Torre quadrada de contracorrente DFN / GFN em PRFV

Name: Torre quadrada de contracorrente DFN / GFN em PRFV
Brand: SQR Holdings

Células quadradas modulares que se empilham até a capacidade que a planta realmente precisa.

As torres DFN e GFN são projetos melhorados a partir dos dados de ensaio do Instituto de Projeto e Pesquisa nº 4 do Ministério de Máquinas da China.

Especificação

Tower type	Square counter-flow, induced draft, FRP shell, modular multi-cell
Cell arrangement	Single-row or double-row multi-cell; add cells instead of oversizing one
Fan drive	Variable-frequency motor or low-noise permanent-magnet direct drive
Control	Temperature-sensor driven, real-time fan adjustment
Pipe direction	Inlet and outlet rotatable by 90°, 180°, 270°
Water basin	L — no basin · DP — shallow basin · GP — deep basin, 400 mm effective depth
Design conditions	Standard 5 °C range (D / CD) · industrial 10–25 °C (G type)
Inlet water	Up to 60 °C (higher on request)
Water quality	Circulating turbidity ≤ 50 mg/L, short term ≤ 100 mg/L
Cold resistance	−50 °C; anti-icing required below −10 °C monthly average

Cells, not one big towerA failed cell is isolated and the plant keeps running at reduced capacity; the same cell size covers a 20 % expansion without a new tower.
Direct drive where noise mattersThe permanent-magnet direct-drive option removes the belt and gearbox, cutting the dominant low-frequency noise and the maintenance interval with it.
Three basin depthsNo basin for pit installations, shallow basin for slab mounting, 400 mm deep basin where pump suction needs the volume.
Rotatable connectionsInlet and outlet can be turned 90°, 180° or 270° on site, which saves a header rework when the plant room layout changes.
