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.

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.

Heat Sinks for Water


1 Fan	2 Fans

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.

316 Stainless Steel Tube—Heat sinks with 316 stainless steel tubes have excellent corrosion resistance to withstand deionized water and other corrosive liquid.

Enclosure-Cooling Heat Exchangers


NEMA 12 Enclosure Rating	NEMA 4 Enclosure Rating	NEMA 4X Enclosure Rating, 1,400 BTU/hr Cooling Capacity

NEMA 4X Enclosure Rating, 3,000 BTU/hr Cooling Capacity	NEMA 4X Enclosure Rating, 4,400 to 12,200 BTU/hr. Cooling Capacity

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. Unlike a fan, they seal out outside air, so dust, moisture, and other contaminants can't get in. Because they use ambient air to cool the enclosure, heat exchangers use less energy and are less likely to cause condensation than air conditioners.

All of these heat exchangers meet American and Canadian safety standards.

NEMA 12 Enclosure Rating and IP54 Enclosure Rating—Heat exchangers that meet NEMA 12 and IP54 seal out dust, dirt, and splashing water and oil. Made of steel, these enclosures are powder coated, so they won’t rust in damp environments, but they’re not watertight enough to use outdoors.

NEMA 4 Enclosure Rating and IP56 Enclosure Rating—NEMA 4- and IP56-rated heat exchangers are designed to withstand rain, snow, and washdowns. They’re made of powder-coated steel.

NEMA 4X Enclosure Rating and IP56 Enclosure Rating—Heat exchangers rated NEMA 4X and IP56 are made of stainless steel to resist corrosion in the harshest environments. They stand up to weather, washdowns, and corrosive chemicals.

CE Marked—CE marked heat exchangers also meet European safety standards.

Low-Temperature Liquid Chillers

Chill coolant down to 0° F—the lowest temperature liquid chillers we offer. They're often used when you want to maintain temperatures below freezing, such as in food processing and for sensitive electronic components. They take your fluid down to a constant uniform temperature and pump that liquid into your cooling system. Monitor the temperature and pressure of the coolant on the LCD display and change the settings using the keypad. They have a window to quickly check the fluid level. This window also acts as a spot to drain or fill the chiller.

Cannot Be Sold To—Liquid chillers cannot be sold to the listed areas due to chemical regulations.

Liquid Chillers

Circulate water or glycol solutions to prevent spot-welding systems, molds, lasers, and other temperature-sensitive equipment from overheating. These chillers provide constant, uniform temperatures. An internal tank ensures liquid flows in a continuous loop. Adjust the set temperature with the keypad.

Bypass Valve—Chillers with a bypass valve recirculate liquid in the chiller if the outlet is obstructed.

Cooling Capacity—Cooling capacity is based on a 65° F liquid temperature and a 95° F room temperature.
