RadioHeat 125 Series – Wireless Heat Detector

RadioHeat 125 GRP Series is a robust wireless heat detector solution designed for industrial, hazardous area, and safety-related monitoring applications. The solution combines reliable fixed-temperature heat detection with Mimes wireless communication architecture, enabling heat alarm points to be installed without traditional signal cabling.

RadioHeat 125 is designed for applications where cable installation is costly, difficult, or impractical. The detector enables fast deployment of heat detection points in industrial plants, offshore installations, utility areas, process facilities, machinery spaces, and other demanding environments where reliable temperature-based alarm detection is required.

The solution can be operated from an intrinsically safe battery supply using 7.2 VDC from 2 × C-cell batteries. In battery configuration, RadioHeat 125 is designed as an intrinsically safe Ex ia certified wireless heat detector, making it suitable for hazardous area applications where certified low-power field equipment is required. For industrial and non-battery applications, the unit may also be supplied from 24 VDC line power, enabling integration into standard industrial monitoring and control systems.

RadioHeat 125 is housed in a durable GRP enclosure, providing excellent corrosion resistance and long service life in harsh industrial, marine, offshore, and process environments. The compact and rugged design makes the detector suitable for both new installations and retrofit projects where wireless detection can reduce installation time, simplify installation, and reduce field cabling.

For safety-related applications, RadioHeat 125 can form part of a Mimes wireless safety architecture where heat detection signals are securely transferred to central control, alarm, or Fire & Gas systems. For standard industrial applications, the same platform provides a flexible wireless heat monitoring solution for equipment rooms, process skids, storage areas, machinery spaces, and remote field locations.
