Need High-Output Heat Without a Permanent Installation? This 120,000 BTU Radiant Heater Brings Portable, Commercial-Grade Warmth Wherever the Job Takes You

Cold weather shouldn't slow your crew down. The SunFire SF120 Radiant Heater delivers 120,000 BTUs of powerful infrared heat, warming people, tools, and equipment directly instead of wasting energy heating the surrounding air. Whether you're working in a shop, garage, warehouse, or active jobsite, you'll feel the warmth where it matters most—even in large, drafty spaces.

Unlike noisy forced-air heaters that blow dust and lose heat every time a door opens, the SF120 provides quiet, directional heat that keeps work areas comfortable without creating unwanted airflow. It's an excellent solution for service bays, fabrication shops, loading docks, construction projects, and other commercial spaces where reliable temporary heat is essential.

Designed with portability in mind, the SF120 rolls easily between work areas and requires no permanent installation, gas piping, or major electrical service. Its dual-fuel capability lets you operate on diesel or kerosene, giving you the flexibility to use the fuel that's most convenient for your operation.

From protecting temperature-sensitive materials to improving worker comfort and productivity, the SunFire SF120 is built for professionals who need dependable, high-output heat in demanding environments. If you're looking for a radiant heater that combines power, portability, and efficiency, the SF120 is ready to get to work.
