Heat Sinks for Water


A fan cools water as it moves through the tubes to dissipate heat. These heat sinks have flanges with mounting slots for installation in frames and cabinets. Overall height, width, and depth do not include tube ends.
Heat sinks with 316 stainless steel tubes have excellent corrosion resistance to withstand deionized water and other corrosive liquid.

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.

Clamp-On Heat Sinks for Pipe and Tube


Turn your pipe or tube into a heat sink. A hinged design makes these heat sinks simple to wrap around an existing line—no need to cut into your line and drain the liquid to install a heat sink. Multiple fins create a large surface to draw heat away quickly. As they cool down the contents of your line, they heat the space around the heat sink, similar to how radiant heat works.
Secure them together with the included fasteners. You don't need to worry about using heat transfer compounds or putty with these.
Cooling capacity is based on 180° F water flowing through your line at one gallon per minute in a space with an ambient temperature of 65° F and normal airflow.

Cold Plates




Connect these plates to cold liquid lines in process chillers and liquid-to-air cooling systems to cool equipment through direct contact. All have tubes that pass through a thermally conductive aluminum plate. Drill or tap the plate for mounting.
Cold plates with 316 stainless steel tubes can stand up to corrosive liquid and deionized water. Those with fittings let you connect to your system without having to weld or attach your own fittings.

Cleaned and Capped Copper Tubing

- Temperature Range: 32° to 400° F
- Bending Method: Tube Bender
- Compatible Tube Fittings: Compression and Solder Connect
This tubing comes cleaned and capped to prevent moisture and dirt from contaminating the inside. It is also known as refrigeration and air conditioning tubing. Tubing has good corrosion resistance and excellent heat transfer qualities. It is seamless, which provides a smooth interior for unrestricted flow. It can be flared without splitting.
Note: Copper tube size is an accepted industry designation, not an actual size.

Insulated Copper Tubing


- Temperature Range: -290° to 220° F
- Bending Method: Tube Bender
- Compatible Tube Fittings: Compression and Solder Connect
Often used in heating and cooling systems, this tubing insulates refrigerant to efficiently transfer heat between components. It's frequently referred to as refrigeration and air conditioning tubing. This tubing consists of a copper tube insulated in rubber. The copper tubing resists corrosion and has excellent heat transfer qualities. The outer insulation has a closed-cell design, so it prevents moisture from seeping through and corroding the copper tubing. This tubing is generally rigid because of the copper tubing inside and is stronger than plastic and rubber tubing. Use it in medium- to high-pressure applications.

Precision Steel Tubing

- Temperature Range: -40° to 250° F
- Bending Method: Tube Bender
- Compatible Tube Fittings: Compression
With the lowest OD tolerance of all our steel tubing, this tubing is designed for precision applications. Also known as Bundyweld tubing, it is plated with copper and rolled into a tube, then the copper is melted to form a strong cohesive bond. For added corrosion resistance, tubing is finished with a coat of aluminum-based paint or zinc.
