Heat Detector JTW-ZD-3100 – Reliable Marine Fire Detection

The JTW-ZD-3100 heat detector is a robust fire detection device engineered for demanding marine environments. Designed to sense abnormal temperature rises in ship compartments, engine rooms, and accommodation areas, this detector provides rapid and reliable alerts, ensuring compliance with international maritime safety regulations. Its sturdy construction and corrosion-resistant housing make it ideal for offshore and onboard applications where reliability is non-negotiable.

The detector operates on a fixed temperature and rate-of-rise principle, quickly responding to both rapid temperature increases and preset temperature thresholds. This dual-function capability minimizes false alarms while ensuring maximum sensitivity to genuine fire conditions. The JTW-ZD-3100 is compatible with most conventional fire alarm control panels and is easy to install and maintain, making it a preferred choice for ship chandlers and marine safety officers worldwide.
