Refrigerant Retrofit

  • For chillers from 200 to 1400 kW
  • Replacement of HFC refrigerants (such as R134a or R404A) with low GWP refrigerant R513A
  • Only 3% cooling capacity reduction
  • 50% reduction of chiller carbon footprint
  • Environmental protection

Future-proof, reduce carbon footprint and protect your investment

With F-Gas regulation, HFCs are gradually reduced – which has a huge impact on the availability and price of high Global Warming Potentia (GWP) refrigerants such as R134a. It has become vital for the industry and operators to make a timely transition to high efficiency refrigerants with a lower GWP – such as R1234ze, R1233zd, R513A, and R454B. Trane has developed a range of retrofit solutions suitable for current and earlier chiller models.

Chiller carbon footprint is directly linked to the refrigerant type used. For a refrigerant quantity between 60kg and 400kg, a refrigerant retrofit can represents a carbon footprint reduction of 44 tons to 325 tons of CO2.

Trane expertise with next generation refrigerants

Trane is dedicated to reducing the energy intensity of the world. As part of our Corporate Climate Commitment, we offer high efficiency products with next generation, low to ultra-low GWP refrigerants. As a major compressor manufacturer, we have decades of experience in equipment development and component qualification. We will ensure that all parameters have been taken into account when qualifying a next generation refrigerant.

Trane is extensively testing how our compressors perform with each refrigerant. Oil management is key to ensuring equipment operates trouble-free for years. Compressors are tested extensively under severe conditions to eliminate any risk of failure. Next generation refrigerants may require specific control algorithms to manage the oil return and work effectively with other different properties. Built-in heat exchangers must be compatible for operation with the new selected refrigerant and equipment performance maintained.

During a Trane Refrigerant Retrofit, a certified Trane technician follows a very strict process to ensure all actions are correctly performed. A Trane Refrigerant Retrofit will optimize your chiller to meet your current and future operational requirements.
