FLEX N HP Air-to-Water Heat Pump
Cooling capacity: 62 - 125 kW
Heating capacity: 48 - 98 kW
- Extended operating map: hot water up to 77°C and continuous operation even in cold climates, down to -20°C.
- Inverter scroll compressors and EC fans: precise, efficient performance across variable loads.
- 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 Symbio 800 controller providing advanced cybersecurity features.
- Quiet operation: 4 noise level versions to suit even the most noise-sensitive applications.
Built to perform in every climate
Hot water production up to 77°C, FLEX N HP operates reliably in demanding climates with continuous performance down to –20°C and up to 45°C ambient, making it ideal for both new installations and boiler-replacement retrofits.
Efficiency that sets a new benchmark
Delivers top‑tier seasonal efficiency in both heating and cooling, with SCOP values up to 4.5, powered by full inverter scroll technology and the thermodynamic strength of R290 to ensure low operating costs and sustainable performance.
Modular platform engineered for growth
Built on a fully modular platform, FLEX N HP allows fast hydraulic connection and streamlined electronic control in banks of up to six units, delivering heating 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.
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 HP is a modular air-sourced heat pump designed with full inverter scroll technology, available in 4 sizes. Its modular architecture supportis heating capacities that extend beyond 700 kW.
