“SAIEX” A Flameproof Start–Stop Push Button Control Station is an industrial control device designed to safely start and stop electrical equipment in hazardous (explosive) environments where flammable gases, vapors, or dust may be present.

 A flameproof start–stop push button control station is a locally mounted electrical control unit that houses Start (NO) and Stop (NC) push buttons inside a flameproof enclosure.

Its purpose is to: Control motors or machinery. Prevent ignition of surrounding explosive atmospheres. Contain internal sparks or explosions without transmitting them outside

Various Names: Flameproof Push Button Station, Explosion Proof Push Button Station, Ex d Push Button Control Station, Flameproof Start Stop Station, Hazardous Area Push Button Station, Flameproof Motor Control Station, ATEX Certified Push Button Station, Gas Group Push Button Control Unit

How It Works

1. Start Button (Green – Normally Open)
   • When pressed, it completes the control circuit
   • Energizes a contactor or relay
   • Starts the motor or equipment
2. Stop Button (Red – Normally Closed)
   • When pressed, it opens the control circuit
   • De-energizes the contactor
   • Stops the equipment
3. Any spark or arc generated inside the enclosure:
   • Is contained within the flameproof housing
   • Cannot ignite the external hazardous atmosphere

Where It Is Used (Applications)
Industries: Oil & Gas plants. Refineries. Chemical & petrochemical plants. Fertilizer plants. Paint and solvent industries. LNG terminals. Offshore platforms. Coal mines (with suitable certification)

Typical Equipment Controlled: Motors, Pumps, Compressors, Conveyors, Mixers, Fans and blowers 

Advantages: Safe operation in explosive atmospheres. Robust and long service life. Simple and reliable motor control. Compliance with international safety standards. Low maintenance

PVC HOOD
A PVC hood is a protective flexible cover made from polyvinyl chloride (PVC), used to shield external accessories of flameproof equipment from environmental damage.
In flameproof installations, a PVC hood does not provide explosion protection itself; instead, it offers mechanical and environmental protection to certified components such as cable glands and adapters.

Various Names of PVC Hood: PVC Hood, Protective Hood, Cable Gland Hood, Weatherproof Hood, Dust Cover, Rain Hood, Rubber Hood.

Common PVC Hood Sizes
PVC hoods are supplied to match standard cable gland sizes, such as:
·         M20
·         M25
·         M32
·         M40
·         ½″, ¾″, 1″
They are selected based on the outer diameter of the gland, not the enclosure entry size.
 
How a PVC Hood is Used
·         Slipped or pulled over the outer body of a cable gland or accessory
·         Covers:
o    Cable gland
o    Adapter
o    Reducer
·         Provides a tight fit around the cable
·         Does not interfere with the flamepath or threads
·         Easily removable for inspection or maintenance
PVC hoods are typically:
·         Installed after gland tightening
·         Used without adhesives or fasteners
 
Where a PVC Hood is Used
PVC hoods are used in flameproof equipment installations where external protection is required, such as:
·         Outdoor hazardous areas
·         Dusty or corrosive environments
·         Rain-exposed installations
·         Marine and coastal locations
·         Chemical plants, refineries, and offshore platforms
·         Flameproof junction boxes, panels, and lighting fixtures
Purpose of Using PVC Hood in Flameproof Equipment
·         Protects gland threads from corrosion
·         Prevents dust and dirt accumulation
·         Reduces direct water exposure
·         Improves service life of metal accessories
·         Provides neat and finished appearance
