Advantages of Fenwal Heat Detectors
Precise activation
Using a rate compensation method, Fenwal heat detectors detect a rise in air temperature during both fast-rate and slow-rate fires, offering advantages over fixed-temperature or rate-of-rise devices.

Multiple applications
Suitable for oil and gas facilities, food production facilites, service stations, commercial and public premises and fast food outlets.

Options for optimal mounting
Heat detectors can be provided with a double thread or extended wire length to achieve the optimal mounting position and a Flurocarbon protective coating can be applied for use in corrosive environments (like spray booths).

Trusted Design
Repeatable and testable operation with a self-restoring action for long-term reliance.- Factory-set fixed activation temperature settings between 60°C and 385°C.
- Robust construction from durable stainless steel and no replaceable parts.
- Hermetically sealed and tamperproof design.
- Shock and vibration resistant
Accurate Operation
Precisely detects rise in air temperature during both first rate and slow-rate fires- Rate compensation method used to ensure activation at the pre-determined set point.
- Rapid response time during fast-rate fire.
- No false alarms from any brief and harmless rises in ambient temperature.
