Atex Generator and Atex Diesel engines operating in Zone 2 hazardous areas present a risk of explosion. The flame protected engines used by Hiersun Power operate below 200°C. This lower operating temperature, combined with additional shut down features,
means the equipment can be used in areas where there is a strong potential explosion hazard.
And with the addition of the available Zone 2 explosion protection equipment, the engine system is certified to the Zone 2 hazardous location requirements detailed in the ATEX directive 94/9/EC.
Engine – Cummins or Perkins engine with water-cooled turbo housing and exhaust manifold keep engine surface temperature below 200ºC (392ºF).
Cooling System – Two-pump, two-loop cooling system for optimal engine performance and ease of installation.
Fuel System – fuel system optimizes combustion for increased engine performance and fuel-efficient operation.
Exhaust System – Water-cooled exhaust gas heat exchanger
Air Inlet – Automatic air inlet shutdown available to shut down the engine in the presence of a flammable gas mixture.
Emission Certification – EPA/CARB Tier2 or Tier 3, Marpol Tier 3.
Control System – Electronic components certified to ATEX Directive 94/9/EC Group II, Category 3G requirements.
Corrosion Protection – Uses the Corrosion Protection package including e-coated brackets, pre- and postassembly
block and head priming and stainless steel plugs.
Zones are used to define the probability of presence of flammable materials
Groups classifies exact flammable natures of materials Protection Types are used to denote the safety levels of the devices. Equipment approved receives temperature codes indicating maximum surface temperature of the equipment.
The zone defines the probability of hazardous material being present in an ignitable concentration in the surrounding atmosphere.
Zone 0 | Area in which an explosive gas-air mixture is continuously present or present for long periods. |
Zone 1 | Combustible or conductive dusts are present. Area in which an explosive gas-air mixture is likely to occur for short periods in normal operation. |
Zone 2 | Area in which an explosive gas-air mixture is not likely to occur, and if it occurs it will only exist for a very short time due to an abnormal condition. |
Different protection techniques are used to address the hazardous zones.
EX | Zone | |
Ex d | Flameproof (Explosion proof) Enclosure | 1, 2 |
Ex e | Increased Safety | 1, 2 |
Ex ia | Intrinsically Safe | 0, 1, 2 |
Ex ib | Intrinsically Safe | 1, 2 |
Ex o | Oil Immersion | 2 |
Ex p | Pressurized Apparatus (Purged Apparatus) | 1, 2 |
Ex q | Powder Filling (Sand Filling) | 2 |
Ex m | Encapsulation | 1, 2 |
Ex n or Ex N | Non incentive or/and normally no sparking circuits | 2 |
A mixture of air and hazardous gases may ignite by coming in contact with a hot surface. An ignition depends on surface area, temperature and the concentration of the gas.
Certified equipment are tested for maximum temperature ratings by approval agencies. Equipment for Group II receives a temperature code indicating the maximum surface temperature.
Temperature Code | oF | oC |
T1 | 842 | 450 |
T2 | 572 | 300 |
T3 | 392 | 200 |
T4 | 275 | 135 |
T5 | 212 | 100 |
T6 | 185 | 85 |
The coding is based on a 104 oF (40 oC) ambient temperature.
Electrical equipment are divided into two groups where Group I covers equipment used in mines and Group II covers all other applications. Group II is subdivided into three subgroups where the specific hazardous materials within each group can be found in CENELEC EN 50014.
Group I For application in below ground installations (mines) where methane (firedamp) and coal dust may be present.
Group IIA For application in above ground installation where hazards due to propane may exist.
Group IIB For application in above ground installations where hazards due to ethylene may exist.
Group IIC For application in above ground installations where hazards due to hydrogen or acetylene may exist.
Increased Safety
Electrical circuits incorporates special measures to reduce the probability of excessive temperatures and the occurrence of arcs and sparks in normal service.
The electrical energy available in circuits and equipment, is limited to a level to low to ignite the most easily ignitable mixtures in a hazardous area.
Intrinsically safe barriers, as Zener, are installed in the circuit to limit current and voltage in the hazardous areas to avoid sparks or hot spots under fault conditions.
