Most people felt that “Air-Oil Cooler” could only be effectively applied to lower Horse Power(HP) hydraulic systems, but with today’s technology, “Air-Oil Cooler” cooling system becomes more efficient for Heat Exchanger solutions. As a result, it could work with higher Horse Power(HP). e.g.: Even an “Air-Oil Cooler” unit with a single fan is able to work efficiently in a 100 HP Hydraulic Power Unit
