Project Overview
In March 2024, ZOOMLINE’s 4-6 t/h (ZAM-4 model) bitumen melting equipment installation and commissioning had been completed at the client’s construction site in the Republic of the Congo, and it was successfully put into operation. The project adopted the locally standard 380V/50Hz voltage and frequency, perfectly adapting to the local power supply conditions in the Republic of the Congo. Since production began, the equipment has operated stably and met production capacity targets, fully satisfying the client’s asphalt melting needs for road construction projects.
The project’s greatest core advantages lie in two key service and achievement highlights, which also constitute the core competitiveness of this overseas implementation: First, we assembled a dedicated professional overseas installation and commissioning team to travel to the construction site in the Republic of the Congo, providing the client with end-to-end on-site guidance, hands-on installation training, systematic equipment commissioning, and other one-on-one implementation services; Second, leveraging the team’s extensive overseas construction experience and standardized operating procedures, this project achieved rapid commissioning and production. The overall project timeline was significantly ahead of schedule, with all construction acceptance procedures completed ahead of schedule, allowing the equipment to smoothly transition to routine mass production.
Thanks to our professional on-site services and project outcomes that exceeded expectations, the performance of our bitumen melting equipment and the quality of our services have earned comprehensive recognition and high praise from our Congolese client.
The Congolese client involved in this collaboration has deep roots in the local road infrastructure sector. As local municipal road and highway renovation projects continue to advance, the client urgently needed a set of efficient, stable, energy-efficient, and environmentally friendly automated bitumen drum decanter to replace traditional, outdated equipment and ensure construction progress and production efficiency.
Prior to equipment procurement and implementation, the client faced numerous challenging project issues and construction difficulties: Traditional asphalt melting machine generally suffers from high labor intensity, low melting efficiency, and severe environmental pollution, making it unsuitable for modern engineering production needs. At the same time, local construction teams in the Congo lacked professional experience in the installation, commissioning, and operation and maintenance of automated continuous bitumen melting equipment. Their unfamiliarity with systematic equipment operating procedures posed numerous risks, including installation errors, commissioning failures, and production start-up delays.
Therefore, the client’s core requirement for this procurement is not only to acquire high-quality bitumen drum decanter but also, more urgently, to secure one-stop professional on-site technical support from the manufacturer. This support is essential to thoroughly resolve on-site construction challenges, ensuring rapid equipment installation, stable commissioning, and swift start-up, thereby guaranteeing the project’s on-schedule progress.
Given the actual conditions at the local construction site in the Congo, this project’s implementation faces multiple practical challenges:
On the one hand, the local infrastructure construction schedule is tight with strict project milestones; the commissioning time of the asphalt melting equipment directly impacts the overall road project progress, placing extremely high demands on project delivery efficiency. On the other hand, there is a shortage of local technical personnel, and construction workers lack understanding of the structural principles, installation standards, and system commissioning procedures for the new continuous bitumen decanter, making independent on-site implementation extremely difficult. Furthermore, the complex tropical construction environment in Africa places higher demands on equipment adaptability and on-site construction expertise.
To address these numerous project challenges, ZOOMLINE developed a tailored overseas implementation solution, with the core measure being the deployment of a dedicated professional team to provide on-site, end-to-end support:
ZOOMLINE selected a team of engineers with extensive overseas project experience to be stationed at the construction site in the Congo, where they provided on-site support throughout the entire project implementation process. From the positioning of the drummed-bitumen melting equipment upon arrival, assembly of the main structure, and installation of the drum-feeding mechanism, to the precise commissioning of the direct-fired fuel system, thermal oil circulation system, and asphalt pumping system, and on to technical training for on-site operators—we provide one-on-one professional guidance throughout the entire process. This enables us to precisely resolve all technical challenges encountered by the client on-site and avoid various issues such as installation deviations, system failures, and commissioning errors.
