Flex N Air-Cooled Chiller
Cooling capacity: 64 - 125 kW





- Inverter scroll compressors and EC fans: precise, efficient performance across variable loads.
- Extended operating map on both operating ambient temperature (-20°C to 46°C) and leaving water temperature (-12°C to +25°C) makes the unit suitable for a wide range of applications
- Modular design supports quick hydraulic connection and simplified controls for up to 6 units.
- Compact footprint and side-by-side installation with minimum clearance.
- Proprietary Tracer Symbio 800 controller providing advanced cybersecurity features.
- Quiet operation: 4 noise level versions to suit even the most noise-sensitive applications.
- Completely integrated hydraulic kit with buffer tank and pumps
- Partial heat recovery
Efficiency that sets a new benchmark
Delivers top‑tier seasonal efficiency in both comfort cooling and process cooling applications, powered by full inverter scroll technology and the thermodynamic strength of R290 to ensure low operating costs and sustainable performance.
Comfort Cooling: SEER up to 5.4.
Process Applications: SEPR HT up to 5.9.
Modular platform engineered for growth
Built on a fully modular platform, Flex N allows fast hydraulic connection and streamlined electronic control in banks of up to six units, delivering cooling capacity up to 750 kW. The compact, easy‑to‑transport design simplifies installation and enables capacity to be added over time as building requirements evolve. Its side‑by‑side configuration minimizes site space, while the low refrigerant charge per circuit enhances both safety and environmental responsibility.
Wide operating limits
Flex N air-cooled chillers are designed for efficient year-round operation in both cold and hot climates. They can be configured to operate at full load within a wide outdoor air temperature range, from -20°C to +46°C.
With a leaving water temperature range from -12°C to +25°C, these chillers are ideal for a variety of applications, from comfort cooling to the most demanding process cooling needs.
Safety-forward design
Features a comprehensive safety pack based on Trane’s SDS2E approach (Segregate, Detect, Stop, Signal, and Extract), including ATEX‑certified leak management and safety relief valves. The optional integrated gas/water separator offers a unique solution by detecting and isolating leaks in the event of a BPHE failure. In parallel, the interlock system enhances protection in side‑by‑side modular installations.
Flex N is a modular air-to-water chiller designed with full inverter scroll technology, available in 4 sizes. Its modular architecture supportis heating capacities that extend beyond 700 kW.
