Description Features Advantage installation

Low cost, low energy consumption, high efficiency

It only needs 1.5kw of power and covers a work area of more than 1200 square meters. If the use cycle is 10 years, the overall cost (including equipment purchase and daily electricity cost) is only 1/4 of the wall-mounted shaking head fan (covering the same area) .

Natural three-dimensional wind

The comfort level brought by industrial energy-saving fans is unmatched by other fans. Under the industrial energy-saving fans, you will feel three-dimensional wind from all directions to cover the entire body, allowing the sweat to evaporate, forming a natural-like appearance. The breeze system. However, the traditional high-speed fan blowing directly on the human body at high speed not only makes the human body feel uncomfortable, but also forces the body temperature of parts of the body to drop sharply, which will bring about various health problems, such as common fan diseases. HVLS series industrial fans combine the actual needs of different occasions, and the wind speed range of 1m/s~5m/s can be adjusted arbitrarily.

Large coverage

The HVLS series of industrial energy-saving fans can cover an area of up to 1200 square meters per unit. The reason why they can cover such a large area depends on the unique blade profile design, which can reduce the resistance to a small amount and convert the electrical energy efficiency into the kinetic energy of the air. . In addition, the airflow structure of the fan is also different from ordinary small fans. Small fans can only cover the range of the fan diameter. Industrial energy-saving fans first push the airflow vertically to the ground, and then form an airflow layer of 1~3m on the ground. The formation is not limited to a large coverage area under the industrial energy-saving fan. In an open space, a fan can even cover a large area of more than 1500 square meters.

Promote massive indoor air flow

The powerful air agitation ability keeps the indoor air flowing in a large space, improving the stuffiness and comfort. In the humid season, keep the surface of the object dry. In the northern winter, by promoting the exchange and flow of indoor roof and ground air, the hot air floating in the upper space is brought back to the ground, saving heating costs.

Staff cooling

The natural breeze generated by the large energy-saving fan blows on the human body, which promotes the evaporation of sweat to take away the heat, which cools the human body and brings a cooling feeling. Usually, this cooling sensation can reach 5-8°C. The three-dimensional natural wind blown by the super-large energy-saving fan is more comfortable because: on the one hand, the three-dimensional blow on the human body maximizes the evaporation area of the human body, and on the other hand, humans have accumulated a kind of natural wind in the natural world. Experience, once the natural breeze with varying wind speed blows, the human body naturally feels extremely comfortable and cool.

Workshop ventilation

In the past ventilation schemes, people often decide which product and quantity to use based on the number of air changes in the space. In a small space, this effect is very obvious. You can even see the steam in the bathroom quickly vented outside the house with the operation of the negative pressure fan. However, in a large and wide enclosed space, the effect of this kind of ventilation is not obvious: the smoke, humidity, and carbon dioxide with a relatively large specific gravity are still concentrated at the bottom of the building, and the roof negative pressure fan affects the air in every corner. Doesn't work.

Dehumidification

Large energy-saving fans promote air mixing in the entire space, which can disperse and absorb unpleasant fumes, moisture, etc., thereby improving indoor air quality and obtaining a healthy, dry and safe working environment. Other benefits are the elimination of birds and bed bugs, as well as the noise and rot caused by humidity that other ventilation solutions are prone to.

Noise reduction technology

The tail wing of the fan blade is not only beautiful. According to the knowledge of fluid mechanics, the air will form a vortex at the fan blade tail when the fan blade rotates and lose part of the energy. After the tail wing is added, the fan can run stably and play a certain role in noise reduction. The Teflon film is inserted between the fan blade and the petiole to reduce the heat caused by friction and at the same time reduce the noise caused by vibration and friction.

Energy-saving technology

Frequency conversion speed regulation and servo control technology enable the fan to run continuously according to the set parameters, smoothly regulate the speed, avoid the inrush current caused by frequent start and stop, and greatly save energy consumption. Intelligent monitoring and management not only prolongs the service life of the fan, improves comfort, but also saves energy.

Quality Control Technology

Before leaving the factory, each motor and frequency conversion cabinet shall be set to functional parameters, with load aging and dynamic balance testing; each fan has a built-in universal leveling indicator to ensure that the installer directly monitors the installation effect and is also used as one of the indicators to evaluate the installation quality .

Safety measurement

For different structural forms and materials: each component of the product has undergone rigorous calculations and software simulations: the material performance and product safety are measured on the spot: each product has a unique ID code from birth: throughout the entire life of the product Cycle, convenient for internal management and quality tracking. Contains product processing, assembly, installation and debugging, maintenance and other information.

Installation conditions:

● Building structure: H-beam, I-beam, brick-concrete square beam, spherical column structure, etc.;

● The installation point of the Dofine series should not be less than 4.5m above the ground;

● The installation point of Refine series is not less than 3.5m from the ground;

● The safety distance between the fan blade and the obstacle is not less than 0.2m;

● Input power: 380V/220V are optional.
