Key Benefits That Drive Value

✅ Prevents Overheating & Downtime: Multi-tube construction (3x more cooling area than standard fin-tube models) rapidly dissipates heat, keeping hydraulic oil temperatures in safe ranges to avoid seal failures, component damage, and costly production halts.

✅ Quiet & Low-Maintenance: No moving parts or loud fans—operates silently, reducing workplace noise pollution. The closed design minimizes debris buildup, cutting down on cleaning and maintenance time.

✅ Durable & Versatile: Pure copper tubes (thermal conductivity of 0.95) ensure efficient heat transfer, while a rugged iron shell withstands vibration and harsh industrial environments. Rated for oil-side pressure up to 10 kg/cm² and water-side pressure up to 7 kg/cm².

✅ Wide Range of Sizes: Available in 9 models (OR-60,100,150,250,350,600,850,1000,1200) to match your system’s flow rate (60–1200 L/min) and space requirements. Standardized PT ports (3/4” to 2”) simplify installation, making it a drop-in solution for most hydraulic setups.

Ideal for Every Industry

• Manufacturing: Injection molding machines, hydraulic presses, and assembly lines.
• Construction: Excavators, loaders, cranes, and mobile hydraulic equipment.
• Industrial: Hydraulic power units, cooling stations, and custom machinery.
• Agriculture & Marine: Tractors, harvesters, and marine hydraulic systems.

Real-World Scenarios Where the OR Series work

• Manufacturing & Machinery: Your injection molding machine or hydraulic press works nonstop—oil temperatures spike, leading to seal failures and costly repairs. The OR Series’ shell-and-tube design (with pure copper tubes for maximum thermal conductivity) rapidly dissipates heat, maintaining oil temperatures within safe ranges to prevent breakdowns and extend machine lifespan.
• Construction & Heavy Equipment: You’re operating hydraulic excavators, loaders, or cranes in dusty, harsh environments. Unlike finned-tube coolers that clog easily, the OR Series’ closed-cylinder design thrives in dirty conditions—no more frequent cleaning or reduced airflow. Plus, its quiet operation won’t add to the noise pollution of job sites.
• Industrial Hydraulic Stations: Space is at a premium in your facility, and bulky cooling units take up valuable floor space. The OR Series’ compact, cost-effective design fits seamlessly into tight layouts without sacrificing cooling power—ideal for hydraulic stations, power units, or custom machinery setups.
• Mobile Hydraulic Systems: Whether it’s agricultural equipment, marine vessels, or mobile hydraulic tools, you need a cooling solution that’s durable and efficient. The OR Series’ robust iron shell and copper tube construction withstands vibration and extreme conditions, while its multi-tube design ensures maximum cooling area for reliable performance on the go.
