Specifications
| Zone Rating | Zone 1 / Zone 2 |
|---|---|
| Components | Enclosures, arrestors, sensors, starter & charging systems |
Flame Proof Exd Enclosure
Explosion-protected enclosure (SEBX family) for housing electrical components in Zone 1/Zone 2 areas.
Start Battery
Ex eb-rated starting battery (SEB/T/S/A family) for hazardous-area diesel/gas engine starting systems.
Ex d Battery Connector
Ex d-rated battery connector (SESP family) for safe hazardous-area battery circuit connection/disconnection.
Start Motor
Ex d-rated explosion-protected starting motor (SESTM family) for hazardous-area diesel/gas engines.
Charging Alternator
Explosion-protected charging alternator (SEALT family) for hazardous-area engine charging systems.
| Output | Typ. 24V/55A or 12V/70A (confirm exact rating from nameplate) |
|---|---|
| Protection Type | Ex d |
| Temperature Class | T3–T4 typical |
Note: identified from a second-pass review of the supplied photos, not explicitly labelled by SunEx — please confirm this is the correct component before treating the exact output rating as final.
Flame Arrestor
Exhaust flame arrestor is designed and tested to extinguish explosions created in the exhaust system. The flame arrestor is sized to operate within the backpressure limit of the engine. All SunEx inline exhaust flame arresters are constructed from stainless steel.
The engine must not be used in a hazardous area without exhaust flame arrestor fitted. The Person in Authority must be consulted before starting the engine after installation.
Inlet/exhaust flame arrestor (SEFA family, 40–350mm) for gas and mining applications, arresting flame propagation through piping.
| Size Range | DN40–DN350 (SEFA family) |
|---|---|
| Application | Inlet (IIB) / exhaust duty |
| Standard | 2014/34/EU ATEX; EN-1834-1:2000; EN-1834-2:2000 |
Spark Arrestor
Designed for fitting into and suppressing sparks emitted by a diesel engine exhaust system (engine configurations with a nominal inlet velocity of 55-75m/s). Made from stainless steel, it is designed as a cylindrical ‘can’ with inlet and outlet pipe studs containing serrated and louvered inner tube welded to it.
| Application | Diesel/Gas engine exhaust systems |
|---|---|
| Range | 90-320mm in diameter |
| Efficiency | Typ. >99% spark capture (confirm actual rating) |
| Standards | EN 1834-1:2000 - EN 1834-3:2000 - EN 1834-2:2000 |
| Certificate No. | AR20ATEX002U |
Ex mb Sensors
Encapsulated Ex mb-rated sensors (SEN family) for engine/system monitoring in hazardous-area applications.
| Type | Pressure / temperature / speed sensing (confirm which) |
|---|---|
| Protection Type | Ex mb (encapsulation) |
| Output Signal | TBC — typ. 4–20mA or digital |
The I.S. barrier above is a system-level reference (a CAD rendering, not a photo) showing how these sensors are typically wired into an intrinsically-safe circuit — not a SunEx-branded product photo.
LED Lights
Encapsulated Ex m-rated LED lighting (SELT/SELR family) for hazardous-area illumination and status indication.
