Zoomlion LR4500 Heater has efficient, speedy and uniform heating, flexible temperature control, and advantages of energy saving and environmental protection, suitable for asphalt and concrete road surface on site heat regenerating project for high level road, civil road, and airport runway.

LR4500 Heater is an equipment for massive and continuous heating in asphalt and concrete road surface on site heat regenerate project, to make asphalt and concrete road surface in certain depth to the required temperature needed for harrow, mix and pave by remixer. Efficiently withstand the violation to the asphalt road surface from sunshine, rain, and oxidation, and solve the problem of dry, fragile, loose and craze.

Suitable for asphalt and concrete road surface on site heat regeneration project for high level road, civil road and airport runway.

Suitable for roadbed pre-heating project for asphalt and concrete paving in winter.

Suitable for relieve ice on the surface of the road, airport runway and bridge in north cold area.

Satisfy requirements of better quality and less cost.

Suitable for trends of more loading and more environmental protection.

From 1974, on site heat regenerate equipment is an usual equipment in the world.

Heat efficiency, speedy heating, less fuel, and flexible for temperature control.

Hot air stove and hot air cycle system.

The hot air cycle system consists of high loading and high efficient hot air stove and cycle air mechanism, comparing to other heating method, has the advantages of compact structure, speedy and even heating, and efficiency. Due to adoption of hot air recycle, the heat energy could be used again and again, saving 30% fuel than other heating method.

Burning Mechanism and Temperature Control System

The burnable compound mixed with fuel and air, burned in the high performance and large range adjusting Burning Mechanism, and born hot air. The temperature control system, consists of microprocessor from Finland and adjustor from USA, will automatically control the burning according to the set temperature, realize the temperature auto-control, accurate and reliable.

Green, almost no affection to the environment, almost 100% resource utilization.

The Hot Air Stove and Hot Air Cycle System, no fire, no smoke, no pollution, create better environment for the operator and the project, makes the work more speedy, and no need for close working. Less vibration noise, even able to work at night or in the downtown without interruption to the citizen.

Two energy saving advantages: First, saving 30% asphalt compound cost, 400 tons asphalt consumption for high-speed four driveway per kilometer, on site regenerating, 100% recycle for the compound from the old road; Second, saving transportation fee and place charge, no need for refuse transportation and place for refuse.

Two new image, extend 20 years life limitation of the asphalt road surface, road surface regenerated as brand new.

Break the image of mend, even hearting combines the pave section of the crack with the original road surface perfectly, new road surface has the same quality like the original road surface.

Heating Mechanism

Deliver the hot air to the heating mechanism, this heating mechanism is a shell made with alloy steel anti-high-temperature, receive the hot air form the Hot Air Stove, and evenly distribute the air to the air tunnels and radiation surface inside of the shell. The radiation surface will deliver the heat energy to the asphalt road surface, and the hot air will convert heat energy with the asphalt road surface through the tunnel. Through control on the hydraulic cylinder, the heating mechanism could easily adjust the heating width and height.

Speedy, one day's work with the new technology equals to several days' work with old technology. One regenerator could finished 5000m2 per day.

Power system and Hydraulic system

Adopting DEUTZ original motor from Germany, strong power, meeting the emission requirement from Europe Environmental Protection Standard.
