Jiangsu Jinhang Machinery Manufacturing Co., Ltd.: Founded on April 22, 2013, the company is located at No. 9 Lifa Avenue, Chengdong Town, Hai'an County, Jiangsu Province; mainly: printing machinery, CNC machine tool production, automobile parts and accessories manufacturing, Steel roller processing, self-operation and agency for import and export of various commodities.

The workshop area is 150 meters long, 80 meters wide and 14 meters high. Due to the mildly hot weather in summer, the ambient temperature of the workshop is high, coupled with the heat generated by the equipment and welding smoke, the air quality in the workshop cannot be discharged and the outdoor air does not circulate. It is very hot and stewed. It is uncomfortable, and incidents such as heatstroke may occur among staff members in such an environment.

Mr. Zhu found the Xiaviyi brand through Baidu online. Our company immediately sent professional engineering and technical personnel to the site to conduct on-site survey, planning and data collection of its production workshop environment. Our technicians communicated with Mr. Zhu on site and learned that the current main problem in his workshop is the large amount of heat sources generated during equipment production, which prevents air convection in the workshop, and the welding smoke cannot be discharged in time, making it stuffy and hot. In such an environment, workers People feel tired, and heatstroke often occurs. Mr. Zhu put forward the improvement goal of ensuring that the air flow in his workshop can be discharged to the outside, and the outdoor air flows into the indoor air convection effect.

We took Mr. Zhu to our company's existing successful project cases to see the effect of negative pressure fans combined with industrial large ceiling fans. The technical staff discussed the specific ventilation plan with Mr. Zhu of your company many times, and finally selected the negative pressure fan to exhaust hot air and industrial ceiling fans. The large ceiling fan cooperates with the rapid convection in the workshop, and the negative pressure fan discharges a large amount of hot air and welding smoke generated by the workshop production equipment in a timely and effective manner. Through the disturbance of the large air volume in the workshop by the industrial large ceiling fan, the workshop forms indoor air flow, disturbing the air circulation, and employees The body temperature is reduced, and the entire workshop will not be stuffy.

The contract was signed on June 27, 2023, and the project was completed on July 20. The installation, commissioning, and delivery acceptance were completed on July 20. Mr. Zhu said that no employees in the workshop suffered from heat stroke after the ventilation system was installed. Mr. Zhu and the employees were very satisfied with the good ventilation effect.
