Hydraulic Cooling

Cooling Hydraulic Fluids

Heat is terrible for hydraulic systems. Too much of it can damage components and affect the lifespan of your equipment—or worse, cause expensive failures. Almost all hydraulic systems need a way to remove excess heat, which is where heat exchangers come in.

Hydraulic oil coolers are designed to reduce system fluid temperatures through indirect contact with a cooling fluid or gas. The two most common types of coolers are air-cooled and liquid-cooled. Air-cooled units use fans to blow cool air over a radiator, which dissipates heat into the environment. Ambient air temperatures directly affect the performance of this type of exchanger, with warmer temperatures requiring a larger exchanger to perform the same duty.

Liquid coolers circulate hot hydraulic fluid or oil through a shell where it transfers heat into cool fluid flowing through adjacent channels or tubes. Cool utility fluid (like water or glycol) must be available on-site. The choice of hydraulic oil cooler depends on the application’s specific requirements and operational criteria.
