Weather Proof Zone Control Station , Anti Dust Control Box For Dangerous Area

weather proof zone control station and anti-dust control box for dangerous area

Description:

  The explosion proof custom control stations can be built to customer specifications with door-mounted pushbuttons, pilot lights, selector switches, or potentiometers. Any combination of devices can be assembled in one of 20 sizes of aluminum enclosures. Custom Push-Button Stations are for applications requiring only operator interface and/or pilot light indication. Stations are available in one-hole to nine-hole arrangements. Operators can be purchased separately. Custom Control Stations Control stations are used to house control components and have the ability to add operators on the cover. The enclosures are available in 20 shapes and sizes that fit any application. Window Enclosures are available with square or rectangular windows. This provides convenient viewing of gauges, meters, or control device displays. Circuit Breakers provide overload and short-circuit protection on feeder or branch circuits, as well as lighting, heating, and motor circuits. The enclosure includes an external breaker operator handle that can be padlocked in on or off position. The circuit breaker can be used as a general service disconnect.

Techinical parameters:

The dust site is divided into three areas: 20, 21 and 22:

Zone 20: Combustible dust continuously or frequently occurs during normal operation in an amount sufficient to form a mixture of flammable dust and air and/or a location and container interior that may form an uncontrollable and extremely thick dust layer.

Zone 21: During normal operation, there may be a place where the amount of dust is sufficient to form a mixture of flammable dust and air but not zoned 20. This area includes locations directly adjacent to the charge or discharge of dust, where dust layers and flammable concentrations of flammable dust and air may be produced under normal operating conditions.

Zone 22: Under abnormal conditions, flammable dust clouds occur occasionally and are only present for a short period of time, or flammable dust occasionally accumulates or may present a dust layer and produce a flammable dust air mixture but not zoned into Zone 21. If it is not guaranteed to exclude flammable dust accumulation or dust layer, it should be divided into 21 zones.

Applications:

1. Explosive gas mixture hazardous locations: Zone 1 and Zone 2.

2. Explosive gas mixtures: IIA, IIB, IIC.

3, flammable dust environment:20,21,22 area

4, explosion-proof signs: ExdeIIBT6, ExdeIICT6
