OUR TECHNICAL SCOPE (continuously evolving)

 

We are perfectly qualified to deliver following HVLS-fan technical scope:

Introduction :

This is our latest development.

It is truly a forgotten treasure, especially for very large, high ceiling buildings.

This very large, slow-spinning axial ceiling-fan has a proven, very beneficial effect on the following 3 parameters, important to our lives, all over the world:

  • Comfort
  • Energy-consumption (short investment pay-back time)
  • Hygiene

General technical overview:

  • HVLS-fan series: Check one of our 3 series below
  • Number of blades / impeller:  → 4, 5 or 8
  • Diameter-range (m / ft):   → 3,7m / 12ft, 4,9m / 16ft, 6,1m / 20ft, 7,1m / 23ft
  • Rotation speed range (Rpm):  → 50 to 90
  • Max. surface-reach (m² / ft²):  → 1500 m² / 16145 ft² to 2000 m² / 21528 ft²
  • Max. diameter-reach (m / ft): → 44 m / 144 ft to 50 m / 164 ft
  • Motor Power range (kW / HP): → 1,1 kW / 1,5 HP & 1,5 kW / 2 HP
  • Input Voltage range (V) @ Frequency (Hz):
  • Noise pressure levels:  → Less than 40 dB(A)

Construction features:

  • Moto-reducer from Germany, make SEW or SIEMENS
  • Control-box with inverter from France, make SCHNEIDER
  • Extruded aerofoil-blades in high strength aluminium alloy featuring:
  • 2 sets of internal stiffener-systems
  • Additional steel wire grooves (patented “fracture-dropping system”)
  •  Impeller-hub in high strength aluminium alloy ZL 114
  • Motor-reducer connection-parts in CNC-processed 45# steel-forgings
  • “Petioles” (connection-parts between hub and each blade) in high strength extruded rod of magnesium-alloy 5A06 (> 400 MP tensile strength)
  • 6 mm. thick, continuously welded supporting frame in Q345 steel sheet
  • High quality spray surface-treatment of all carbon steel surfaces
  • Unique security-measures featuring:
  • Secure ring connection, interconnecting all blades to form one whole
  • Traction-devices involving 4 steel wires, each with stress-intensity of 1000 kg
  • Patented “fracture-dropping system”, involving 2 steel wires braided inside each blade
