Pressurized Explosion-Proof Distribution Cabinet

Introduction
◆ Suitable for gas environments in Zone 1 and Zone 2;
◆ Applicable to gas environments of Class IIA, IIB, and IIC;
◆ Suitable for temperature groups T1 to T4;
◆ Ideal for hazardous environments such as petroleum extraction, refining, storage, chemical, and pharmaceutical facilities;
◆ Designed for explosion-proof treatment of products with large volumes, high internal component operating temperature rises, or complex electrical circuits;
◆ Available in two treatment types: dilution airflow and leakage compensation.

Product Features
◆ Housing made of carbon steel or stainless steel with welded construction, ensuring sturdiness and reliability;
◆ Carbon steel housing surface treated with high-pressure electrostatic spraying;
◆ 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 an integrated gas pressure regulation and filtration unit, requiring only the connection of an on-site industrial gas source without additional gas treatment components;
◆ Features spark and particle baffles, enabling safe and reliable local exhaust of the positive pressure chamber;
◆ Control system utilizes a PLC (Programmable Logic Controller) for stability, reliability, and fast response;
◆ User-friendly human-machine interface with LCD text display, integrating multiple functions to reduce control panel buttons and indicators;
◆ Includes a communication interface for remote centralized monitoring and control;
◆ Real-time monitoring of critical parameters such as positive pressure chamber pressure and flow rate;
◆ Allows configuration of sensor signal types and signal value ranges;
◆ Adjustable delay time before formal air exchange 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 based on on-site gas source conditions;
◆ Positive pressure chamber dimensions can be set according to actual requirements, enhancing the versatility of the control program;
◆ Program automatically calculates the duration of air exchange 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 instruments, low-voltage electrical devices, frequency converters, soft starters, and diverse electrical control systems, offering flexibility.
