Trane has introduced FLEX N, a new range of modular full-inverter scroll air-cooled chillers for commercial buildings and manufacturing facilities. The units use non-ozone-depleting, ultra-low GWP R290 refrigerant and are designed for comfort and process cooling applications.
The FLEX N range delivers an average Seasonal Energy Efficiency Ratio of 5.4 in comfort cooling and an average Energy Performance Ratio – High Temperature of 5.9 in process cooling. The units can provide chilled water between 25° and -12°C (77°F and 10.4°F).
The modular design supports side-by-side installation of up to six units with minimal clearance, allowing total cooling capacity to scale up to 750 kW (approx. 2.56 million BTU/h). FLEX N is available in nominal cooling capacities from 64 to 125 kW (approx. 218,000 to 426,000 BTU/h) and in four acoustic versions.
Configuration options include integrated hydraulic modules, medium- and high-pressure pumps, bypass kit, protection panels, grilles, and metal mesh coil filters. The safety package includes an ATEX leak-management system, shared interlock shutdown, and an optional high-efficiency gas/water separator.
FLEX N integrates with building automation systems through the Trane Symbio 800 controller, a field-programmable platform supporting BACnet IP and Modbus TCP.
“With FLEX N, building and process owners gain a practical route to lower-carbon operations without compromising performance, flexibility or reliability — all within a single product platform,” said Erik Van Oossanen, Product Management Leader at Trane.
