7.3m 24FT Large Industrial Ventilation and Cooling Hvls Fan From China Factory

Product description

The wind blown from large industrial ceiling fan feels like natural breeze system,the wind speed is just the best cool feeling of human skin. Personnel can feel the temperature difference 5-8 degree, provide personnel a suitable working environment in hot summer,therefore improve the production efficiency.
Function of the fan:
1)ventilation
The fan improve air exchange in an entire space, it's perfect streamlined design can produces 2-3m/s speed three-dimensional wind, and makes you feel like enjoying the natural breeze system.It promotes the dispersion of smoke, moisture, carbon dioxide and poor air with high specific gravity.So as to improve the quality of working area, create healthy, dry and safe working environment, improve working efficiency.
2)convenience
It is convenience to be operated, control system adopts the latest poleless frequency converter control system.besides of convenience operation, the humanized operation interface also allows you enjoy the beauty of electronic and mechanic achieve the life.

Dehumidification

Because it can produce large air volume, effectively promote air circulation, so that the moisture is well dispersed, greatly reducing the probability of problems such as bedbugs, fungi and so on.
4)beautiful and durable
After complex surface treatment,the product can avoid the pain of period cleaning,the cost-performance ratio is the highest,the life of each fan can reach more than10 years.

energy saving

The rated power of the motor on the fan is 1.5KW,each fan can cover 1000 square meter working area,8 hours per day, is just 10 degree power energy consumption,compared to typical small fans and high power consumption air condition, large industrial ceiling fan can be called model of energy saving, can greatly reduce your operation cost.
working principle :
Large ceiling fan is a series of products special developed for energy saving,working environment improvement. As we all know,refrigeration is not the only way to achieve the effect of cooling and comfort. The area of a fan could blow is determined by the diameter dimension of it, but has nothing to do with its speed.therefore, the industrial fan with large diameter and low speed combines all these characteristics .
After years deeply research and exploration,by integrating oversea advanced aeronautic technology,we Dai sen developed a kind of propeller blades with outstanding performance,it conforms continuous and silent breeze by slowly rotation.The large volume of airflow generated by its unique and high efficient blades push down,thus a nearly perfect propeller exhaust is constructed.
It pushes large volume of airflow to the ground,and constructed certain high level airflow moving horizontally,thus generates a overall air circulation.The advantage is overall ground coverage and three-dimensional circulation of air.
The speed of wind generated by"Large industrial ceiling fan"is about 1-3m/s,completely calculated according to the best feeling of cooling when the airflow pass through human skin.too strong airflow makes people feel irritable,a sense of being blown directly,too high speed of airflow also makes people dizzy,only the through the evaporation of skin combines of breeze speed,can beautifies people's feeling of cooling.

Comparison of three refrigeration methods in 1000 square meter plant

Refrigeration mode	Quantity	Power/unit	Tall power	General comparison
Central air conditioner	1	80KW	80KW	The walls and doors and windows of the plant are required to be insulated. The cost of one-time investment of the equipment is high, and the maintenance cost of replacing the filter element and adding refrigerant is high
Traditional industrial fan	40	0.3KW	12KW	The installation of traditional wall fans is limited by walls and columns. The power lines of floor fans are scattered, which has potential safety hazards. It is not safe for the hair of staff members to be mixed into the fan blades, which occupies a small space and covers a short service life
7.3M large industrial ceiling fan	1	1.5KW	1.5KW	Large coverage area, long service life, low maintenance cost, installation does not occupy the workshop space, safety and environmental protection

The energy consumption of large industrial ceiling fan is about 1 / 50 of that of central air conditioner and 1 / 10 of that of traditional industrial wall fan

***Suitable places of installation: Any high enough structure of factory,sport center,logistic place,car repair workshops,supermarket, airport,package workshop,animal breading industry,any kinds of hall,as well as fitness center etc.
***Height of installation: "Fengshen" series products for 6 meters to 20 meters height.
"Fengxing" series products for 3 meters to 6 meters height.
***Solutions for the three main kinds of installation structures as above shown pictures.
