What Other Customers Say:
“We’re working on a project at the Super Walmart in Charleston South Carolina, and I just wanted to take a minute and let you know how impressed I am with this little infrared machine. We are currently using it as part of a larger project we have underway here. There was some patching and Walmart Management had some concerns about possible trip hazards up near the building. Were using our little infrared machine to take down those trip hazards rework that asphalt and make it seamless where it joins the existing asphalt right up by the building to eliminate the trip hazards. This is a great little machine and I look forward to getting a bigger machine for bigger projects. I’ll send you some photos. All the best!“

How does this portable infrared asphalt heater work?
The RY2X2 Infrared Asphalt Heater is easy to use. Simply place it over the distressed asphalt point, light the self-contained burner, and in as little as five to 10 minutes, this heater will have the asphalt brought back to its original mixing temperature. Remove the machine, rake the asphalt into place, compact the asphalt with a vibrating plate or plate compactor, and you're all done!
In the past, you'd have to drive to the asphalt plant, buy new asphalt, dig up the old asphalt, replace it, and then figure out where to dispose of the old asphalt . . . all of those steps are eliminated now! Just wheel the portable infrared asphalt heater into place, light it, and you're halfway done! The unit weighs just 90lbs and features heat-shielded caster wheels, so you can operate it with just one person – no crew needed to move it around.
This infrared asphalt repair equipment is built to last: the frame is 11 gauge steel, and the stainless steel and ceramic heater cartridge has an average lifespan of 1,500 hours.
The RY2X2 asphalt heating machine uses actual infrared heating (not blue flame heating) through a ceramic mesh cartridge. This provides the best heat distribution of any infrared heater for asphalt in its class.
Like all RynoWorx products, this unit puts safety first. No open torch flame that can blow out or leak propane on the job. And the regulator with a built-in pressure gauge means you always know how much fuel is flowing so you can turn the heater temperature up or down.
How can you make money with this? You can do asphalt repairs all year-round, but especially for emergency winter pothole repair.

Can You Reheat Over Oil Spots? Use the Key Test First
Before using the R4 Infrared Heater on any asphalt surface that shows signs of oil or grease, it's crucial to check the integrity of the asphalt. Reheating soft or compromised pavement can lead to failure. Use this quick jobsite test to know what you're working with:
The Key Test
- Press a key or screwdriver into the oil spot or stained area.
- If it sinks in or feels soft: The base is likely damaged. Heating won’t help. You’ll need to remove and patch instead.
- If it stays solid: You're good. Hot pressure wash or degrease the area, let it dry, and proceed with infrared heating.
This step ensures proper bonding, protects your heater investment, and gives your repair a longer life—especially when working on gas station lots, high-traffic commercial zones, or heavily stained pavement.
Storage & Handling
- Allow unit to fully cool before storing
- Store in an upright position in a dry location
- Disconnect propane tank after use
- Replace ceramic cartridges as needed
