Torre quadrada GFNL₂ de contracorrente com estrutura de aço

Especificação

Tower type	Square counter-flow, steel frame, FRP enclosure, large single cell
Typical cell duty	GFNL₂-2000: 2,000 m³/h · 42 / 32 °C · wet bulb 28 °C · range 10 °C
Fan	Kinetic-energy-recovery cylinder, Φ850 mm on the 2,000 cell
Motor	75 kW on the GFNL₂-2000 example; VFD drive for part load
Reducer	Horizontal gear reducer with oil-temperature and vibration alarm
Noise	≤ 75 dB(A) at the standard measuring point
Frame	Hot-dip galvanised steel structure, anti-corrosion treated
Enclosure	FRP panels — light, corrosion resistant, UV stabilised
Arrangement	Multi-cell modular for capacities above one cell

Notas de projeto

• 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.
