Chian HVLS large industrial ceiling fan with Permanent magnet direct drive motor, Energy saving, low noise, soft wind, maintenance-free!
Industrial Ceiling Fan Performance Index
1. Permanent magnet synchronous motor, permanent magnet synchronous motor can be installed on the wheel shaft as a whole, forming an overall direct drive system, that is, a wheel shaft is a drive unit, eliminating a gear box, completely sealed, truly maintenance-free.
2.Large air volume coverage range, the use of aerodynamic principles and advanced technology streamlined ultra-long fan blade, to transport a large amount of air, so as to form a 3-10ft air layer on the ground, bringing large air volume coverage
3.High efficiency motor, The HVLS fan has an efficiency of 84% within the Speed range, especially under 70% of the highest speed load the motor efficiency can be achieved 90%;
4.The use of air conditioning with fans can save electricity by more than 30%, and indoor air circulation is limited. The use of air conditioning with industrial fans can accelerate the cooling effect of indoor air flow, reduce the running time of air conditioning units, and greatly save electricity.
5.Servo drive controller, with frequency control system, speed 20-65rpm, just need to rotate the speed control button, can meet the requirements of different wind conditions.
6.Special design of motor temperature controls ,when fan Motor temperature controlling, once the motor temp are higher than the set data, controller will slow down the motor speed automative, when it cool down, it will go back the set speed.
Large ceiling fans customized for your needs. Say goodbye to high energy costs and poor air quality.
Cool Employees
HVLS fan generated by the natural breeze blowing on the human body, promote the evaporation of sweat to take away heat, and make the human body cool down, bring cooling feeling. Usually, this cooling sen sation can reach by 8°F
Increase Productivity
Worker productivity drops when people become unfcomfortably hot. Airflow maximizes the body's natural means of cooling. It will achieve a healthy, comfortable and safe working environment.
Savings
Large High volume low speed ceiling fans provide a notable monetary savings over air-conditioned spaces.
HVLS Fan Motor
PMSM can be installed on the wheel shaft as a whole, forming an overall direct drive system, that is, a wheel shaft is a drive unit, eliminating a gearbox, completely sealed, and truly maintenance-free.
HVLS Fan Controller
Servo controller, using an advanced full digital motor control algorithm, built-in over voltage, over current, overload, and short circuit protection, can read the real-time fan motor temperature and control the motor running in a safe temperature range.
Safety Design
Adopt more than 10 safety protection measures (safety rope, safety ring, anti-drop bushing technology, type I fan blade link, top 12.9-grade fastener, anti-loose fastener, fan blade strengthening design, enhanced plug-in design, overload protection of control system, etc.)

Application of HVLS fan
Which places are most suitable for installing HVLS fans?
Large workshop
Large workshops such as machinery processing plants, auto repair plants, aircraft assembly plants, and shipyards all use this fan.
Large logistics warehouse distribution center
For logistics storage workshops, air quality can be improved, dehumidification and dehumidification can be prevented, and rust and decay of warehouse goods.
Business occasion
Large-scale industrial fans are also widely used in various commercial occasions, As long as it is a large and high space occasion, industrial fans (commercial fans) will be hung, such as railway stations and bus stations, airports, military units, churches, stadiums, shopping malls, etc.
Large farm
Large industrial fans are also widely used in large farms, including dairy farms, feedlots and hatcheries. Good ventilation can improve air quality, dehumidify and deodorize, and reduce the incidence of livestock.

Remark
Regarding the noise test: under the condition that the rotation plane of the fan blade is> 8 meters from the ground and the rotation plane of the fan blade is> 2.5 meters from the roof, the vertical distance of the vertical line of the fan is 7 meters, and the sampling is carried out at a plurality of circumferentially distributed positions at a height of 1.7 meters on the ground Obtained reference noise data (the geometry of the roof and whether there are pillars around it will affect the noise test)
About comfort index characteristics
1. The fan produces wind speeds between 0.6m/s-2m/s
2. The ambient temperature is between 20 and 33℃
3. The relative humidity of the environment is between 50% and 85%
