Heat Sinks

Heat Sinks for Water

A fan cools water as it moves through the tubes.

Heat Sinks with Internal Pump for Water

To provide a more consistent flow of cooled water than other heat sinks for water, these have a built-in pump and reservoir.

Heat Sinks for Oil

Dozens of fins and coolant tubes quickly dissipate excess heat.

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.

Clamp-On Heat Sinks for Pipe and Tube

Turn your pipe or tube into a heat sink.

Adhesive-Mount Heat Sinks

Remove excess heat by sticking these heat sinks onto circuit boards, semi-conductors, relays, and other heat-sensitive electrical components.

Clip-On Heat Sinks

Clip these heat sinks onto circuit boards, semiconductors, and other heat-sensitive electrical components.

Liquid Chillers

Benchtop Liquid Chillers

Send cool water to equipment right from your bench top without compromising precision.

Precision Liquid Chillers

These liquid chillers maintain a stable temperature within 0.18° F for the most precise temperature control.

Rack-Mount Liquid Chillers

Save floor space—these chillers mount to standard 19" electronics racks, enclosures, and cabinets.

Low-Temperature Liquid Chillers

Chill coolant down to 0° F—the lowest temperature liquid chillers we offer.

High-Flow Liquid Chillers

For more cooling capacity than other liquid chillers, these have a heavy duty pump that can handle higher flow rates and pressures.

Heat Pipes

Protect computers, sensitive electronic components, lighting, injection molders, and HVAC systems from damage by routing heat away from them and toward a heat sink, where the heat can be dissipated.

Heat Exchangers

High-Efficiency Heat Exchangers

Stacked, corrugated plates maximize contact with liquid or steam flowing through these brazed plate heat exchangers for faster heat transfer than shell and tube heat exchangers.

Open-Tank Heat Exchangers

Place these heat exchangers in open tanks to heat or cool their contents by transferring heat from water or steam that flows through passageways in the panel.

Heat Exchangers

Also known as shell and tube heat exchangers, these transfer heat using liquid or steam that flows through the shell to heat or cool liquid in the tubes.

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. They are also known as shell and tube heat exchangers.

Heat Exchangers for Sampling

Cool hot liquid samples to safe temperatures for testing. These heat exchangers are often used to monitor boiler water quality without shutting down the system.

Enclosure-Cooling Heat Exchangers

Cool the air in your enclosure to protect electronic components from excessive heat. These heat exchangers absorb heat in the enclosure, then use cooler air outside the enclosure to draw the heat away, lowering the temperature inside.
