Fixed Gas Detection System · Gas Detection
Crowcon Crowcon Xgard LEL is a fixed marine gas-detection system. It is normally installed at permanently selected sampling or detector locations with signals returned to a central alarm or monitoring panel. Its primary purpose is to provide continuous warning of hazardous gas concentration or oxygen conditions in designated ship spaces. Compared with portable detectors, fixed systems provide continuous unattended monitoring but depend on correct detector siting, calibration, power and alarm integration. The supplied record already contains the available concise model or rating information, so those existing figures are not duplicated here and no additional meaning is inferred from the model code. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.

What our service work and the manufacturer documentation say about keeping this model running.
Inspect detector heads, sample paths, filters, cabling, power, alarm panel and environmental condition. Perform bump tests and calibration using the approved gas and procedure. Review alarm history and verify remote alarms and shutdown interfaces where fitted. Exact calibration concentrations and alarm settings require manufacturer and vessel documentation.
Carry detector cells or sensor cartridges, filters, pump or flow parts for aspirated systems, calibration adapters, fuses, transmitter modules and approved calibration gas under the vessel's gas-detection program.
