Hydraulics overheating?

As summer approaches, the extra heat in the atmosphere puts more pressure on hydraulic systems. Hyspecs recommends an oil operating temperature of 60°C, and says there are two options to control the situation. • Build a large oil tank to dissipate

the heat. • Install a hydraulic oil cooler that’s capable of cooling approximately 30 per cent of the system input power. Oil coolers typically come as either air/oil or water/oil variety. The air/oil coolers have an electric or hydraulic fan blowing over the fins to cool the oil f lowing inside the radiator.

Oil/water coolers are designed to have oil running through a large outer tube with a separate series of smaller tubes running inside this, containing f lowing fresh or salt water. Call HYSPECS 0800 497 732 or email us on hyspecs@hyspecs.co.nz
