Smoke Density Detector
The G1000 used to detect the smoke emission from ships. G1000 is effective equipment that checks the discharged smoke to prevent fines and investigation caused by polluting of environments.


Ambient Oil Mist Detector
The G2000 used to detect the oil mist in open spaces to protect ship and crew from fire. It detects oil that was converted to mist during Hydraulic Installation or oil system under pressure.

Boiler Protection

  G5000 / G5200

Exhaust Gas Economizer Monitor
The G5000 EGEM is used to monitor the temperature and the pressure of the boiler. The common accidents in boilers are caused by Soot-fire in exhaust gas economizers due to low grade fuels and reduced engine speed. The installation of the G5000 provides the data on pressure drop and temperature in comparison to current load. It also provides the monitoring of water circulation to boiler to prevent over soot burning developed into high temperature fires and boiler meltdown.
  • Features:
    • Maintain Economizer / Boiler Efficiency
    • Prevent Soot-Fires
    • Cost-Effective Protection Against Costly Damages
    • Direct Alarm for Low Water Circulation (G5000)

Oil-Fired Boiler Monitor
The G5000 is the modular system designed to monitor the boiler’s thermal condition and furnace back-pressure. The G5000 provides the indication of the potential problems e.g poor combustion and soot deposits on the gas side and the scale build-up or oil contamination on the water side.
  • Features:
    • Configurable Measuring Range and Output
    • Configurable Alarms
    • Easy Integration to Boiler Control System
