Fan-Cooled Hydraulic Oil Coolers

About the product

In a hydraulic system, friction in the pump, valves and cylinders heats the oil. When the oil overheats, its flow behavior and lubricating function change, and system efficiency drops. A fan-cooled oil cooler passes the hot oil through a coil with channels and fins, while the integrated fan blows air across the fins. The air never touches the oil, and cooling takes place through heat transfer alone.

For a detailed look at the operating principle, see our article on cooling in hydraulic systems and how a radiator works.

The wide model range, with cooling capacity from 2500 to 40000 kcal/h, aims to meet different needs from small hydraulic units to high flow rate systems. Because the voltage type (DC or AC) and the model group (SF14-2010 ... SF72-2070) can be chosen separately, there is flexibility in both supply and capacity.

Where it is used

It can be used in hydraulic power units, in machines and equipment with a hydraulic circuit, and wherever oil temperature has to be controlled. DC models suit battery-powered mobile equipment, while AC models suit stationary facilities with mains electricity. For an overview of the model family, the article on fan-cooled oil cooler models is helpful.

Technical summary

• 18 model groups: from SF14-2010 to SF72-2070
• Every group with DC (12 V, 24 V) and AC (220 V, 380 V) options
• Maximum flow rate: 40-220 L/min
• Cooling capacity: 2500-40000 kcal/h
• Fan diameter: 200-630 mm; large DC models use 2 or 4 fans of 280 mm diameter
• Maximum working pressure: 15 bar
• Test pressure: 24 bar
• PDF datasheet for every model group

Choosing the right model

Model selection depends on flow rate, the heat to be removed and the supply voltage. Please prepare the following information for a quote or technical support:

• Flow rate of the hydraulic pump (L/min) and system pressure
• Oil tank volume and your target oil temperature
• Current oil temperature and ambient temperature
• Supply: DC 12 V, DC 24 V, AC 220 V or AC 380 V
• Connection size and the space reserved for the cooler
• Operating environment and duty (continuous or intermittent)

If you are unsure about the values, it is enough to send us the label data of the machine or hydraulic unit. Reading about why oil cooling systems are necessary can also guide you at this stage.

Pressure values matter in selection too: the working pressure of your system must not exceed the maximum working pressure of the cooler. If sudden pressure spikes occur in the hydraulic line, let us know. If you have it, please also share the type of hydraulic oil you use.
