Our closed circuit fluid coolers deliver reliable, low-maintenance heat rejection for industrial processes, data centers, and manufacturing. Featuring corrosion-resistant coils, variable-speed fans, and closed-loop design, they prevent contamination, reduce water usage, and ensure stable cooling for pumps, compressors, and hydraulic systems. Ideal for heavy-duty, 24/7 operations with long service life.
l Compatible with various environments: It can meet the requirements of different working conditions such as salt fog corrosion in the seaside, polluted environment, and high-temperature environment.
l Materials and craftsmanship: Our frame is made of 2 - 20mm steel plates bent, and the materials can be selected from stainless steel and carbon steel. Powder coating treatment is supported; The heat dissipation fins come in types such as pure aluminum without coating, aluminum-plastic sheet with clear water coating, and epoxy resin coating, etc. The selection can be based on the environment (such as rain, desert, seaside saline-alkali land), and the engineers will provide professional selection plans.
l Additional protection: Use weather-resistant and explosion-proof type cables and explosion-proof junction boxes. Support protection levels such as IP55, IP56, and IP65, which can meet the special requirements of chemical explosion-proof and other scenarios.
Power range | The power of a single device covers from 10 kilowatts to 5000 kilowatts (a 5000-kilowatt device is approximately the size of a 40-foot container). |
Noise control | Standard version: 80 decibels at 1 meter, 110 decibels within a 1 - 100 meter range; Low-noise version: 40 decibels at 10 meters, suitable for residential areas, beside residences, etc., where noise requirements are high. |
Adaptability | Capable of coping with temperature fluctuations and sudden changes in computing power load. In extreme high temperatures or when the load increases, it can cool down by spraying water and mist, quickly reducing the air temperature entering the heat exchanger, ensuring the equipment operates. |
Redundancy design | Utilizes a five-unit (total 10 units) design, with a 20% redundancy reserved (4 units are sufficient for operation), and one failure can be quickly switched to the backup group, enabling maintenance and replacement without downtime, meeting the requirements of high server continuity in scenarios such as remote medical care and logistics robots. |
l Capacity Assurance: The current workshop can assemble 30 units simultaneously, with a monthly production capacity of 200 container-type units and 400 cores. After the new workshop is completed in 2026, it will be able to assemble 100 units simultaneously. The monthly production capacity will further increase, meeting the demands of large customers for batch orders.
l Inventory and Supply Chain: We have 50 tons of copper tubes and 70 tons of stainless steel tubes as regular supplies. The suppliers of spare parts are all within 200 kilometers, ensuring stable supply of raw materials.
l Equipment and Team: We have 40 production equipment (each type of functional equipment has no less than 7 units), 200 workers, and 20 engineers. This enables us to avoid equipment failures affecting production and ensure stable supply throughout the year.
l 1-Year Warranty – Every dry cooler is backed by a 1-year warranty, ensuring long-term reliability and peace of mind.
l Fast Delivery – Standard models in stock can be shipped within 24 hours, reducing downtime for your operations.
l Customized Solutions – We provide tailor-made cooling systems to meet the exact requirements of your engines and working environments.
At SINRUI, every dry cooler is manufactured in our modern workshop with strict process control. From precision copper tube forming and fin assembly to high-strength frame welding, each step follows international standards to ensure durability and performance.
Our factory is ISO 9001 certified, and every unit undergoes rigorous leak testing, pressure testing, and thermal performance verification before delivery. This guarantees that customers receive radiators with consistent quality, long service life, and reliable cooling efficiency.
