  • 99.5% reliability rate with screw compressor technology and Adaptive Frequency™ Drive as standard
  • Fully optimized for HFO R1234ze (<1 GWP)
  • Minimized refrigerant charge with stainless steel plate heat exchangers
  • Compact and modular, they particularly fit in restricted spaces. 920 mm width only
  • Ideal modular HFO solution for tight spaces
  • Heating up to 80°C; source temperature from -12C to +30C

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

Modern cities often present challenges when it comes to easy transportation of large units into, onto or next to buildings. The City has been specially engineered for restricted spaces, and easy installation.

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.

• 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.

• City Booster optimizes operation and efficiency to deliver hot water between 50°C and 80°C, with source temperatures from +5°C to +30°C. City Booster offers a unique opportunity to move to renewable energy heating.

Trane expertise and experience
