Recently, a batch of high-performance rooftop packaged units from Ruidong Group completed ocean shipping and were successfully delivered to the manufacturing workshop of a large industrial park in Mexico, providing a stable and energy-saving industrial temperature control system for the local precision production lines.
The rooftop units for this Mexican project are custom-designed units. Ruidong's solid customization capabilities laid the foundation for the smooth implementation of the project, while its strong manufacturing capabilities provide stable cooling for the manufacturing workshop throughout the year.
Location: Large integrated industrial park in Mexico
Requirements: Year-round cooling, providing stable cooling for multiple production lines throughout the year;
Environment:
Mexico experiences large temperature differences and high salt spray concentrations in some coastal areas, making ordinary air conditioning equipment highly susceptible to casing corrosion and component aging;
The equipment needs to undergo long-distance sea transport, placing stringent requirements on the structural stability of the unit and the protective packaging capabilities;
For this Mexico project, Ruidong customized rooftop packaged units adopt an integrated design, with the entire unit integrating refrigeration, air supply, and control modules. It can be directly installed on the factory roof without the need to build a separate indoor machine room, which greatly saves valuable production space in the workshop. At the same time, it simplifies the on-site pipeline connection process. Simply connect the pipes to achieve rapid on-site installation, which is perfect for the tight schedule of overseas factories and avoids construction pressure.
Leveraging years of experience in industrial HVAC R&D, the rooftop packaged units delivered by Ruidong this time are equipped with multiple industrial-grade technologies, making them fully adaptable to the complex industrial environments in Latin America:
Guaranteed all-weather, uninterrupted and stable operation: The unit adopts multiple redundant circuits and fan redundancy designs, with double backup of key components, which can support 24/7 continuous production in the workshop, prevent equipment shutdowns from causing production line interruptions, and ensure production safety.
Equipped with an intelligent frequency conversion control system: It can stably balance temperature fluctuations in the entire workshop, avoid precision workpiece processing errors caused by temperature difference deviations, and meet the strict process standards of high-end manufacturing.
Super weather-resistant and anti-corrosion design: The frame of the whole machine adopts thickened reinforced profiles, and the whole machine is sprayed with a special salt-spray-resistant anti-corrosion coating to resist the erosion of high humidity and salt spray along the coast of Mexico. It also adapts to the extreme climate of high temperature and drought in the interior, greatly extending the service life of the equipment overseas.
Integrated design: The integrated roof structure greatly reduces overseas on-site welding and wiring construction processes, shortening the on-site installation cycle; the unit is equipped with high-efficiency scroll compressor and VFD variable frequency drive technology, dynamically matching the workshop load, effectively reducing equipment operation energy consumption.
Customization: To match this project, the units exported are specially customized
The condenser features an epoxy resin anti-corrosion coating. The dense epoxy film isolates the unit from corrosive media such as high salt spray, high temperature and humidity, and industrial exhaust gases along the Mexican coast, preventing electrochemical corrosion of the metal and providing wear resistance, corrosion resistance, and anti-aging properties.
The unit structure has been optimized and its height reduced. To facilitate international transportation, the unit's height has been adjusted. Unlike previous models, the ultra-low unit height still provides a 105kW cooling capacity, significantly saving transportation and installation space.
Other advantages of Ruidong rooftop units
In addition to epoxy resin coating and structural optimization of the condenser, Ruidong rooftop packaged units can also be customized with variable frequency design, high and low pressure differential gauges, etc., to provide customized heating and cooling supply solutions for users in different regions.
High-efficiency components: Employs internationally renowned brand compressors and high-efficiency fan systems to improve energy efficiency ratio.
Low-noise centrifugal fan: Provides stable, high-volume airflow while reducing operating noise.
Ruidong's self-made aluminum fins: Aluminum fins with a hydrophilic coating.
Beautiful and corrosion-resistant casing: Constructed with galvanized steel sheet and lined with thermal insulation cotton to ensure corrosion resistance and extend service life.
Remote control: PLC and RS485 interfaces enable remote monitoring and control of the unit, facilitating operational monitoring.
Multiple protections: High and low voltage, overcurrent, and phase sequence protection functions.
Unit functions: Cooling-only and heat pump models available; voltage, power, air volume, and other functions can be customized.
For a long time, Ruidong has been continuously increasing its investment in the Mexican and surrounding Latin American markets, and has established a professional after-sales team to form a complete service chain from preliminary site surveys and solution customization to marine protection, on-site installation guidance, and subsequent operation and maintenance. It also provides a 1.5-year warranty service to ensure that each unit can better serve customers.
Facing the global wave of green industrial transformation, Ruidong will always take independent technological innovation as its core driving force, and focus on the research and development of product lines such as industrial rooftop units, large central air conditioning, and special temperature control equipment to create comfortable, low-carbon, and reliable indoor production climate environments for manufacturing enterprises around the world.
