Trackless Electric Infrared Asphalt Heater
Trackless Vehicles Ltd.
The Infrared Asphalt Heater attachment from Trackless Vehicles Ltd. is operated with an 80-hp generator, compared to traditional propane asphalt heaters, and it produces 45 kw and 175 amp. When the asphalt heater isn't in use it can be separated from the generator frame in less than 5 minutes. As a result, the 110-volt and 220-volt receptacles can be used to power welders, pumping stations, and other equipment or tools. With a heating pan area of 4 feet x 6 feet, the unit has 11 heating elements. The Infrared Asphalt Heater produces an even and controlled heat without an open flame and will not burn the surface. Another feature is the controlled cycle times allowing contractors to establish their optimum cycle time for the jobsite conditions. Because of the way it’s designed and the fact that it’s an attachment, the unit does not require a license for changing propane tanks, and eliminates the possibility of leaking valves or fuel tank ruptures. Also, there is no open flame near a fuel tank, nor is there an open flame over or near catch basins or manholes. The small size of the unit also allows contractors to precisely position the infrared heater.
With several available units, KM International offers contractors a variety of portable and trailer-hitched infrared asphalt heaters. One unit, the KM2-18X Infrared, is lightweight and easily moved to areas previously inaccessible by larger infrared equipment. Operating using two 30-pound cylinders of propane, it consumes 12 pounds of propane per hour. The KM2-18X Infrared uses a 1-inch ceramic blanket featuring convection/conduction heat for an even transfer of heat. The unit has 300,000 BTUs and has a 12-volt DC-powered blower. Operators have the option to use a single 3-foot, 6-inch x 3-foot, 3-inch zone or dual 3-foot, 6-inch x 6-foot, 6-inch zones totaling 22.75 square feet of infrared heat. The KM2-18X Infrared also works for thermoplastic template applications. Contractors can use this unit for small pothole repairs, emergency repairs and joint repairs. Additional units available from KM International include LB2-16 Portable Infrared Asphalt Heater, KM4-40, KM4-48 and KM4-20.
Thermotrack has several available products for stamped asphalt including coatings, grid patterns and an infrared heating system. The Accu-Therm Infrared, a reciprocating infrared heater, focuses on precision heating ability, adjustment capability and mobility. The electric-powered, belt-driven, non-stationary infrared heating elements travel back and forth on a rounded rail track for deep heating without surface damage. It can heat an area up to 58.5 square feet, and the element baffles deflect and focus the infrared heat downward preventing heat from rising. The graduated heating process allows for each pass over the asphalt to increase temperature and penetration. The unit's heating elements are constructed of stainless steel and wire mesh.
Asphalt Reheat Systems
Among Asphalt Reheat Systems available units are portable heaters, trailer heaters and seam (or joint) heaters. The 4x4 heater is one of several portable heater options. Available with a standard high-output heating area of 16 square feet, the unit weighs 195 pounds and measures 60 inches x 65 inches x 39 inches. Three heating options are available including a split channel with 2-foot x 4-foot areas, a high-output heating 4-foot x 4-foot areas, and pinning two units together to heat a 4-foot x 8-foot area. When pinning the two units together, contractors connect the units with a bracket but still operate it with a single control. The 4 x 4 has low fuel consumption with up to 3 hours of operation per 20-pound propane tank. The unit can reheat almost any asphalt to a pliable texture in less than 5 minutes, and it can be used to repair both small and mid-size areas. In the split channel version the operator has the option of heating one half the unit at a time, and changing which side receives the heat is done by flipping a switch on the handle.
