The Consilium Salwico ST400 is an electrochemical oxygen (O2) gas detector designed for continuous atmospheric monitoring aboard commercial and industrial marine vessels. Manufactured under the Consilium Marine AB and Buveco Gasdetection B.V. collaboration, this detector measures oxygen concentration across a 0–25% range, making it a critical component within onboard fire alarm and gas detection systems. Accurate O2 monitoring is essential for crew safety, particularly in enclosed or confined spaces where oxygen depletion or enrichment poses a serious risk to personnel and vessel operations.
Key Features
✓ Electrochemical O2 sensing element with a detection range of 0–25%, providing reliable continuous monitoring of oxygen levels in the surrounding atmosphere.
✓ Rated for an ambient temperature range of -40°C to +60°C, with electrical parameters of UI=28V, CI=30nF, LI=1mH, and PI=0.75W as specified in the product data — suitable for installation in demanding marine environments.
✓ Compatible with the Salwico ST400EX system platform (terminals 18/19/20), designed to integrate with Consilium Salwico gas detection control panels and fire alarm system infrastructure.
✓ BUTOX type ST401EC construction reflects an intrinsically safe design concept, appropriate for use in potentially hazardous locations onboard — exact certification details subject to confirmation against vessel documentation.
✓ Replacement and service of this detector should be carried out in accordance with Consilium Salwico system maintenance schedules to preserve system integrity and detection reliability.
Marine Applications
✓ Engine rooms and machinery spaces aboard cargo vessels, tankers, and offshore support vessels where oxygen monitoring is required for personnel safety.
✓ Pump rooms and enclosed cargo handling spaces on chemical and product tankers where atmosphere control is operationally critical.
✓ Confined spaces including void spaces, chain lockers, and ballast tanks subject to enclosed space entry procedures requiring gas monitoring.
✓ Integrated into Consilium Salwico fire alarm and gas detection systems on ferries, cruise ships, and naval auxiliary vessels.
✓ Offshore platforms and FPSOs where continuous atmospheric monitoring supports both safety management systems and regulatory compliance requirements.
