OR Series Oil Coolers
Product Introduction
1. Employs bare tube (unfinished surface) heat transfer tubes, resulting in a high external film heat transfer coefficient and strong anti-fouling ability.

2. The heat transfer tubes are made of pure copper with a thermal conductivity of over 0.95, ensuring excellent heat transfer performance.

3. The cooler uses a multi-tube design, providing a large cooling area and excellent heat exchange effect.

4. Utilizes advanced expansion joint sealing technology, overcoming adverse changes in materials after high-temperature welding, resulting in superior and stable performance.

5. A complete product series with various sizes and specifications. Stainless steel inner liner series can be derived to meet different needs.

*Complete product series with various sizes and specifications. We can derive stainless steel inner tank series according to different customer needs.

※The cooler’s inlet oil pressure is less than 1 MPa, oil temperature is below 70°C, inlet water pressure is less than 0.5 MPa, temperature is below 30°C, oil viscosity is less than 50 cst, and oil-water flow ratio is 1.5 times. Under these working conditions, the oil temperature drop is greater than 8°C, and the heat exchange coefficient is greater than 300 kcal/m2.h.°C.
