry leading efficiencies for capacities below 400 kW.
The City RTSF features low GWP (<1) R1234ze and carries the EcoWise endorsement.

Compact and modular

Urban environments often make it hard to easily transport large units into, onto or next to buildings. The City has been specially engineered for restricted spaces, and ease of installation.

City’s modularity makes it suitable when an extension of capacity becomes required as the building evolves or when the chiller plant is designed with multiple staggered chillers to further improve efficiency.

Wide range of applications

The City chiller satisfies any application and covers a wide spectrum of operating conditions:

• City Comfort prioritizes performance and sustainability. Efficiency is optimized for moderate comfort applications in cooling or heating up to 50°C, or industrial process applications at positive temperatures, with source temperatures from +5°C to +30°C.

• City Process is a highly sustainable solution (GWP < 1) with safe operation. Efficiency has been optimized for freezing industrial brine process applications. City Process delivers hot water between 10°C and 80°C, with source temperatures from -12°C to +5°C.

Trane expertise and experience

Trane's industry-leading compressor offers direct drive, low speed screw AFD driven for premier efficiency, perfect load matching and unequalled long- lasting reliability.

  • Operating Conditions: Comfort and Process cooling ‒ From -12 to 30°C on the evaporator side and up to +80°C on the condenser side

  • City chillers are available in six different cooling capacities with many options and accessories such as the sound attenuation panels (up to -9 dB(A) attenuation)
