Hydraulic air-oil heat exchangers type HPA Emmegi available in PONAR Wadowice S.A.
HPA air-oil heat exchangers are used to maintain the temperature of the hydraulic oil in the temperature range recommended by the mineral oil producer. The excess energy in the form of heat in the hydraulic system is absorbed by the oil cooler. Oil-air coolers prevent unwanted overheating of the hydraulic oil, which can damage the hydraulic system. Too little heat dissipation causes the system temperature to be too high, which leads to poor lubrication properties, internal leakage, cavitation, damage to hydraulic components, etc. The best way to remove heat from the system, i.e. cooling the hydraulic oil, is to use an oil heat exchanger.
The HPA coolers are heat exchangers in which air is the factor that dissipates excess heat.
The radiator fan can be driven by:
The use of HPA oil-air coolers and maintaining the appropriate operating temperature of the hydraulic system brings a number of advantages:
Air-oil heat exchangers are available with a thermostat for temperature control and regulation, and a by-pass valve
