STI HTR045T Radiant Heater 45W with Thermostat

Protect vital security and life-safety equipment from cold-related failures with the Safety Technology International STI HTR045T radiant heater. This enclosure heater with thermostat is engineered to maintain reliable operation of fire alarm and control panel systems, keeping internal temperatures near 40°F (4°C) even when ambient temps fall to −20°F (−29°C). With a modest 45W power rating and wide 110–250V compatibility, the HTR045T delivers efficient frost protection without adding significant electrical load.

The built-in thermostat automates on/off cycles to preserve energy while preventing condensation, sensor drift, and relay or circuit faults that can compromise surveillance, security and monitoring performance. Its radiant footprint mounts easily inside standard alarm/control enclosures and is recommended for use with EF121006-O, EF121006-W, EP121007-O and EP121007-T units for straightforward integration. Specify the STI HTR045T when you need dependable, low-power enclosure heating to extend equipment life and reduce nuisance alarms. Order today to add robust frost protection to your fire alarm and control panel installations.
