Product Features
Carbon steel shell surface treated with high-pressure electrostatic spraying; Shell made of carbon steel or stainless steel, welded for robust reliability;
Modular structural design, allowing the positive pressure chamber and control chamber to be combined in various configurations (top-bottom, left-right, front-back) or installed separately; Equipped with spark and particle baffles, the positive pressure chamber exhaust can be discharged locally, ensuring safety and reliability; Built-in gas pressure regulation and filtration device, requiring only the connection of an on-site industrial gas source without additional gas treatment components;
Control system utilizes a PLC (Programmable Logic Controller) for stable, reliable operation and fast response;
Includes a communication interface for remote centralized monitoring and control; User-friendly human-machine interface with LCD text display, integrating multiple functions to reduce control system panel buttons and indicators;
◆ Real-time monitoring of critical parameters such as positive pressure chamber pressure and flow rate; Capable of setting sensor signal types and value ranges;
◆ Adjustable delay time before formal ventilation to ensure complete replacement of flammable gases in the positive pressure chamber before power-on;
◆ Customizable working pressure range, alarm pressure range, and power cut-off pressure range for the positive pressure chamber based on on-site gas source conditions; ◆ Configurable positive pressure chamber dimensions to enhance control program versatility; ◆ Automatic calculation of ventilation duration based on relevant parameters;
Modular program design, enabling different control functions by loading different programs;
◆ Includes a system fault analysis program with flashing text prompts on the human-machine interface for easy maintenance;
The positive pressure chamber can accommodate various detection instruments, analytical instruments, display meters, low-voltage electrical devices, frequency converters, soft starters, and diverse electrical control systems, offering flexibility and adaptability.
