HVLS Industrial Fan

A high-volume low-speed (HVLS) fan is a type of mechanical fan greater than 7 feet (2.1 m) in diameter. HVLS fans are generally ceiling fans although some are pole mounted. HVLS fans move slowly and distribute large amounts of air at low rotational speed– hence the name "high volume, low speed". These fans have very low revolutions per minute as compared to other fans. But due to their large size, they can provide a high volume of air at low speed.

The size of these fans can vary from 2.8m (9ft) to 7.3m (24ft). This is their diameter from one tail to another. Moreover, they have a different aerodynamic design as well. The blades are not like normal fans, they have a special aerodynamic design. The number of blades is also more than normal fans. RTFANS all huge HVLS fans have six blades and a patented airfoil design for better strength and flexibility.

HVLS Fans Wind Chill Effect

The gentle breeze brings by RTFANS HVLS fans to our body can accelerate sweat evaporation and make people feeling cool, usually, this sensible temperature created by the wind chill effect can be 5-8℃, in addition, the gentle wind from all sides will make people more comfortable compared with a traditional powerful fan.

The running of a big diameter industrial fan blade accelerates the airflow and increases the evaporative efficiency of the sweat on a human being's body, and this evaporation process takes away heat in the body, that’s called wind chill effect. As for the specific influence created by different wind speeds, please see the above graph, which can show you different temperatures with different wind speeds to make the difference that people feeling.

NORD Drive System

German “Simrit” double oil seal design, durable and reliable.
“Shell” top class “Omala” S4 lubrication oil, zero maintenance for over 20000 hours.
low maintenance and long service life.
High efficiency for low operating costs.
Robust grey cast iron housing.
High axial and radial load capacities enable reliable operation.
Quiet running.

Variable-frequency Drive

Denmark “DANFOSS” frequency converter & German “Schneider” electrical sets.
The penetration of dust is minimized thanks to coated PCBs, the drive ensures reliable and cost-effective operation also in demanding environments.
Radio disturbance from motor cables is limited due to built-in RFI filters.
A lifetime of the drive is extended and reliability improved as a result of the effective heat sink that removes heat from the electronics.
Energy consumption can be reduced as kinetic energy in the application can be transformed into braking power to slow down the motor.
