DK Turbines is your premier source for aviation power and thermal management components. When your aircraft requires maintenance, you need a partner who understands the urgency of the aviation industry. We specialize in the procurement, sale, and repair of high-quality aircraft oil coolers.
Whether you are looking to purchase a factory-new unit, find a serviceable replacement for an older fleet, or overhaul your existing core, our team is ready to assist. We combine technical expertise with a vast supply network to ensure your aircraft spends less time in the hangar and more time in the air.
An aircraft oil cooler is a specialized heat exchanger. It is the component responsible for taking hot engine oil, extracting the thermal energy generated by combustion and friction, and cycling it back into the engine at a safe operating temperature.
These units are the guardians of your engine’s health. Without functional oil coolers, the immense heat generated by turbine and piston engines would rapidly degrade the oil’s properties, leading to engine instability.
At DK Turbines, we supply units that meet or exceed OEM specifications to make sure this heat exchange happens efficiently, flight after flight.
We understand that finding the right unit with the right paperwork can be a challenge. So, we make this process easy through two dedicated services.
integrated a powerful, user-friendly search feature directly into our website to streamline your purchasing experience.
Navigate to our search bar and enter your requirements. You can search by:
Our tool checks our live database to show you the current availability. If the part is in stock, you can check out or request a quote immediately. If the part is not currently listed, our procurement team will source it for you.
Quality assurance starts with the source. At DK Turbines, we align our inventory with the aviation industry’s standard-bearers. By stocking components for a diverse range of airframes and engines, we make sure that you receive parts capable of withstanding the rigors of flight.
Our catalog features support for equipment from leading OEMs and airframe manufacturers, including:
Sourcing a high-quality replacement part is crucial, as the performance of your cooling system directly affects engine health.
Engine oil’s dual role is to lubricate and transfer heat. Effective lubrication requires the oil to maintain its correct viscosity (thickness). If the oil temperature surpasses the manufacturer’s specified limits, the oil thins out. This thin oil cannot sustain the protective film needed to keep high-speed metal components, such as bearings and gears, separated.
By choosing DK Turbines for your parts, you make sure your cooling system can efficiently dissipate heat. This preserves the oil’s optimal viscosity, thereby shielding the engine’s internal parts from damaging, catastrophic wear.
While we recommend following TBO (Time Between Overhaul) schedules, your aircraft will often display symptoms indicating that the cooled oil returning to the engine is not sufficiently cool.
Watch for these indicators that it is time to use our search tool to buy a replacement:
