As one of the large-scale energy-saving fan enterprises in South China, Hengzhengtong has offices in Wuhan, Chongqing, Suzhou, Foshan, Yulin and other places, which can provide direct line marketing and operation and maintenance services. The corporate customers we have cooperated with include well-known brands such as JD.com, Foxconn, Vipshop, Midea, Guangzhou Railway Group, and CNR.
Hengzhengtong products have also obtained CE and ROHS certification in Europe and FCC certification in the United States. The brand has good technical strength in anti-falling. When installing, Hengzhengtong will put a vibration isolation rubber sleeve on the edge of the hub, if there is an external force hitting the blade, it can play a cushioning role, and insert the pin in the motor shaft to connect the hub and the motor to avoid the hub falling. Because the hub and petiole are combined in a mortise and tenon joint, the risk of the fan blade falling under the impact force can be reduced, and this result has been tested in real crash tests to prove that its technology is qualified and safe. In terms of fan blade effectiveness, Hengzhengtong realizes the blade upturn of 3-5 degrees, and the shape of the fan blade is variable cross-sectional width, which can expand the coverage area of the fan and improve the air supply effect. The control system is imported from Danfoss, which is controlled by touch screen, and can control up to 32 fans.
The development of Hengzhengtong's product line is becoming more and more perfect. From the beginning, it mainly focused on industrial fans, launched Hengtong, Hengkun, Hengxing, and Hengjie series, and later launched the Hengyun series for commercial use, and now it has also set foot in the field of residential fans and launched the Arrow series. However, although there are many types, the difference in product technical configuration is relatively small.
In terms of industrial fans, the size is complete, except for the Henghang series motor, which has a low power of 0.37kw, and the others are generally 1.5kw. Hengtong series adopts the 4-blade fan of the traditional geared motor, and can be equipped with German NORD or Lenze brands, with a maximum air volume of 13050m³/m, which is currently the first brand.
There is only Hengyun series for commercial use, and the difference between Hengyun and industrial fans is that Hengyun uses American permanent magnet synchronous motors, and the fans can be rotated forward and backward and LED lights are installed. In the case of the same type of motor, the same size is 7.3m, the air volume of Hengyun is only 12400m³/m, while the Fengyue 3 of Kailer is 14800m³/m, and the Fengyi 3 is 13100m³/m.
The installation height of Hengzhengtong industrial ceiling fan is more than 4 meters. The roof structures suitable for installation include I-beam beams, round steel beams, concrete beams, and round pipe beam structures.
