INERT GAS SYSTEM
Operation & Maintenance Graphical LCD operator terminal,
all major process parameters displayed
on the screen.
Burner combustion chamber in high
performance austenitic stainless steel
(ASTM N08904).
Easy access to burner and combustion
chamber by hinged burner front door
(no tools required).
Easy inspection and easy replacement
of scrubber components by entering
man hole and removable top plate.
Easy installation, panels are
connected via two pair serial data
wires + power supply (2 wires).
Options Multiple LCD operator terminals.
System signals and operation
available for ships IAS via MODBUS
or ETHERNET communication.
Brief Description Inert gas generation produce clean and
soot free inert gas by combustion of
air and gas fuel in Maritime Protection
burner/combustion chamber.
Automatic O2 regulation by
venturi and fuel pump motor
speed controller.
Efficientcoolingin
scrubber tower.
High pressure centrifugal
blower supplies air to burner
chamber and provides inert
gas to cargo tanks.
System capacity is auto-
matically controlled by
deck pressure set-point in
software.
Maritime Protection
Pressure Vacume
Breaker ensure safe
loading and
off loading.
Advantages Full automatic turn down (fuel saver)
Fully Automatic operated, no manual
operation (O2 content,IG-flow,alarmsetc.)
Easy maintenance
Oil spill prevention
Experience from continuous testing and delivered
projects are incorporated in our latest design
All generator units have a horizontal, recessed combus-
tion chamber. This construction retains fuel oil that, in
aeventofmisfire,wouldotherwisebedishargedover-
board. The PLC control logic has a specially designed
burnerignitionsequencethatwillensureaflawlessigni-
tion of the unit every time, hence further eliminating the
possibilityofaflamefailure.
LCD operator terminalFrom the terminal you can:
Start & stop the IG generator system.
Monitor valve positions and motor running status.
Change O2 set-point.
Monitor process and status indication.
Monitor alarm and change alarm set points.
Change controller set points and parameters.

PRODUCT TYPES:
INERT GAS GENERATOR: hFO/MGO/MDO/GAS fueled generator for inerting tankers.
FLEX SYSTEMS: Inert gas generator system in combination with exhaust gas from main engine or auxilary engines for fuel saving.
FLUE-GEN systems: Normal generator + flexinert venturi. Can be operated in two modes: 1. Generator mode 2. Fluegas mode with suction of flue gas from boilers through flex venturi and scrubbing in generator.
DUAL FUEL SYSTEMS: IGG, dual fuel-capable to use natural gas or mgo/mdo/hfo as fuel for inerting fpso’s/fsu’s.
INERT GAS GENERATOR DECK hOUSE MODULE: Application are tankers, fpso’s and oil barges. All systems and capacities available.
All our inert gas systems are skid mounted ready for hook-up.
