Technological Principle of Explosion-Proof Pressure Cabinet

The product utilizes a GGD distribution cabinet frame, featuring a main and auxiliary panel structure. The entire cabinet includes a ventilation system, pressure sensing system, automatic control system, air exchange system, measurement system, and electrical system.

Products can be internally equipped with detection instruments, analytical instruments, display instruments, low-voltage electrical appliances, variable frequency drives, soft starters, or computer control systems, serving as central signal processing and central control systems.

The protective device is complete, the control cabinet is equipped with an air exchange interlock device, power supply is automatically initiated only after the specified air exchange time is reached, featuring low-voltage automatic alarm and automatic gas replenishment, as well as high-voltage automatic shutdown function.

Explosion-proof positive pressure cabinet product features:

Reliable sealing performance; housing with multi-seal protection, long pressure retention, cost-effective operation

This cabinet is installed using a cable trench mounting style; the user must provide a clean or inert gas source.

Multiple units can be installed side by side and operated in parallel.

During manufacturing, the customer must provide a complete electrical system diagram and a list of materials installed in the control system.