Leveraging the team’s standardized operating procedures, extensive overseas construction experience, and meticulous on-site management, we efficiently advanced all construction tasks, successfully overcame on-site challenges, and ultimately achieved rapid project delivery—far exceeding the client’s expected construction schedule—thereby successfully resolving the client’s core challenges of tight deadlines and technical gaps.
The ZAM-4 4–6 t/h drummed bitumen melting system deployed for this project in the Democratic Republic of the Congo is a continuous asphalt melting system independently developed by ZOOMLINE, specifically tailored for road infrastructure projects. The equipment integrates five core components: the main unit, the drum-loading and feeding mechanism, the direct fuel heating system, the thermal oil circulation system, and the bitumen pumping system. Each module is rationally laid out, operates independently, and works in coordination, ensuring exceptional structural stability.
The unit employs fuel-fired direct-heating continuous melting technology, combined with a sealed thermal oil circulation system, to maximize thermal energy utilization, significantly improve bitumen melting efficiency and thermal energy efficiency, and effectively reduce energy consumption during production. At the same time, it thoroughly addresses the industry pain points associated with traditional bitumen melting equipment—such as high labor costs, low production efficiency, and severe environmental pollution. It offers advantages including high efficiency, energy savings, environmental friendliness, stable operation, and convenient maintenance. Highly suited to Africa’s complex construction environments and medium- to long-term mass production needs, it is the preferred equipment for overseas road infrastructure projects.
Unlike the conventional industry model of merely supplying equipment without on-site implementation services, ZOOMLINE provides overseas clients with a full-cycle, closed-loop on-site service covering everything from preliminary coordination, on-site construction, and commissioning to technical training. This is the core guarantee for the efficient implementation and rapid commissioning of this project, with a complete service process that is standardized and professional.
Our on-site engineers conduct preliminary site surveys in advance. Based on the local construction environment, electrical standards, and site conditions in the Democratic Republic of the Congo, they develop a customized installation and commissioning plan to proactively address potential issues such as site compatibility and electrical system adaptation, thereby laying a solid foundation for the project’s efficient progress.
The team carried out end-to-end on-site supervision, closely monitoring core processes such as the assembly of the main equipment, calibration of the drum-feeding mechanism, integration of the heating and circulation systems, and commissioning of the pumping system. They corrected any deviations in real time to ensure installation precision and guarantee the stable, coordinated operation of all systems.
Concurrently with installation and commissioning, engineers conduct systematic technical training for the client’s on-site operators. Through hands-on instruction, they teach core skills such as daily equipment operation, parameter adjustment, maintenance, and troubleshooting common faults, ensuring the client’s team can operate the equipment independently, in accordance with standards, and consistently, thereby guaranteeing long-term, stable operation.
The fully standardized and refined service process thoroughly avoids schedule delays caused by repeated commissioning, rework, and operational errors. Ultimately, this Congo project completed all acceptance procedures with exceptionally high commissioning efficiency, significantly ahead of the original construction schedule, and the bitumen melting equipment has successfully entered a stable mass production phase.
To visually demonstrate the implementation results of this Congo bitumen melting project and our professional service capabilities, we have compiled a video featuring actual footage from the construction site throughout the project. The video comprehensively documents the entire process—from our engineers providing on-site installation guidance and systematic equipment commissioning to the trial operation and production launch—faithfully recreating the on-site implementation of this overseas project.
The video clearly demonstrates that our team adhered to standard operating procedures and displayed technical expertise, ensuring high precision in equipment installation and smooth commissioning. Following production launch, the system operated stably with uniform output, fully meeting the client’s mass production standards. This video serves as the most direct evidence of our overseas on-site service capabilities, equipment stability, and rapid delivery capacity, comprehensively enhancing the trust of our overseas clients.
Following meticulous installation and commissioning by our professional team, this 4–6 t/h bitumen melting system has achieved stable production at the construction site in the Congo. It has maintained steady long-term operation and met production capacity targets, perfectly aligning with the client’s daily bitumen melting and production needs. The system provides robust equipment support for the steady progress of local road infrastructure projects, effectively helping the client improve construction efficiency and shorten project timelines.
