Zone 2 Diesel Generator Design
RADIATOR SUITABLE FOR SALINE ENVIRONMENT
The solder-dipped radiator core is sized to meet engine and exhaust gas cooling requirement
FLAME ARESSTOR AND SHUT DOWN VALVE
Inlet shutdown valve provides automatic shutdown on overspeed
INTEGRATED FLAME ARESSTOR AND EXHAUST GAS HEAT EXCHANGER
Diesel Engine inside DNV 2.71 Container Cools the engine Exhaust Gas below 200 ° C and ensures no hot particles into the atmosphere
EXHAUST SPARK ARRESTOR / SILENCER
Provides exhaust gas sound attenuation below 85dB and trap the spark
RADIATOR FAN WITH GUARD / ANTI -STATIC BELT
Axial pusher type of fan provide adequate cooling for the radiator fins. Fan guard according to 98/37/EEC. Static discharge can pose a hazard on belt drives that operate in potentially explosive environments. Radiator belts meets RMA static conductivity requirements
FLAME PROOF PANEL Exd, IP66, Alloy Aluminium panel to house engine controllers. Controller provide automatic engine shutdown on Lube Oil Pressure Low, Coolant Temperature High, Exhaust Temperature High and Overspeed,.
INCREASED SAFETYBATTERY ENCLOSURE
Maintenance free lead acid battery is housed in Exe battery enclosure. Batteries provide power for the electric starter and panel. Using flame proof battery isolator batteries can be isolated during maintenance. Engine driven flame proof DC alternator will charge the batteries.
ENGINE PACKAGE BASE FRAME
Base frame with drip pans provide spillage free of oil. Diesel Fuel tank embedded with the base frame sized for 12hours of 100% load operation.
ENGINE PACKAGE INSTRUMENT
Flame proof type of lube oil pressure switch, coolant temperature switch, exhaust temperature switch and speed sensor. Engine gauge board for (lube oil pressure gauge, coolant temperature gauge, exhaust temperature gauge, tachometer & run hour
Capacity: 10HP-600HP
Zone 2 Diesell Engine Design: A typical Atex Zone 2 engine includes features designed to prevent an ignition source causing an explosion in the event of a hydrocarbon release.
Air Inlet Flame Arrester with Shut-off Valve
Provides shutdown on overspeed
Water-cooled Turbocharger and Exhaust Manifold
Ensures surface temperature is below 200oC (T3)
Exhaust Gas Heat Exchanger
Cools the engine exhaust below 200oC (T3)
Spark Arrestor
Ensures that no sparks or hot particles escape into the atmosphere
Radiator
The solder-dipped radiator core provides additional cooling capacity
Hiersun explosion-protection technology was developed to guard against these and many other dangers.
Explosion protection also includes:
• Battery and electrics
• Charge air pipe
• Automated shut-off system
• ECM
Certification and Testing
All engines are certified, with some having tri-certification to
ATEX 94/9/EC, IECEx, and NEC 505/NEC 500. With in-house test facility procedures and approval to national standards, Hiersun ensures quality at every step in the process.
