Very High Temperatures (VHT)
ProReact VHT Linear Heat Detection for High-Temperature Environments. Reliable Fire Detection Where Heat is Constant and Risk is High.
Industrial environments with sustained high temperatures – such as engine bays, commercial kitchens, and process plants present extreme challenges for fire detection. Conventional systems often fail or trigger false alarms due to ambient heat and humidity.
ProReact VHT LHD is engineered to perform where others cannot. With an alarm activation temperature of 230°C and a maximum ambient temperature of 170°C, it delivers dependable protection in the harshest conditions.
UL & FM Approved System for Very High Temperatures
ProReact Very High Temperature (VHT)
Extreme heat? ProReact VHT delivers reliable protection, with activation at 230°C.
- UL and FM approved
- Continuous operation up to 170°C
- Optional stainless steel braiding for mechanical protection
Why Fire Detection in High-Temperature Areas is Challenging
- Extreme Ambient Heat
Many detectors distinguish between normal operating temperatures and actual fire events. - Contaminants
Grease, dust, steam, and high humidity interfere with traditional spot detectors. - Limited Access
Maintenance in confined or hazardous zones is difficult and often dangerous. - False Alarms
High ambient temperatures can cause conventional systems to set off, disrupting operations.
