High-Capacity Heat Sinks for Oil


Style A	Style B

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.

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.

Bypass—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.

Heat Exchangers for Sampling

Often used to monitor boiler water quality without shutting down the system, these heat exchangers cool hot liquid samples to safe temperatures for testing. Sample liquid flows through the tubes, and cold water from an external water supply flows around the tubes to cool the liquid in the tubes. Cooled sample water then flows out of the heat exchanger for analysis.

1.3 ft² Surface Area	3.8 ft² Surface Area

316 Stainless Steel Tube—316 stainless steel tubes have the best corrosion resistance.

1.3 ft² Surface Area—Heat exchangers with 1.3 ft² surface area are often used for sampling liquid from a boiler.

3.8 ft² Surface Area—Heat exchangers with 3.8 ft² surface area are good for sampling steam from a boiler or for continuously cooling sample water.

High-Pressure Heat Exchangers

With more than three times the pressure rating of standard heat exchangers, these are often used for high-pressure condensing, evaporating, heating, and cooling. Also known as shell and tube heat exchangers, they transfer heat using liquid or steam that flows through the shell to heat or cool liquid in the tubes.

316 Stainless Steel Shell—Shell is 316 stainless steel for excellent corrosion resistance.

316 Stainless Steel Tube—Tubes are 316 stainless steel for excellent corrosion resistance.

Heating/Cooling Capacity—Btu/hr. cooling capacity is based on cooling 180° F process water with 85° F water and a 10 psi pressure difference.
