GFNL₂ · 2,000 m³/h per cell
GFNL₂ Steel-Frame Square Counter-Flow Tower
Galvanised steel frame carrying FRP panels — large single-cell capacity with a structure you can inspect.
- Motor75 kW on the GFNL₂-2000 example; VFD drive for part load
GFNL₂ puts a hot-dip galvanised steel frame under the FRP enclosure. The frame takes the wind and seismic load, the FRP panels keep the water clean and the weight down, and the kinetic-energy-recovery fan cylinder recovers exit energy instead of wasting it. A horizontal gear reducer with oil-temperature and vibration alarms makes the drive condition visible before it becomes a shutdown. Typical published duty for the GFNL₂-2000 cell: 2,000 m³/h, 42 °C in, 32 °C out, 28 °C wet bulb, 10 °C range, Φ850 fan, 75 kW motor, ≤ 75 dB(A).

Design notes
- Structure you can walk onGalvanised columns and beams carry walkways and ladders without relying on the FRP shell for stiffness.
- Energy-recovery fan cylinderThe diffuser-shaped cylinder recovers exit kinetic energy, which shows up as lower shaft power for the same airflow.
- Drive condition on displayOil temperature and vibration alarms on the reducer turn an unplanned outage into a scheduled service call.
- Single cell, large capacityOne GFNL₂ cell covers the duty of several smaller FRP cells, which cuts plot area and interconnecting piping.
