Industrial Hydraulic Coolers

Controlling the flow of pressured hydraulic fluids entails handling a hydraulic system. An Industrial Hydraulic Cooler is a device used to cool hydraulic oil, which is commonly seen in Hydraulic Power Packages. Nonetheless, they may be utilised on Power Washers, Engines, and nearly anything else that requires the cooling of hot oil. Oil coolers minimise the heat generated by hydraulic oil in both closed and open hydraulic systems by passing it through a coil or core. This cooling component can also help to reduce the impact on the environment. If the equipment is mobile, some manufacturers utilise an air-cooled heat exchanger; some use a brazed plate heat exchanger, but many opt for a standard shell and tube oil cooler. Hydraulic systems are susceptible to heat; therefore, hydraulic oil coolers are frequently utilised in agricultural, manufacturing, and industrial environments. Hydraulic coolers help increase efficiency by ensuring that the machinery is kept at the proper temperature. As a result, they increase the machine’s component lifespan by lowering the cost of maintenance and repairs. Oil coolers can be used in hydraulic systems in various ways, with air and water coolers being the most popular. This article will explain why hydraulic oil coolers are necessary, their benefits and the criteria for choosing the best hydraulic cooler. 

Elements of Industrial Hydraulic Coolers: 

  • Cooling fan, 
  • Oil reservoir
  • Radiator 
  • Hydraulic motor
  • Suction elbow and pipe kit After mounting
  • Filter / radiator bypass valve
  • Relief valve
  • Filter block indicator
  • Oil level sight glass

Benefits of using Hydraulic Coolers include:

Stable Cooling

You can get consistent cooling and filtering performance using a hydraulic oil cooler, regardless of the leading hydraulic circuit’s flow and duty cycle fluctuations. This also permits the coolers to be sized to match the heat load rather than the primary circuit’s maximum return flow. The fact that these coolers are fully isolated from the pressures in the return line, which may potentially harm it, is an even more significant plus. Additionally, filter maintenance can be conducted without shutting down the primary system.


Shell and Tube Oil Coolers are straightforward, with no moving parts and a proven design. As a result, the product is dependable. They are durable and have a long span, so one can easily invest their money into these products. 

Proper Greasing

High friction causes the equipment to wear out faster and lose its integrity, and therefore, appropriate oil viscosity is required to achieve optimal performance levels. The likelihood of friction is reduced when the machine’s components are adequately greased. The viscosity of a machine decreases as it heats up. The oil becomes thicker as the device cools.


Extruded shell coolers allow producers to deliver a broad range of choices without the tooling costs and extended lead times associated with model shell coolers. With enough pass types, each with multiple distinct threaded and hose tail connections, the headers, or end caps, also provide flexibility.

Ease of Service

One of the essential advantages of Industrial Hydraulic Oil Coolers is their ease of maintenance. You may access any component and change seals, headers, or the tube stack without using any additional tools by removing the four cap screws on either end of the cooler. A proper maintenance schedule can extend the life of an Oil Cooler by more than 15 years.

Selection Criteria

You must know the following points to size a cooler properly:

  • The quantity of heat that must be evacuated from the system.
  • The target temperature of the oil must be known.
  • The temperature of the supplied water and the temperature of the surrounding air
  • The precise flow that is required
  • The optimum ratio of oil to water flow
  • The oil’s viscosity is a measure of how thick it is.
