Heat Sinks for Oil
Dozens of fins and coolant tubes quickly dissipate excess heat. Also known as oil coolers, these heat sinks cool hydraulic fluid and lubricating oil in cylinders and compressors. Cooling and flow capacities are based on 50 SSU oil, 1,000 feet per minute of air, a 50° F initial temperature difference, and a 10 psi pressure drop.
Heat sinks with a bypass prevent damage to the cooling fins by diverting pressurized oil. They’re often used in machines that are started up while cold. Once the oil heats up and the pressure drops, flow through the cooling tubes resumes.
Mounting kits (sold separately) are required for installation.

High-Capacity Heat Sinks for Oil
For greater cooling capacity and higher flow rates than other heat sinks for oil, these have a large fan. Also known as oil coolers, they're commonly used to cool hydraulic fluid and lubricating oil in cylinders and compressors. Cooling capacity is based on an initial temperature difference of 50° F.
