Air Cooled (air-to-oil)

Keep Temperature Down to Help Ensure Your Oil and Other Components Last Longer.

Several different types of coolers are suitable for hydraulic systems, with air and water cooled being the most common.

Air-cooled systems dissipate heat with flowing air. This type of cooler operates by forcing cold air over hot fluid inside a heat exchanger’s coil or core. Low running cost and simple maintenance are attractive benefits of air-cooled systems. They also eliminate water-contamination problems and minimize corrosion. Additionally, heat generated from air-cooled systems can be used for other purposes

Oil-to-air (or air) coolers operate in the same way as the radiator on automobiles. The hydraulic fluid is directed through a series of small tubes to provide a large area for heat dissipation. Air is forced across the tubes, usually by a fan or a blower. All the conditions that are factors in the effectiveness of water coolers also apply to air coolers.

The heat differential is often a problem, especially in units that are outdoors. Because the air temperature usually depends on the time of the day as well as the season, the heat dissipation capacity of these units can be quite inconsistent. Air coolers are generally limited to applications in which the desired fluid temperature is at least 10°F (5.6°C) above the air temperature.

GS Global Resources offers a wide selection of air oil coolers, and radiators from well-known brands include both AC and DC, hydraulic, and engine driven fans. In addition to standard coolers, GS Global Resources works with OEM’s to engineer integrated Engineered Solutions to meet your specific needs.
