The explosion-proof positive pressure cabinet is composed of a cabinet body and a positive pressure purge control system. The positive pressure purge control system provides the air source, and the cabinet is purged. When the low voltage alarm, a signal alarm will be sent out, and the power supply will be cut off.
The automatic control system can realize the functions of air exchange, air supply, ultra-high voltage automatic pressure relief, low-voltage alarm and low-voltage interlock power-off.
The air intake type is divided into continuous purge type and leakage compensation type. Continuous purging type continuous air supply, which can dissipate heat; The leakage compensation type has good sealing performance and low air consumption.
It has reliable sealing performance and multiple sealing protection, which can maintain pressure for a long time and save operating costs.
A variety of instruments and control systems can be installed inside, such as detection instruments, analysis instruments, display instruments, low-voltage electrical appliances, frequency converters, soft starters or computer control systems, which can be used as signal processing systems and control systems.
The positive pressure purge control system has complete protection devices, including high and low voltage automatic alarm, lower pressure limit, automatic power off when opening the door and emergency manual power off and other safety interlock protection.
The structure has a box type, a piano table type and a cabinet type. The cabinet type can be divided into upper and lower structure and left and right structure. The box type is welded with steel plates, and the piano table and cabinet type are treated with special seals.
Explosion-proof positive pressure cabinet can adapt to the needs of a variety of industrial scenarios. With reliable sealing performance and multiple protection devices, it can ensure the safe operation of the cabinet and the safety of operators. It can be customized according to the requirements of individual industrial scenarios.
