The future of sustainable heating

At Trane, we believe in electrification of heating as an important global contributor to mitigate climate change and reduce carbon footprint. The Sintesis™ Advantage CXAF provides best-in-class efficiency levels at Eurovent Class A full load performance.
CXAF models comply with ErP 2021 efficiency thresholds, using the most innovative technology on the market.

CXAF uses ambient air as its heat source, resulting in a substantially lower carbon footprint and no emissions compared to fossil fuel boilers.

Flexible, reliable and simple

Trane CXAF heat pumps are built on Trane’s well-known Sintesis™ platform, which means they share many of the same components and technologies – all with a proven reliability record.

Tracer® Symbio™ 800 unit controller ensures smooth operation and reliable comfort for building users, while also allowing for easy maintenance, keeping costs to a minimum.

Improved performance at all operating conditions with Trane LESSS (patent pending)

The Trane Low Energy Super Subcooler system (LESSS) is a unique heat pump refrigerant system which makes intelligent usage of superheat generation and mass flow control to optimize the refrigerant charge under any operating conditions.

Fully designed and tested by Trane, the net capacity of the unit is increased by up to 7%, improving energy efficiency across all seasons. Trane LESSS also enhances system reliability by improving compressor lubrication and preventing liquid slugging.

Thanks to Trane’s most recent innovation, the unit efficiency is higher without needing to oversize the heat exchanger section. In short, you can do more with LESSS.

Low noise operation

With variable volume scroll compressors, variable speed fans and insulation options to reduce sound even further, CXAF heat pumps are the ideal choice to keep your building warm or cool - quietly and efficiently.

  • Model CXAF is available in two efficiency versions (SE and HE), which can be coupled with three low noise packages (SN, LN, XLN). You can also choose between AC, EC and EC Axitop fans to improve the efficiency of your system within budget.
