Product DescriptionThe DXD series consists of small, compact, and economical air-cooled hydraulic oil coolers. Featuring a compact design, simple construction, and flexible installation options, these units offer high efficiency at low flow rates and excellent value for money. They are specifically designed for standard hydraulic systems with medium to low power requirements and limited installation space.
Key Features & Technical Specifications
- Compact and space-saving design, ideal for tight installation spaces
- High-density aluminum finned core ensures stable cooling efficiency even at low flow rates
- Standard mounting holes support various installation orientations, including top, side, and vertical mounting
- Low-noise axial fan with smooth operation and long service life
- Integrated vacuum brazing process ensures excellent sealing and prevents oil seepage or leakage
- Cost-effective and high value for money, suitable as a universal replacement for small- to medium-power hydraulic systems
Applications Small hydraulic power units, woodworking machinery, small CNC machine tools, custom automation equipment, auxiliary machinery for light industry, small conveying machinery, injection molding peripheral equipment, and standard hydraulic systems for low-to-medium power applications.

- Rigorous Testing: Every DXF unit undergoes high-pressure leakage and performance testing to ensure zero-failure operation.
Product FAQsQ1:Is the DXD suitable for 24/7 continuous operation?A1:Suitable for continuous daytime production in factories and intermittent heavy-duty applications; for 24/7 high-load operations in high-temperature environments, we recommend upgrading to the DXB or DXG series for greater reliability.
Q2:What is the difference between DXD and DXB? How do I choose between them?
A2:DXD: Small, compact, and designed for lower flow rates; suitable for 0.4–15 kW hydraulic systems and applications with limited space.
DXB: Standard industrial model with higher flow rates and ample cooling capacity; suitable for 15–45 kW conventional machine tools and hydraulic power units.
Choose DXD for applications with limited space and low flow rates; choose DXB for slightly higher power requirements or when additional cooling capacity is needed.
Q3:Is the DXD difficult to install and maintain? Is it prone to oil leaks?
A3:It features a minimalist design with standard oil ports (G1/2–G1) and supports upright, inverted, or side-mounted installation. The fully vacuum-brazed core eliminates the risk of leaks at brazed joints, making it virtually maintenance-free and resistant to oil leaks when installed and used properly.
Q4:Can I customize the fan voltage for specific regions?
A4:Absolutely. We provide customized motor configurations (Voltage/Frequency) tailored to your local power grid standards.
