Modular and scalable

FLEX2O CXWF heat pumps are suitable for almost any medium to large-sized commercial building or process cooling application to provide outstanding year-round efficiency.

Historic city centers and older buildings do not always allow for easy transportation of units into, onto or next to buildings. FLEX2O units have been specially designed for restricted spaces and to facilitate internal transport and easy installation. The modular and compact design is ideal when capacity extension is required as building demand or industrial process cooling or heating demand evolves.

High energy performance

CXWF heat pumps are sustainable, electrified alternative to traditional fossil-fueled boilers.

All CXWF heat pumps pass the high seasonal energy efficiency thresholds (SCOP) as defined in the applicable EU Ecodesign regulation.

Superior (seasonal) energy performance means:
• Low annual operating costs due to low electricity usage
• Sustainable HVAC system with low carbon emissions
• Access to national heat pump subsidy or fiscal grant schemes

Large operating maps

Large cooling and heating operating maps address specific design criteria of applications such as hospitals, office buildings, larger apartment buildings, warehouses and many industrial applications:
• Leaving chilled water temperatures between -7°C and 25°C
• Leaving hot water temperature between 20°C and 60°C

Geothermal applications

The technologies built into Trane’s Flex2O heat
pumps make them ideally suited to geothermal

  • FLEX2O - CXWF heat pumps are available in nine different capacities, with features that can be optimized to suit your building’s size and function.
    Your Trane Sales Engineer will help you select the ideal CXWF heat pump based on your specific performance criteria and available technical room space.
