Hydraulic Oil Coolers


A hydraulic oil cooler is a device that is used to keep the hydraulic oil at a suitable temperature. This allows the oil to shed heat, reducing wear and tear on the components and maintaining proper viscosity. Coolers are typically used in hydraulic systems where there is high power input. If the oil becomes too hot, it can cause damage to the system components and increase maintenance and repair costs.

Coolers for hydraulic oil are available in various types and sizes to suit many applications. These include air-cooled, water-cooled, and fuel-cooled units. While these are the most common, there are other types that are designed specifically for hydraulic applications. Regardless of the type of coolant used, it is important to make sure that the temperature is correct.

When deciding on a cooler, consider the amount of input power and the continuous flow of the system. Using an arbitrary percentage of the input power, the size of the cooler can be calculated. Generally, if the system has a 100kW of continuous input power, the cooler should have a cooling capacity of at least 20kW. For temperatures above 200 deg C, an additional cooling capacity may be needed.

The design of a hydraulic oil cooler involves two main elements: the tubing and the shell. Tubes are made from cupronickel or other non-corrosive materials. Cupronickel has a surface area that is ideal for cooling hydraulic oil. Seals are usually made from nitrile, but they are also available in viton, ethylene propylene, or Viton.

The plumbing of a hydraulic oil cooler can be a little more complex than other types of cooling devices. Industrial air purifier In addition to the cooling medium, the return line needs to be considered. It is recommended that the return line has a modulating type of valve.

Hydraulic oil is a high-pressure fluid that is often subject to cavitation. This can cause particulates to form and damage the seals on the hydraulic component. To avoid this, it is important to install a hydraulic oil cooler that has a higher pressure than the water pressure. Additionally, it is recommended that the oil cooler be installed in the return pipe to the tank to prevent contamination with water.

Heat exchangers are another type of cooler used to help maintain the proper temperature of the hydraulic fluid. Some equipment manufacturers use air cooled heat exchangers, which do not require a power source. Others rely on brazed plate heat exchangers. Both types work by circulating the fluid through a special tube stack.

A cooler is not only a vital piece of equipment for your hydraulic system, it can be a useful tool for keeping your machinery operating at the highest efficiency. By maintaining the proper temperature, the hydraulic system can remain in top condition and extend its life. Oil coolers have a variety of features that are specific to the model, making it easy to find the right fit for your application.

Whether you are looking for a heat exchanger for hydraulic oils, quenching oils, or other liquids, Bowman can offer you a solution to your needs. They are manufactured in various configurations, including air-cooled, water-cooled, and air-to-air. Many of their units are available with computer-aided selection software, making it even easier to select the best option for your specific application.
