As no hydraulic system can convert mechanical to hydraulic energy with 100% efficiency, heat is always going to be produced in the system as a byproduct.

This means there will be a rise in the oil temperature that must be controlled in order to optimise the performance of your system.

As the temperature of the oil rises, its viscosity drops and the oil will lose its lubricating properties. This can affect seals and 'O' rings and can ultimately damage the whole system. At best the oil will have to be changed frequently at considerable cost.

Installing an air blast (air blown) cooler ensures the temperature of the oil never exceeds its optimum working temperature.

Air blast coolers can be installed almost anywhere, particularly in locations where water is not available or is too expensive to consider in today's climate.
