RZS-CB-3500
![]() | 1. Dual heating modes & on-site old material recycling for all-weather operation Two heating options are available: 220V mains power heating or diesel burner thermal-oil indirect heating. Operators can switch modes easily via control panel. It can heat cold asphalt mixture and keep hot mixture at working temperature. Old asphalt can be recycled on-site to cut raw-material cost. Even in cold winter or emergency rush repair, it guarantees normal road maintenance, perfect for municipal minor repair and highway medium maintenance projects. 2. Intelligent integrated control system with automatic fault alarm Central control panel monitors material tank temperature and heating status. Indicator lights and alarm lamps support quick fault diagnosis for operators. Dual-limit digital temperature controller plus mechanical over-temperature protection prevent overheating risk. 3. Zoned thermal-oil flexible heating, avoid asphalt aging & burning Thermal oil serves as heating medium. Zoned tank design enables simultaneous internal-external heating with large contact area. Uniform flexible heating prevents local overheating, burning and aging of asphalt mix. One-piece insulated tank keeps good thermal performance. Normal-temperature asphalt mixture can reach working temperature 140-160℃ within 3-4 hours. Material tank gate is driven by electric push rod for easy opening & closing. 4. High-efficiency screw discharging system with stable output Reducer drives screw conveyor for material discharging. Output capacity reaches 3 cubic meters per 15 minutes with stable feeding and low clog risk. Hydraulic motor drives auto-unloading mechanism. The equipment can be mounted on trucks with loading capacity above 6 tons for quick transit between working sites. 5. Complete night-construction safety configuration for high-traffic road repair Equipped with LED work lamp for night-time lighting. LED warning arrow lights provide over 200-meter visible distance to warn passing vehicles. Built-in power outlet supplies electricity for external power tools. 15-HP air-cooled electric start diesel engine serves as auxiliary power source for sites without mains electricity supply. |

![]() | The heating system has the functions of cold material heating and hot material insulation. Depending on the construction site conditions, it can use 220V mains power or use a burner to burn thermal oil for indirect heating. The heating method conversion can be easily completed on the panel; This device can ensure that under no circumstances will it be unable to be repaired on the road due to the asphalt mixture. At the same time, it can recycle old materials on site, maximizing the savings of raw materials and costs. It has excellent effects on minor and medium repairs of the road surface. |
![]() | Intelligent integrated control system. Centralize the control of heating material box temperature and box heating on the panel, and have indicator lights and alarm lights to diagnose faults. |
![]() | Adopting indirect heating method with thermal oil and fully automatic temperature control system with thermal oil, it is easy to operate and maintain, has low usage cost, and has strong adaptability to the environment. |
![]() | The box adopts an integrated insulation design with good insulation effect and high heating efficiency. It takes about 3-4 hours to heat the entire box of asphalt mixture at room temperature to 140-160 ℃. The electric push rod controls the opening and closing of the material box door. |
![]() | The asphalt paving machinery bitumen hot box uses thermal oil as the heating medium, with flexible heating and a large heating area at the same time to avoid burning and aging of asphalt materials. The box body adopts a zoning design to achieve simultaneous heating inside and outside, saving heating time. |
![]() | The asphalt mixture heating Insulation box equipped with dedicated LED construction lighting to meet the needs of night construction on road sections with high traffic flow. And it also equipped with LED safety warning lights, with an effective visual range of over 200 meters. It can effectively remind incoming vehicles to avoid during nighttime construction. |
