DC Oil CoolersCompact, efficient transmission cooling
Compact design
The dc oil cooler features a space-efficient design that integrates seamlessly into both new installations and existing systems where available space is limited. Leading dc oil cooler manufacturers have optimized these units to deliver maximum cooling capacity from minimal footprint.
Performance
This high-quality, fully sealed cooling system reliably handles oil pressures up to 30 bar with exceptional efficiency. Where other cooling solutions assembled from dissimilar materials often fail under pressure, these purpose-built units maintain consistent performance in demanding applications.
Shell & Tube Design
The DC utilizes a single-pass configuration with the tube stack permanently fixed within the outer shell. Specialized internal baffles create optimized flow patterns that extract remarkable heat transfer efficiency from such a compact unit.
Range
These versatile dc oil coolers offer four oil port size options plus three seawater pipe dimensions, available with either in-line or right-angle neoprene end covers. For specialized installations, units can be supplied without end covers for custom integration.
Durability
The brass outer shell features nickel plating for exceptional durability and aesthetic appeal. The tube stack incorporates premium 90/10 cupro-nickel tubes—the same high-performance material used in larger oil cooler systems. With hundreds of thousands of units in active service worldwide, these coolers have proven their reliability in demanding applications.
Easy to Maintain
Neoprene seawater connections install quickly and can be removed using only a screwdriver, simplifying routine cleaning and maintenance procedures while minimizing downtime.
Quality
As a trusted cooling solution manufactured in the UK for over three decades, the dc oil cooler has established itself through continuous performance in some of the world's most challenging operating environments and toughest applications.

FAQ'S
DC oil coolers are used to reduce the temperature of hydraulic or lubricating oil.
They are commonly used in heavy machinery, such as construction equipment, industrial presses, and agricultural vehicles.
DC oil coolers typically consist of a cooling core, a DC fan, and inlet and outlet ports.
The cooling core is often made of a finned tube or plate design, while the DC fan is powered by a direct current motor.
The working principle of a DC oil cooler involves the hot oil entering the cooler through the inlet port and flowing through the cooling core.
The heat from the oil is transferred to the surrounding fins, which are then cooled by the DC fan. The cooled oil exits the cooler through the outlet port.
