Product Features

1. The shell is made of high-quality carbon steel or stainless steel welded and formed, with high-pressure electrostatic spraying treatment on the surface, which is corrosion-resistant, anti-static, firm and reliable;

2. Modular structural design, positive pressure chamber and control chamber can be combined in various ways such as up and down, left and right, front and rear, or can be installed separately;

3. Equipped with a gas pressure regulating and filtering device, users only need to introduce on-site industrial gas sources and do not need to install other gas source components;

4. Equipped with spark and particle baffles, the positive pressure chamber can discharge gas locally, ensuring safety and reliability;

5. The control system adopts a PLC programmable logic controller, which is stable, reliable, and has fast response speed;

6. Humanized human-machine interface, LCD text display, integrating multiple functions, reducing control system panel buttons and indicator lights;

7. Equipped with communication interface, it can achieve remote centralized monitoring and control;

8. Real time monitoring of important parameters such as positive pressure chamber pressure and flow rate;

9. The sensor signal type and signal value range can be set;

10. The delay time before formal air change can be set to ensure that combustible gases are completely discharged before the positive pressure chamber is powered on;

11. According to the on-site gas source pressure situation, the working pressure range, alarm pressure range, and positive pressure chamber power cut-off pressure range can be set by oneself;

12. Set the size of the positive pressure chamber according to the actual situation to improve the universality of the control program;

13. The program automatically calculates the duration of ventilation based on relevant parameters;

14. Modular program design, which can achieve different control functions by simply loading different programs;

15. Equipped with a system fault analysis program and flashing text on the human-machine interface to prompt users for easy maintenance;

16. Various detection instruments, analysis instruments, display instruments, low-voltage electrical appliances, frequency converters, soft starters, and various electrical control systems can be installed in the positive pressure chamber, making it flexible and versatile.
