The Kasi IR-120: Portable Infrared Asphalt Repair That Goes Where Trucks Can’t

When it comes to infrared asphalt repair, bigger isn’t always better—especially when the job calls for agility, speed, and access in tight spaces. That’s where the Kasi IR-120 shines. This walk-behind infrared heater delivers the same high-quality, permanent repair results as our larger units—just in a compact, go-anywhere package.

Whether you’re fixing a pothole on a residential street, patching utility cuts in a tight alley, or chasing birdbaths in a parking lot, the IR-120 gives your crew the power to get in, get out, and get it done—without the truck.

Built for Tight Spots & Quick Fixes

The IR-120 features a 3' x 4' heating chamber, delivering 12 square feet of consistent, even heat across the surface. That’s more than enough to handle most small-to-medium repairs in one heat cycle, with zero cold joints and no need for saw cuts or milling.

It's perfect for crews looking to extend their reach and reduce the overhead tied to larger units.

Key Features:

• 3' x 4' Infrared Heating Chamber Heats asphalt 1.5"–2" deep in just minutes for fast, efficient patching.

• Walk-Behind, Lightweight Design Maneuvers easily on sidewalks, alleys, trails, and tight urban environments.

• Propane Powered Simple and reliable fuel source—no need for generators or complex electronics.

• Quick Heat Cycles Most patches are ready to rake, lute, and compact in under 10 minutes.

• Durable Construction, Simple Controls Rugged frame and intuitive operation make it ideal for crews of all experience levels.

Who Is the IR-120 Made For?

• Municipal Crews — Perfect for residential streets, trails, and parks.

• Utility Contractors — Knock out service cuts quickly and cleanly.

• Airports, Campuses & Facilities — Navigate restricted zones with ease.

Permanent Repairs, Anywhere You Need Them

Like all Kasi infrared systems, the IR-120 softens the existing asphalt and blends in fresh material—creating a thermal bond that’s seamless, watertight, and built to last. It’s not a surface patch—it’s true asphalt restoration.

If you’re used to cold patch or cut-and-replace, this is your wake-up call.
