Marine Boiler Exhaust Gas Temperature High Alarm
The marine boiler exhaust gas temperature high alarm is a critical safety device designed for ship‑board boiler systems. It continuously monitors the temperature of exhaust gases and instantly signals an over‑temperature condition, allowing crew to take corrective action before equipment damage or fire risk occurs. Engine rooms, auxiliary boilers, and offshore platforms rely on this alarm to meet classification society requirements and to protect costly assets.
Key Benefits & Features
- Rapid response: Audible and visual alerts activate within 0.5 s of exceeding the preset set‑point.
- Robust construction: Marine‑grade stainless‑steel housing (SS316) resists corrosion in salt‑laden environments.
- Adjustable range: Temperature set‑point can be programmed from 120 °C to 350 °C in 1 °C increments.
- Fail‑safe design: Dual‑circuit wiring ensures alarm function even if one sensor line fails.
- Compact footprint: 150 mm × 80 mm × 50 mm size fits tight control panels without sacrificing performance.
- Integrated diagnostics: Self‑test mode reports sensor integrity via a 4‑digit LED display.

All parameters can be fine‑tuned to match the specific boiler design and classification society thresholds. Our engineering team provides firmware updates and calibration support throughout the product life cycle.
Application Scenarios
The alarm is deployed in a range of maritime environments where boiler exhaust temperature must be tightly controlled:
- Main propulsion boilers on container ships and tankers – preventing overheating during high‑speed runs.
- Auxiliary steam generators on cruise liners – safeguarding hotel‑water systems and HVAC plants.
- Offshore platform boiler rooms – meeting strict fire‑safety regulations under extreme weather.
- Naval vessels with dual‑fuel boilers – integrating with existing integrated bridge systems (IBS).
In each case, the marine boiler exhaust gas temperature high alarm fulfills classification society requirements (e.g., ABS, DNV‑GL) and supports the vessel’s safety management system (SMS).

Frequently Asked Questions
What is the minimum order quantity (MOQ) for the alarm unit?
We accept orders starting at 10 pieces. Larger volumes receive tiered pricing and priority production slots.
Can the set‑point be customized to match specific class society limits?
Yes. The firmware allows custom temperature thresholds from 120 °C up to 350 °C. Our engineering team will program the required values before shipment.
What is the typical lead time after order confirmation?
Standard lead time is 15‑30 days for stocked components; for special configurations it ranges from 30‑45 days depending on the extent of customization.
Does the marine boiler exhaust gas temperature high alarm include a warranty?
All units ship with a 24‑month warranty covering material and workmanship. Extended warranty options are available upon request.
