Air Cooled Oil Cooler
Premium Oil Coolers Manufacturer
Oil coolers, also known as D-cup coolers, are vital components used to remove excess heat from internal combustion devices and hydraulic systems. They are primarily used in drain lines where displacement pumps up to 70 bar working pressure are required.
HPP Groups is one of India's top manufacturers and suppliers of high-efficiency air-cooled oil coolers. Our coolers are highly cost-effective and equipped with standard specifications like cast iron headers, Nitrile seals, and Viton seals, designed to endure temperatures above 100°C.
Optimum Efficiency
Maximum heat transfer using air as a cooling medium with zero coolant tank required.
Electrical Insulator
Can be safely used with electrical components since oil acts as an electrical insulator.
Corrosion Prevention
The oil flow acts as a natural lubricant, significantly reducing the risk of internal corrosion.
