JTWB-BCD-5151EIS Explosion Proof Heat Detector
Product Description
JTWB-BCD-5151EIS Explosion Proof Heat Detector
Product Introduction
Engineered for the highest risk areas aboard vessels, the Marine Explosion-Proof Heat Detector is a critical safety device designed specifically for fire detection in hazardous locations where flammable gases, vapors, or combustible dusts may be present. This robust detector ensures reliable thermal monitoring in classified zones such as pump rooms, paint lockers, fuel handling spaces, chemical storage areas, and offshore platform compartments, where standard detectors would pose an ignition risk.
Constructed with a heavy-duty, flameproof (Ex d) or explosion-proof enclosure, the detector is built from marine-grade corrosion-resistant materials such as stainless steel or copper-free aluminum to withstand harsh maritime conditions including salt spray, constant vibration, humidity, and extreme temperatures. It is certified to meet the most stringent international standards for hazardous area equipment, including ATEX, IECEx, SOLAS, and major classification society (ABS, DNV, Lloyd’s) requirements.
Utilizing a reliable fixed-temperature or rate-of-rise thermal element, the detector activates precisely when a preset temperature threshold is reached or when an abnormally rapid temperature increase occurs. Its design ensures that any internal electrical spark or thermal event is fully contained within the certified enclosure, preventing ignition of the surrounding explosive atmosphere.
